When trying to instal ANY antivirus (kaspersky, avg(wich was installed and suddenly dissapeared)) installation stops and there is error: cant open ..... file, and it doesnt want to continue.....

P.S. I tried with AVG 7.5 Free, AVG 7.5 Trial, AVG internet security, Kaspersky 7.0, Zone Alarm Pro, only Ad-aware installed......

Judging by the behaviour, I am sure your pc is infected already with a virus and that's what is preventing your antivirus from being installed.

I would suggest you to go for an online scan. Below are some of the list of online scanners....

First try with these online scanners.... if problem persists then ask the question again.

Do you have administrator access?? It will usually tell you that you don't, but this would be the first thing to check in my book!
Use an online scanner to check your computer. Hopefully the scanner can remove it. If it can't, here's how to manually remove it:

1. Open the registry editor. (Start%26gt;Run%26gt;regedit)
