I think I've been infected with a virus and my other anti-virus program isn't catching it; how do I turn on Firefox's virus protection?

For the past few months, I've had this very weird problem. Any time I'm online, what looks like a big cursor (as if I'm in a writing program or typing in a text field) will appear in random places on any webpage. The cursor flashes, can be different sizes, and comes and goes randomly. Sometimes it's almost three-quarters the height of the webpage; sometimes it's small. I mentioned it to a computer-savvy friend who suggested that the computer might be infected with a virus. I have Avira, but apparently it's not catching this virus, if that's what it is. How do I know whether Firefox's anti-virus program is enabled, and do you think it can solve my "cursor" issue?? Help!

Firefox doesn't come with an anti-virus application, as other web browsers don't.

There are specialized forums where you should be able to get help with that issue: 

   * SWI Forums - http://www.spywareinfoforum.com/
   * Safer Networking Forums - http://forums.spybot.info/
   * Bleeping Computer Forums  - http://www.bleepingcomputer.com/forums/

You may have switched on caret browsing: press F7 to toggle

See http://kb.mozillazine.org/Scrolling_with_arrow_keys_no_longer_works
