Has anyone put on ((Microsoft Security Essentials))?
They started that over a year ago and it's FREE. It's a virus protector that works very well. This is all I have been using for the last year on both computers. Every once in awhile I click on something that I probably shouldn't have. But you never know what's gonna happen when you click on anything because there are a lot od idiots that put nasty crap on. This MSE's catches it before it becomes a problem. I talked with a geek guy and he said that MSE's is the best thing that they have done. Your computer will slow down while it scans and does an update, but does not affect it when it's not doing it's thing.
Check it out. Like I say, it's free and does work well.
Go to google and type it in and do what it tells you to do.
