I remember the day when computers were first in my classroom. I laugh sometimes just remembering the green front Apple and Orange font IBM computers. When using them little did I know one day there would be graphic rich multimedia with unlimited connectivity to the world and information.
I also remember my friend as a child who had a computer science father. As a birthday gift he gave his son two little boxes with 8 numerical buttons and one little red LCD display on each box. These little boxes were a way for me and my friend to send codes back and forth from each other from our phone lines when at home. We created our own code talk to decipher messages. We felt like spies and had a great time messaging nonsense for hours.
Little did I know as a child that these seemingly simple things would grow into the powerful and world dominating PC and Internet. Even less did I know the impact it would have on all the lives of the world and how easy and fun it would become. As a naive child, I would never imagine the evil that would lurk to destroy such great technological advances.
With the birth of the Internet came the birth of viruses, spyware, and spam. The Internet world could now virally be infected with computer destroying codes almost instantly worldwide along with pop-up ads all over your computer screen and your inbox bombarded with propositions of the unthinkable and bizarre.
Once introduced, the world forever would be on their toes watching their backs for this malicious onslaught of computer created menaces and dangers . The industry created to thwart the destructive codings has boomed and never looked back and it is doubtful that it will ever be out of demand as more lives rely on the Internet and the computers used to access it.
Hundreds of different anti-virus, ant-spam, and anti-spyware software exists today and some can come at a bargain while others can cost you an arm and leg. Some are excellent while others are mediocre, but for today we will discuss good and honest protection that is free.
Spam as we all know can ruin a good visit to the inbox. For protection against spam you must be responsible with your email address and be careful who gets it. Applying for bogus free offers and money making schemes can open up your whole account to the dreaded inbox disease.
If you are needing spam protection you can open up a free email account with Yahoo Mail or HotMail and receive free spam protection with the service without any additional software or setup. Yahoo offers a yearly paid account with additional spam protection if the free version is not enough for you. Yahoo charges about $20.00 a year, which I myself subscribe to.
With spyware you can expect unexpected pop-ups, search intrusions, as well as the possibility of identity theft. This makes spyware no laughing matter and lucky for you you don’t have to pay to be protected. Lavasoft and AVG are just two companies that offer outstanding free anti-spyware software for your computer. Even Yahoo has gotten into the act and have given their toolbar users free spyware software that can be launched from their toolbar. I recommend running it once a day.
Viruses can literally destroy your operating system and even your whole computer which makes this last threat one of the most dangerous when it comes to your PC. You would expect to pay hundreds of dollars perhaps to protect your computer or maybe an annual subscription which is common too. Why even pay when you can get it for free?
There are two great anti-virus programs out there that you can use free for your home computer without any catch other than maybe a registration. I highly recommend these two products and use them for my own computers completely free.
Anti-virus #1: AVG has an anti-virus download that takes care of all the virus updates daily and scans your computer everyday at a specified time which is convenient for those who forget to protect their PCs.
Anti-Virus #2: Avast is an excellent program for keeping both spyware and viruses off of your computer and in the gutter where they belong. They have a more complex registration which requires email authentication and online registration, but only takes about 10 minutes of your time, a lot less time than the hours you have to work to buy a new computer or OS.
Don’t let the word free deter you from these great resources. It is amazing what these companies are offering the general PC population and you should take full advantage of their offer. I use all the mentioned software myself and it just goes to show, some of the best things in life really are free.

Is your computer is running slowly and seems to be at the edge. You may have a virus on your computer. So, let us see, what is a virus? what it can do for your computer? How can you do protect your computer from it? The virus is a malicious program which replicates itself through your computer without asking you or takes permission from you. This program can infect your files and make it malfunctioned. For example, you may open a Microsoft word file and see it failed to open. Assuming that the cause of this failure is a virus, and then you will likely to see other files is malfunctioned as soon as one file is failed due to a virus on your computer. In essential, a virus is large collection of instructions attached to one of your programs. These instructions can be getting from different sources such as browsers when you open the internet, a link in email, floppy disk, flash memory, or others. When one of these programs is opened, these instructions are executed along with the original program you opened and load itself in the memory, and then it can write itself to other files in the computer. In fact, there are two strategies the virus can infect with. The first one is called Nonresident strategy. In this type of infection, the virus looks for other files  and resources to infect only on the local computer. In the second strategy, which is called, Resident strategy, the virus looks for other hosts to infect if it is connected to a local network. The most important is how to prevent these viruses from your computer. The common technique is to install an anti-virus software on your computer. This software works by detecting viruses on your computer. It has many techniques to detect that there is an existing virus according to software vendor. It can detect it based on signature in the file it scan. A signature is a certain pattern it looks for and if exists then it decides that a virus exists. Every sofware that uses thuis technique has a database of this signatures which represents the most common viruses. Some anti-virus sotware also detect by looking for the behaviour of the file being opened which is called heuristic detection . A second technique to prevent your computer from viruses is to backup your data. If some files is infected on your computer, you will find some copies of your data. You can store it, for example on CD, or DVD.

Let’s talk a little about the impact of viruses, Internet related threats and how they effect your computer and privacy.

First off, is it really necessary to have anti-virus and firewall software installed on your computer? Afterall, with only 200 new threats created daily, who really cares? Is it really that big of a deal if hackers are able to access your computer, look through your data, user names, passwords, and account information? Seriously, is identitiy theft really that important to you? Or what about the viruses that cause your computer to go so slow you think you will never be able to load your Internet browser. Why should you worry about malware that can cause your system files to be destroyed or your favorite family photos stored on your computer to disappear in an instant? Does it concern you that your email can be sent to thousands of spam sites and pop-ups are all over your screen offering you software to fix your computer?

Any idea what causes these types of issues? How about malware, which broken down is short for malicious software such as viruses, trojans, worms, rootkits, spyware, adware, I think you get the point. Oh wait, I forgot, you have a customized super sized computer that is not vulnerable to viruses. When I hear people tell me this, I tend to wait and act surprised when they come back saying, “oh no, I got a virus”.

It does not matter how sophisticated your computer is, you are vulnerable to malware! If you don’t have internet security software installed on your pc, you are at risk of being infected with viruses, spyware and even hackers that want nothing more than to steal your information.

So what should you do now that you already have viruses on your computer? Well you could download the latest internet security software and hope it will detect, delete or repair the infected files. Many times you will have to do a re-format of your harddrive which will cause you to lose everything on your computer so be sure to save what you want first. If you do a re-format, it has to be done properly, or it will not delete the viruses. I would recommend you to contact your local computer shop.

Although Internet security and anti-virus software will protect you against these threats, no software is guaranteed to block 100% of all malware. Many of these threats are found on websites that you visit and files that you download such as video’s, music and pictures. If you use peer to peer file sharing, I am sure you already know all about viruses and spyware. Want a hint? Stop downloading from those sites and you will stop getting viruses.

Okay, here are a couple internet security software programs I recommend that offer the best protection, features and support. First is Security Shield 2008, this is a rebrand of F-Secure and is absolutely amazing and easy to use. Another is Kaspersky Internet Security, another well designed software program with hourly updates. Learn more or review our recommended Internet Security Software ReviewsVideo Games

In today’s world of ever evolving technology more people are taking a more proactive interest in their privacy and security online. There exist some commonly held misconceptions, for example, that Online Banking is dangerous and insecure. However the truth is that this is simply not the case provided you adopt some basic measures to protect yourself online. Simple protection need not be expensive or complex. There exist many free & well-respected products, as well as the ever growing range of commercial brands. Virus protection should be considered essential, and an emerging leader is AVG Anti-virus (www.avg.com), which is available for free and more than adequate for most users needs. Often overlooked is Anti-spyware software, such as Ad-Aware (www.lavasoft.com). This type of software specializes in finding threats such as personal data gatherers. By combining these two types of software you will have an adequate amount of protection online. Versions of Windows currently available also include a Firewall, which, when properly configured helps prevent hackers from exploiting vulnerabilities in your computer. Remember that installing the software alone won’t be sufficient. You must regularly run scans and install updates to keep your protection current. Lastly if you have a wireless internet connection, it is essential you use the latest encryption scheme to prevent outsiders from viewing your online activities. You need to use WPA2 (or Wi-Fi Protected Access) which is still considered secure (ask your installer to do this for you). Remember to keep your computer up-to-date by performing regular Windows updates, and take regular backups of your files. Also consider switching to an alternative internet browser if you use Internet Explorer as it has a long history of security failures. We recommend using Firefox or Opera. WP Autoblogging Plugin

For this article, I decided to create a list of 10 free programs you can download to keep your computer secure. This list of programs will help you protect your computer from Viruses, Spyware, and hackers. All of the programs listed here are highly recommended, and like I said, all have a free version available.
I should note though that many websites that carry articles do not allow more then a couple links in the main body of the article. Because of this, I am unable to include download links for each program. However, if you do a search for them on Google, you can find where to download them. Alternatively, you can visit my website where I have uploaded this article and included links inside the article to download each program. The web address is listed in my author info.
Anyway, let’s get to the list of 10 programs you should download to protect yourself from Spyware and Computer Viruses and keep your computer safe.
Ad-Aware
Ad-Aware is one of the oldest Anti-Spyware programs available and also one of the best. Ad-Aware has been around for over ten years now. Over the ten years, Ad-Aware has been a top notch program and it doesn’t look to be changing anytime soon. If you do not have Ad-Aware protecting your system, then I highly recommend you download it right now.
AVG Anti-virus
With McAfee and Norton on the market, many people are under the impression that you will have to pay money for virus protection. This is wrong! There are free anti-virus solutions available and AVG is one of the best. AVG has all of the usual features and it’s highly recommended that you download AVG Anti-Virus if you don’t already have a virus scanner.
Hijack This!
Hijack This! can be a great program for helping you get rid of some tricky Spyware. Beware though, you really need to know what you are doing when you are using Hijack This!. Hijack This! isn’t for beginners. However, it’s worth downloading and keeping around so if you ever do have a tricky spyware problem, an expert online can help you use Hijack This! to get rid of it. Because honestly, most experts online are going to ask you to download Hijack This!.
Malwarebytes Anti-Malware
Malwarebytes Anti-Malware is newer then some of the other anti-Spyware products, but don’t let that discourage you. Malwarebytes Anti-Malware is a great tool for protecting yourself against spyware. Like Ad-Aware, it can do a complete scan of your computer and most spyware problems you are having you can say goodbye to thanks to this program.
Spybot Search & Destroy
Spybot Search & Destroy reminds me of Ad-Aware, it has been around a long time and has stood the test of time. Spybot Search & Destroy may not be as pretty as some of the other anti-spyware programs, but that’s okay because Spybot Search & Destroy means business. Spybot Search & Destroy should have all of the tools you need to protect you from Spyware even if you don’t download any other program listed here.
SpywareBlaster
What can I say about SpywareBlaster? SpywareBlaster is a really cool program. SpywareBlaster isn’t a scanner, instead, it’s purpose is to prevent Spyware from getting onto your system in the first place. SpywareBlaster has a database of thousands of harmful Active X Plug-ins that it blocks. Just download SpywareBlaster, install it, click to enable the protection, and that’s it. SpywareBlaster doesn’t even need to be running all the time. A very useful program that should be included in your list of programs you use to protect your computer.
SpywareGuard
SpywareGuard is simlar to SpywareBlaster, it tries to prevent Spyware from getting onto your system. However, SpywareGuard works in a different way. SpywareGuard works by monitoring your computer for typical Spyware-like behavior. If SpywareGuard spots anything, it will alert you. The downside to this is that you need to keep SpywareGuard open for it to work. On the plus side though, it means SpywareGuard doesn’t need to be constantly updated, since it doesn’t rely on definition files.
Startup Inspector
Startup Inspector is a program used for monitoring and disabling items that run when you turn on the computer. So how does that relate to this list? Well Startup Inspector can really be handy in fighting Spyware because a lot of Spyware programs will be set to run when you turn on the computer. Before you turn off the computer each night, take a quick look at Startup Inspector and see what is set to run when you turn on the computer next time. See anything suspicious? If so, go ahead and run a scan with another program listed here. But remember, you first noticed something suspicious thanks to Startup Inspector. This is why I included it in this list.
Update Windows
Okay, guess what? I lied. This isn’t even a software program. Regardless though, this has to be included in this list. One of the biggest ways your computer can be attacked is through security holes that were left open from not updating your operating system. Do your computer a favor and go online to WindowsUpdate and update your computer right away.
ZoneAlarm
Finally, we come to ZoneAlarm. ZoneAlarm is a firewall and will monitor all ingoing and outgoing connections on your computer. This is very useful for keeping your computer safe, because Zonealarm will block unauthorized connections to your computer. Basically, ZoneAlarm stops hackers. Great software!
In all honesty, if you don’t want to try all of these programs, even just download one or two. Having one or two of these can still make a big difference with your computer. It can be scary with so much Spyware and Viruses on the internet. But now, you have the information you need to stay protected. Good luck make your own website

Where do computer virus myths come from? It’s hard to say. One minute you think you know how they work, and the next you’re being told you can get viruses from cookies, Javascript on Web pages, viewing GIF files, and so on. All nonsense of course, but it’s understandable to feel concerned. And it’s a lot healthier than completely assuming you’re safe from computer viruses, because unless you get rid of your PC that certainly isn’t true.DefinitionsA virus is a computer program that is designed to enter PCs without the user’s knowledge, then replicate itself throughout the system. Some viruses carry a ‘payload’ which activates eventually – this can be anything from displaying a silly message on the screen to wiping out all the files on your hard disk.An important step to protecting yourself is to realize when programs are running on your PC, because viruses can exploit them all. The first opportunity occurs when you switch on your computer. Both floppy disks and hard disks contain a little ‘boot sector’ program, which either displays a ‘you can’t boot from me’ message (on a normal floppy), or loads your operating system (on a hard disk). Boot sector viruses infect this program, so loading into memory every time you start your PC, then copying itself to every floppy disk you read.Other viruses target files containing program code; every time you run the infected program, it loads itself into memory, then might copy itself to other programs. Not just .exe files, either – .com, .dll, .ocx, .drv, .sys, and so on, are all at risk. After copying itself the original application continues to run and you never realize there’s a problem, until the payload hits you.Still, at least data files are safe, right? Wrong. Many Microsoft programs enable files such as Word documents and spreadsheets to contain program code (macros). This is great for automated office applications, but also presents another risk point. Just viewing a document carrying a macro virus can be enough to infect your whole system.Don’t PanicAlarmed? You should be, but there’s no need to panic. Modern antivirus software has some powerful features to prevent you getting infected. Two methods are particularly common.The first involves maintaining a table of virus signatures – sequences of bytes that occur in the virus program itself. Scan a downloaded file, and if you find that signature then you know the file might be infected. The signature approach is useful and quick, but can give false alarms if the signature occurs innocently somewhere. It’s no use on new viruses that aren’t in the signature file yet. And some viruses are polymorphic, meaning they change their own structure and just don’t have a consistent signature anyway.Fortunately the best antivirus software has another weapon in its arsenal – the heuristic approach. This involves looking for virus-like behavior – writing to an executable file, perhaps, or copying information to the boot sector. It’s a clever idea, and can even help detect completely new viruses.Protect YourselfInstalling good antivirus software is a great idea, but it’s only the first step. There are lots of other things you can do to help protect yourself. First you need to keep the software updated to cope with new threats. Some antivirus programs can update themselves automatically, but it’s still worth visiting the author’s web site every week to find out what’s going on. And don’t forget about the security settings on other software.There will always be some risk from viruses, but good antivirus software, combined with regular backups, should mean you can recover, if the worst happens.

Amazon.com Review
Books such as Richard Preston’s The Hot Zone thrust the deadly Ebola virus into the spotlight, but they can’t match the first-person perspective of Virus Hunter. Author C. J. Peters is an ex-army colonel who has spent his professional life studying deadly pathogens in the lab and in the wild. He spins a drama- and adrenaline-filled true tale of virus hunters, which is gripping despite its occasional tendency to grow verbose and detour into personal history. (more…)
