Use the right antivirus!

I would like to share a painful experience with the Antivirus applications we trust!

Few days ago my home PC got infected with a worm (IM-Worm.Win32.Sohanad.t) that attacks the Windows OS, disables all important tools including:
Task manager, regedit, msconfig, ..even the command prompt!

It creates its copies in most drives, primarily in removable ones and creates autorun.inf to auto run itself, creates a copy of itself (exe file) for each folder in the removable drive!

So, you may ask, didn’t I have an updated antivirus? Yes, I had and that’s the point of my email. I had Norton Antivirus 2005 with the latest definitions updated. Unfortunately even after manual updates and manual scans on the infected exe files it couldn’t find any threats!

More bad news! I tried all of the following top most antivirus and anti-malware applications but they couldn’t detect the virus:

PC Cillin 2004 with updates, Adware Professional with updates, Spyware Doctor, SpyBot Search & Destroy!

So I did some googling to learn which are the current ‘top 10’ antivirus applications. I found ‘Kaspersky 6’ to be the top most one in several ‘good’ web sites. I never heard of it! Interestingly Norton, Trend Micro, McCafe are not in ‘top 5’.

I downloaded and updated Kaspersky and it could detect and clean the virus very well! I installed it in my office PC and it got 2 spywares which our default Network antivirus couldn’t find! Don’t know how long the spyware was in my PC!

Summary: I suggest all to recheck the ‘top 5’ list of antiviruses to get ‘true’ protection from latest viruses/malwares. I found Kaspersky good for my case.
