I tried to download a few free anti-virus programs, but could never get thru their busy or otherwise screwey servers, and got to thinking, if I can't even download the thing, how much faith can I put in trying to download updates? Especially since one of them was from across the ocean.
So, after my mcafee could not be updated anymore, it was 2 years old, I found Trend PC-illin at Staples, in a staples wrapper, for $20 and figured, gee, its guaranteed in that if I get a virus, I could, if I wanted, haul the box off to the nearest Staples, and they will fix things up for free.
I am really impressed with Trend PCillin, it does an automatic update just about every other to 3rd day.
I figured, man, $20 is a lot less hassle then betting on some free anti-virus from cyber-somewhere and possibly screwing up my computer with a virus. And, the $40 mcafee and $50 norton didn't have any local staples guarantee.
