My computer is a Dell Inspiron 620 running Windows 7 Professional. 64-bit. I have ZoneAlarm Security Suite, which does daily virus scans, and Webroot SpySweeper, which does a daily scan for spyware. Neither has found any virus or threatening spyware (just cookies I could delete myself). I keep running various deep scans, including Malwarebytes, TDSS Killer and BitDefender Removal Tool TDSS TDL4, and no malware shows up. I've cleared cookies, cache, etc. and restarted.
I made a new desktop shortcut, which helped for a couple of times opening Firefox, then the problem came back.
I downloaded and ran Revo Uninstaller in Advanced setting, then reinstalled Firefox. Helped a couple of times, then the problem came back.
I checked the Firefox help link. No programs are set to use Firefox. I deleted mimeTypes.rdf according to the directions, then restarted Firefox. Same problem remains.
I've completely cleared history, but after once or twice opening Firefox, the problem returns. I've restarted my computer after the above.
