Rebooting doesn't do anything.
I moved the files from the chest to scan with Malwarebytes.
A full scan showed only this...
Memory Processes Infected: 0
Memory Modules Infected: 0
Registry Keys Infected: 0
Registry Values Infected: 0
Registry Data Items Infected: 0
Folders Infected: 0
Files Infected: 3
...
Files Infected:
C:\WINDOWS\cru629.dat (Trojan.FakeAlert) -> No action taken.
C:\WINDOWS\system32\wisdstr.exe (Trojan.FakeAlert) -> No action taken.
C:\WINDOWS\svchost.exe (Trojan.Agent) -> No action taken.
But when scanning the indidual files via right click, the svchost.exe was not shown to be infected.
On the other hand, Spyware Doctor notified only cru629.dat as a "backdoor.Small!ct".
Another quick scan by malwarebytesshows:
Files Infected:
C:\WINDOWS\system32\wisdstr.exe (Trojan.FakeAlert) -> No action taken.
C:\WINDOWS\cru629.dat (Trojan.Downloader) -> No action taken.
C:\WINDOWS\svchost.exe (Trojan.Agent) -> No action taken.
At the present, I've moved all three back to Avast's virus chest.
EDIT: I've fixed the opaque desktop icon problem by deleting "tets" under desktop properties>Desktop>Customize>Web
EDIT2:
http://support.microsoft.com/?kbid=314056If svchost.exe is found under C:\\WINDOWS\system32 , then this file under C:\\WINDOWS isn't the real file? There is another svchost.exe under system32.
