I´m not sure it is a virus. That´s what I´m trying to find out.
A full system scan with avast finds nothing, the same happens with Trendmicro Housecall. But as I mentioned befor, the last time I checked for rootkits with Rootkit Buster I got a few entries like this:
[HOOKED_SERVICE_API]:
Service API : ZwAddBootEntry
Image Path : C:\Windows\System32\Drivers\aswSnx.SYS
OriginalHandler : 0x8313f4be
CurrentHandler : 0x8fa7efc4
ServiceNumber : 0x9
ModuleName : aswSnx.SYS
SDTType : 0x0
A recently installed avast on my Windows 7 machine, so I´m guessing that these are API hooks from avast, but I´m just trying to confirm everything is ok.
Thanks.
