I've got a single system here at the office that has been compromised with redirect malware. Not sure exactly which one it is, but most of the redirects point to "The Click Check" site. The browser is Firefox and I'm not sure if the problem exists in IE. So far, I've done the following: Scanned with Malwarebytes Anti-Malware and SuperAntiSpyware Scanned for virus with AVG and Kaspersky rescue CDs (no virus found) Used RKill, Combofix, and TDSSkiller Checked all proxy, DNS, etc. settings Checked the windows host file for bad entries Even after all that, the redirects are still occurring. My next step may be to completely remove Firefox, delete the user profile, and reinstall. I don't see any FF add-ons/extensions that could be the cause. I've had systems loaded with tons of viruses that are easier to clean than this. Any suggestions?
