.Doc Files Change To .Exe Files When Copied

  • 0

When I copy important .doc files to my memory stick it turns into .exe files which my anti virus picks up as trojan threats. I’ve changed file names, I formatted my memory stick and it keeps happening. How do I stop this from happening?????

  1. If you right-click on those files, then click Properties, you will see the full name of the file, including the extension. Chances are the name includes spaces that are pushing the extension out of sight.

    One more trick that might work is System Restore, if it’s activated and you have a restore point back far enough. Here are instructions: http://support.microsoft.com/kb/306084

    It’s hard to know what to do without seeing what’s going on. The trojan has a hook in the system somewhere, probably a root kit, which is hard to get to. The scanners like MBAM and SAS, which I mentioned above, are better than most at getting at them. If I were in your shoes I would go HERE and run down the list of online trojan scanners. One of them might pick up what’s affecting you.

    Actually, before doing that, I would run System file checker. Go Start /Run/ cmd and then enter SFC.EXE /SCANNOW . Since the hook involves copying, which I suppose is normally an explorer function, it may have replaced a basic system file. You’ll need an XP disk in case SFC finds a file that needs restoration.

    Or if you’re near southern NY, bring the machine by. <smile> Good luck.
