I reckon ALL the paid AV products are snake oil - I’ve used Microsoft’s Security Essentials on over 100 PCs now and I’ve seen not one virus on any of them.
If you intend to actively seek-out viruses (e.g. download pirated games etc.) it MIGHT be worth getting one of the big hitters like Kaspersky, simply because they are a bit more aggressive with the updates. For a regular PC user tho, they’re all a waste of money
and - indeed - to justify their cost they’re all bloated PC crippling shit too
p.s. if you never received EXE files from other people - never connect-up other peoples portable drives - never download ‘dodgy’ stuff, I’d actually say you don’t need an AV product at all tbh - and your system will go faster as a result
In just under 3 years this PC has produced just 3 virus alerts, all related to the files I keep on my ‘toolbox’ flashdrive which include some things like WGA removal tools and Windows Activation Tools (useful when the licence code has been scrubbed-off the base of laptops -honest!)
