What is it?

win32/adware.virtumonde virus (or Vundo) is a Trojan horse virus which is said to infect your system by going through Java. For those of you who don’t know much about computers, don’t worry it’s not Java that is the problem, so don’t get carried away with yourself and delete Java! The virus usually attaches to the system using bogus Browser Helper Objects (BHO) and DLL files attached to Winlogon and Explorer.exe. This can cause a great deal of trouble and is rather frustrating. After you review the material presented below, follow up on my advice to ensure your computer’s safety.

Have I got it?

Most computer viruses act just as human viruses hat can make you sick. It first starts off with symptoms and the symptoms for the Vundo virus are multiple pop ups. When you have Vundo, it causes the infected computer to use the web browser to trigger pop up advertisements You will quickly be able to recognize them because they usually claim to have software which will detect viruses on your computer and will “fix” your computer – when obviously they won’t. This is a scheme to either get you to buy their software, or a way for you to activate more viruses.

You also may notice pop ups on your computer when you start windows, usually saying something about DLL files (with bizarre names) you will notice that these files are in the Windows/System32 directory and pop up when your computer starts, after you log on.

How to get rid of it?

Like most viruses, fortunately there is a way to get rid of it. Obviously, having a good anti-virus program will eliminate the need to even ask this question but if you are unaware of the best packages then I suggest, AVG (which is a free tool to get rid of spyware and viruses), Norton Anti-Virus and MacAfee. All these software packages are available in the shops and on the web. AVG is only available on the web but is easy to find – simply “Google” AVG and it should be available for download from somewhere.

If this doesn’t immediately work then you may need to restart your computer in safe mode and run the virus scan again. Sometimes these viruses hide quite well. Once you’re all sorted make sure you run your virus protection regularly and if you have a software package which has real time protection – use it. There are many types of viruses around at the moment and it is easy to get one when you are not protected. Using anti-virus software with regular updates and online real time protection is the best way to stay safe online in today’s world.

You can protect your pc against different security threats prowling on the cyberspace by using free tools. The protection these programs offer is quite good. You may wonder why an earth to use so many spyware scanners? The answer to this question is simple. One scanner was not able to detect all threats, so it was appropriate to use several. All these spyware and virus detection and removal tools worked well and did their mission. Spyware Doctor is worth to mention, because it was the only program to detect register files infection. This phenomena reduced the performance of my computer remarkably, if it appeared.

When I bought a new computer, I decided to purchase Norton Internet Security 2009. The brand name was familiar to me previously, because as a Yahoo mail user I happened to know that Yahoo scans all attachments by using Norton Antivirus. So I thought it was a good choice. I have now used  Norton Internet Security 2008 and 2009 over one year. I was able to upgrade to the new version for free. After I started to use the 2009 version, I noticed that it was more user friendly and faster than the 2008 version. Many times when I used the older version I wondered, why I have to do so many clicks in order to get my database updated. Now in this version of 2009 updating is easy and automatic as well as scanning.

The free tools I used before detected several times all kinds of spyware, adware and viruses on my computer. It seemed that there were certain “security holes” in this system through which malware was able to access into the computer. In addition, it took time to scan the computer by using several different scanners. Norton Internet Security 2009 provides more comprehensive protection against all kinds of security threats. It has antivirus, spyware protection, two-way firewall, intrusion prevention, operating system and application protection as well as web site authentication. Based on my experience, I can say that Norton Internet Security 2009 has provided a very good protection and it has kept my computer clean. It has not even detected any serious infections.
