Trace process which changes filesystem Windows 7 x64 Enterprise edition

There is some malware process which is writing the folder $RECYCLE.BIN to every drive in my system. How can I find out which process is doing that. Is there a sysinternals tool? i'm pretty sure of some virus activity

anti-virus

  1. The procmon utility will do what you're looking for, but if the virus writer is any good at what they do it won't catch it. If there is a rootkit on that system (very likely) then it is most assuredly hiding the virus processes from the Windows environment.

    However, it's still worth a shot.

  2. I could be wrong, but "%Recycle.bin" is actually a legitimate Windows folder. It's literally where the "Recycle Bin" goes (each drive has an individual one). If you disable the "Hide Protected Operating System Files (Recommended)" under Tools>Folder Options>View you can see these. So the malicious process your speaking of is a little program called Microsoft Windows 7. :D

    Edit:any Windows user should be able to un check that box and see these files Another thing you can do to test though is Right click on the $Recycle.bin folder and go to properties Note its size delete something large(obviously a copy of it would be better you don't want to delete anything important!) Check the properties again, it should be larger(the size of whatever you deleted larger to be exact
