I don't share the paranoia of certain Americans, so I'm quite happy to continue with Kasperky, in fact, I just renewed six licenses with them, three Internet Security and three Total Security. I've used Kaspersky security software since it came on the UK market, which must be 15-20 years ago and never had any problems with it. I've met Eugene personally and respect his integrity.
I like the hourly check for signature updates (when I checked up, I was getting 6-8 updates a day).
But if you do have reservations, Trend Micro comes out very well in the magazine tests, that would be a good choice. But that's it really, your money, your choice.
