Hello 30rndmag,
Before this problem, how much was your system using on the networking tab?
Download
SilentRunners.vbs
Unzip it to a permanent folder.
Read here how to unzip/extract properly:
Help removing and preventing spyware - Compressed folders XP
Start
SilentRunners.vbs
When your antivirus is giving an alert, do not block this. Allow the script.
When the scan is done, notepad will open with a log in it. Please close this again.
I'll need that log later.
Normally that log is saved automatically in your silent runners-folder.
Post the log it created.
Thanks.
