Hi...
Picked something up from the net but cant seem to isolate it.
On my taskbar i have an icon that oscilates between a no entry sign and a green disabled person sign.
Every few minites or so a blue dialogue box pops up in the lower right hand corner and tells me my computer is infected and there is virus activity present.It prompts me to log on to the net to various antimal software websites which i am reluctant to follow in case of a scam.

Also I am get an annoying system message (glashing exclamation mark in the taskbar), saying the PC has been infected with OHPE ver.4.12_23/Spyware/else. Upon clicking it, it opens an ad of some antispy software or [bleep] popup.

My webpage has changed to www.theguardservices.com and no matter what i do i cant remove that as my homepage. I have scanned my computer with Microsoft antispyware and also downloaded Panda antivirus just to make sure i dont have any virus...but nothing helped.

I am getting tons of popups if i leave my computer on and also my comcast broadband stopped workin...right now im using my wireless connection. I don't know what to do! PLEASE HELP SOON!
here is my hijack log....
