I have the cash, so I want to buy a good virus checker - keyword "buy". So please, no pirate talk XD I've been looking at different product ratings online and in stores, but on the surface I can't really notice any selling points that put one virus checker above the other. I know people who use Norton and people who use Mcafee, and both seem to like the one they chose. A virus checker is all I really wanted, but one of these full system protection packages would be fine, too. I'm just not sure which one to buy. I recently tried out the free trial version of Kaspersky Internet Security (or at least I think it was) and the software pretty well killed my PC. I couldn't do anything while it was running (slowed everything to a snail crawl), and it took my PC at least 10 times longer than usual just to start up properly. I don't want something similar that's going to kill my system because I'll never actually have it turned on. So, any suggestions? I'm willing to pay a bit extra for the better product, but if most virus checkers are the same, which is the cheapest that doesn't sacrifice the quality?
