Then again...if your friend isn't willing to register at TechGuy...well, here's what I'd like her to do...
If she has any antivirus software, have her update them, if she can get to them and run scans with it. Have her pick the option in the antivirus software to do a Full or Thorough Scan, depending on what company she gets it from.
But before she does do a scan with her antivirus, I want her to download Spybot Search and Destroy if she doesn't have it already, have her update it, immunize.
Also, have her download AdAware SE, Personal, I cannot remember the name of the AdAware scanner now. Update it, set it to full scan, then close the program.
Download and install, then update SpywareBlaster if she has XP.
After all this, have her reboot the computer into Safe Mode, then have her run the scans, one by one, till ALL of the programs say she's clean.
But she's not quite done just yet. Hopefully it'll solve the problem, but if it isn't, I'd like to know.
