Looks like I have been infected by a hijack virus/trojan. When clicking on links in google searches, or links in pages being viewed the browser is directed to places like heavy.com, nextag, megasearch, etc. In viewing other threads I attempted quite a few of the fixes recommended for those folks. - Removed all spurious software, in control panel -> add or remove programs or windows components. - Installed and ran AVG 8 - removed google toolbar, yahoo toolbar - Attempted to run a number of the online scanners (Kapersky, bitdefender, pandasecurity), all fail to either download the virus databases, or when they do run they fail and indicate to try again. It's like they cannot communicate with their mother ships to download the software and definition libraries. Next I downloaded hijackthis and combofix. Ran both and have attached the logfiles to this thread. Any help would be appreciated.
