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,
Ralph

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,

Ralph

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.

Hello,

Now that you have posted a topic here: http://www.bleepingcomputer.com/forums/t/576013/cannot-run-tools/ (which I have moved to the appropriate forum), you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a MRT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the MRT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the MRT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the MRT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days to get a response but your log will be reviewed and answered as soon as possibleI advise checking your topic once a day for responses as the e-mail notification system is unreliable.

If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.

To avoid confusion, I am closing this topic.  Good luck with your log.

Help us help you. If HelpBot replies, you MUST follow step 1 in its reply so we know you need help.
