A word of warning too: if you ever get a call from someone claiming to be from Microsoft or whoever and claiming that they're "getting error meesages" from your computer and that it's infected with a virus which they can fix for you, just hang up. That's a scam. I tell them that I work for the FBI and that I put the virus there to catch people who scam other people by claiming to have "error messages" and they hang up pretty quickly.
