Welcome to the forum pmc_762

I assume you have restarted the modem, cleaned out your cache (temporary files), defragged your hard drive, and did error checking?
http://www.testmy.net/forum/t-4257Have you also checked out using WIndows Defender, AVG Free anti-virus and spyware, or Spyware Blaster. Also have you tried running any of these in safe mode?
Try some of those and post back any info you might need.
Good luck.
