I've got some problem on my machine and was fortunately able to get rid of one part of the problem using AVG and Avast. Unfortunately NOD32 doesn't detect it. At times while I use the PC there is a file with a random number generated that is placed in the System32 folder and is a six digit number - 554343.exe or the like. AVG or Avast, whichever is running, will blurt out a warning stating it is a Win32/Heur attack. It will attempt to send out thousands of emails using my PC. NOD32 was not finding this file and I was having a problem. Unfortunately despite running NOD32, AVG and Avast, I still can't figure out how this file is being placed on my PC at random times while it's on. A weirdness is that when my PC boots up, I see 2 My Documents folders opening up (and not with my default details but in a different view.) I looked at all the solutions and none of them work, e.g. WinLogon folder and delete extra items after the comma, go to msconfig and remove multiple items for startup of explorer or other such solutions. I'm wondering if this happening is related to one of those files. Regardless, NOD32 has unfortunately been useless in helping me with the above issues.
