My friend gave me a memory stick that was having problems.  I stuck the memory stick and soon after, my "run" was gone and "system restore" was disabled.  I guess I fell for this one.  I system restored but worried about the XP.  Should I reformat and reinstall XP.  I'm running a full scan now using Trend Micro.  Any advise

You don't have to reformat unless you really want to.

I would just scan the system and if things are running well then it's good and no need to reformat.


Run these tools and show us the logs.
Download Malwarebytes' Anti-Malware to your desktop, check for the tool's Updates before running a scan.

you might also consider checking out files in the root directory which have wierd names. also check the windows/system32 directories.

easy way to check is by sorting the files by date and checking the lastest files in the directory.
anything suspiciuos look it up on google

Try using this it generally will remove any threat whether active or passive specially the threats from usb sticks. next time you press shift key and then insert a usb stick and never double click the usb drive letter always right click and click on explore that way you do not execute any malicious code if present.
