Help! It says that the infected file does not exist!

I get this message from avast every time I boot up the computer:

A virus was found!

filename: C:/windows/system32/zsys1.dll
malware name: Win32 Trojan-gen (Other
malware type: Virus/Worm
VPS version: 0624-0. 06/11/2006

Reccomended action: move to chest

Anyway, when I try to move to chest, delete, or do anything with it (even “no action,”) I get this message: “cannot process C:/windows/system32/zsys1.dll.” Then when I click ok, avast pops up again, giving me the exact same virus information with the exact same options.

Hi Tohoya,

Your infected with Greatis spyware. For removal instructions read here:

After you got rid of this spyware infection, and did an online scan your for spyware here: http://www.spywareguide.com/onlinescan.php

When your computer is completely free of malware, then install Ad-aware free, Spybot S&D and SpywareBlaster. But, mind you only after your computer is clean!!

Furthermore use only one AV solution like Avast, and install only one software firewall, like for instance Zonealarm,
