download the free version and run the Quick Scan. If you can do this in Safe Mode with Networking (tap F8 on startup til the list with that name appears), even better.
I am having no trouble with Firefox either. The new version rocks!
I use this. I run it every week, and I am malware free.
I had the same problem as Anne, those redirected links are only after site hits.
As soon as malwarebytes was installed, I've had no problems.
