100% CPU when online

[vecheka]

I am using MS Wind XP Home.  When I connect to my network at home (wireless) to go online, my processes go to 100%.  When I disconnect, it drops to normal.  This happened once before and there was a problem with my wireless card driver and the printer driver.  This time, I took the printer driver off and all mention of a printer off.  The problem is still there.

I have run AVG, Trend Micro Housecall, Spybot, MS antispyware and adaware but nothing helps.  The only things I have connected to the computer is my keyboard (PS2), wired trackball (USB), monitor and speakers.

Any help would be great.

Do the scanners find anything?

Spybot and Adaware did show some spyware and deleted them but it did not change anything.  MS antispyware, AVG and Trendmicro did not show anything.

I have also checked msconfig to see if there is anything starting that should not be but it looks fine.

Install a firewall and see if any programs are trying to contact the Internet that have no business doing so from your PC.
