Hi there, can someone help me out here? I'm using Windows XP. There's something on my system that is tracking what I type. When I do a google search, I'll sometimes get a popup window (not via google) that displaying some results. Recently I've had a lot of pop up ads when I get online (properties show ibis in the path), some IE errors, and the icons of my shortcut bar have been all switched around. I downloaded AVG 6.0 Anti Virus System for free off the internet and found 'Trojan horse Dropper.Siboco.B' & 'Trojan horse Downloader.Siboco.B' & 'Trojan horse Downloader.Qdown.C' all of which were reported as 'Healed OK' after they were detected. There were 14 files (including a windows\system32\config file) that the AVG couldn't open and didn't check. Any ideas what I can do? Any help would be GREATLY appreciated, thanks!

yes, go to www.housecall.antivirus.com and do an online scan. Delete all that it finds. When all is said and done More is said than done..

Hi, thanks for the response. I downloaded Housecall from TrendMicro's site and had it run a scan on my system. It found a trojan horse downloader SIBOCO.B in my temp folder. I deleted it, but am still having custom search result page and ad pages popup. Any ideas on what I might be able to try next? Thanks!
