Hello Bruce, I use Norton's. You buy it, put it on your computer and let it automatically run a check. My copy does a check every time that I start-up and automatically catches the virus or worms as they come in over the e-mails- A large warning shows up on screen and asks if it should repair the file or delete it. I let it repair worms and destroy viruses. I hope this helps Bern.....Peace [log in to unmask] http://members.chello.at/bernard.shaw/poetry.html http://www.postpoems.com/members/bern/
