First timer here. Before I found out I wasn't supposed to run ComboFix (yet), I did--and it worked. No more Google redirect virus. Many thanks. My browser is still being a little tempermental, which may just be from changes in security settings, but I'm going to follow up on the malware topic area just to make sure.
PS: If I didn't post the correct way, cut me some slack. I don't usually do these, and although I'm a software professional, I'm a dinosaur. I'd have to study my cell phone before I could do a text message, but I have been known to reverse-engineer binary files.
