Kaspershy Internet Security is what I bought to run. I've used many different ones in the past but I like this the best. I also use the FREE Ewido Anti-Spyware.
BitDefender security 10, but it has several quirks. Do not know how long I can put up with it.
When I instaaled it it said that it had to sisable Microsofts firewall, which it did . But shortly thereafter an MS security update re-enabled the MS firewall, and you can no longer disable it. Ever since that I have had some problems with Bitdefender.
I imagine others also have have some problems with BitDefenders.
moen
for XP, I always used NOD 32 and Sygate firewall;
with vista, I am using MS One Care, and the built in windows firewall..
Behind a NAT router of course...
user needs - Sorry to hear about your problem, but happy to see you switched to Kaspersky! Since I've been running Kaspersky I have had no problems and have not looked back.
