that trend micro house call is found at www.pc-cillin.com
I use it all the time
Also of course if you don't already have em get Adaware, and Spybot: Search & Destroy, use both of them plus the www.pc-cillin.com
to get all the pr0n residue off your computer
Just messin with ya there
Virii or spyware is the only thing that I can think of as been said by a couple people already that would cause a jump like that.
If you don't have that Ipod thing then get rid of itl.
Also go to www.download.com
and search for 'Startup Control Panel' and install that program.
Then go to Start>Control Panel> Startup and delete anything that you know doesnt belong there.
