Is "C:\Windows\system32\winlogon.exe" a real/false virus or infected file?

BTW, should I try the latest Avast Beta?

There’s no beta version atm.
Latest stable build is 6.0.1125

@ drgrafix / Mike,

Essexboy is not done with you yet. He needs to remove some malware-removal tools from the machine and give you further instructions.

Then ran the Avast! quick scan and it reported three (3) high severity infected files;

Two (2) were listed as C:…\A0035733.exe and A0035734.exe Threat: Win32:patched-RP [Trj]
One (1) was listed as C:.…\A0035750.exe Threat: Win32:Bamital-AO

Question: When you ran the Avast scan and it found malware, is it sitting in the Virus Chest? Open the Avast GUI > Maintenance > Virus Chest. If anything is there, can you give us a screen shot of the Virus Chest? Thank you.
