JohnnyT,
one other thing I like and I have mentioned it before on AZ for those who are having problems with their computer and need help, (as I have used them several times now), is go to
http://www.geekstogo.com and click on their Technical Forums. There, they give you a list of items to check to see if you have malware on your computer.
Also, I use their free version of AVG software. This is a anti virus program that I feel actually works better than SpyBot and gives less ads of them wanting you to puchase the full version. Also has email scanner built in.
If you post a problem with your computer, they have a search program called HighJack This. You load this, post it in the forum and one of the technicians will come on and solve all your problems and get the computer running like new again. This program actually lists all the problems in the registry and by seeing this list, the tech can discover where your problems are located.
It is a little lengthy process because there are some many using the forum, but, well worth the wait. And, the other great thing, is it is
FREE.....
