I own a compaq pc with vista home basic edition and have kaspersky anti virus running on my laptop. I use firefox for browsing and since a few days, a weird thing happens.... when I browse for about 10-15 mins, search engines like Google, Amazon, Yahoo do not display their results and the status bar goes blank. When i search on Live.com, it works fine but I don't know how, this spy ware gets into my systerm and most of the search engines do not display their results. Please help me as I depend on google most of the time.....by the way, i don't use any antispyware....forgot to tell.....also a window opens in the Internet explorer saying something like Antispywareexpert, Or Systemerror fixer .....please hlep

thanking you

Try working through the MRP:

After following the MRP (url posted above) if you think you're still infected with malware post a Hijackthis log in this forum.

I also suggest you install Windows Defender (if you use Windows XP), which is free and is available from http://www.microsoft.com/athome/security/spyware/software/default.mspx
