Hi there -
I am directed by one of the kind BC moderators to open a new thread after initially posting under Malware. I will copy all my posts from there as it will explain everything quickly:
Hi there, good folk of Bleeping Computer :-)
PC, Windows 7 Home Premium, 64 bit. I have chosen NOT to install the Windows Updates - this may/may not be relevant. Malwarebytes Free, Avira Pro.
I first noticed there might be a problem when I was attempting to download regular definition Updates for Malwarebytes. The download could never quite complete - it froze up 3/4 of the way through. Same result after several attempts.
I also noticed the internet was running very slowly (and normally it's pretty quick). Another change in behavior.
I uninstalled Malwarebytes using Control Panel. I also downloaded the mbam-cleaner file from the MB site. BUT I was unable to open this mbam-cleaner file beyond the Run window (which I clicked), only to get the error message "mbam-cleaner.exe is not a valid Win32 application".
Same result when I tried to run rkill - same equivalent error message: "rkill.exe is not a valid Win32 application".
Definitly something is awry. These are very likely to be good files, and something is choosing to block their opening. I've never seen this error message before. I have made no changes whatsoever to my registry or startup - nothing at all.
Otherwise the computer still appears to be running as it should. I am writing to you from my laptop.
Any wisdom very much appreciated.
All warmest wishes,
I would suspect a Zeroacces infection..
Please follow this Preparation Guide and post in a new topic.
Let me know if all went well.
Heya - many thanks for your help.
I downloaded FRST64.exe and attempted to run it, and, again, as soon as I click Run, up comes the same error message saying "FRST64.exe is not a valid Win 32 application" and it doesn't go any further than that.
This bad stuff is stopping everything dead in its tracks, so I can't even diagnose the problem with FRST!
All best wishes,
Ok, go to the other forum as in the Guide. Start a new topic "cannot run tools"
Mention in the body what you said above and they will get in.
I am posting from the 'infected' computer, so the unit still has considerable functionality, despite whatever bad stuff is going on.
Any thoughts? Your help is GREATLY APPRECIATED, believe you me :-)
