I rarely opt for the paid for Anti Virus products but this is well worth using over AVG or NOD32.
1) Its a doddle to install, a complete novice couldnt go wrong 2) Its very unobtrusive, tells you what issues there are when they need attention and thats it. It just sits there protecting the system. 3) Effective, this picks up threats that have previously been overlooked by AVG! 4) You wont notice it running! Unless you run a dinosaur of a PC you wont notice any lack of performance (I actually installed this on an old P3 machine which was pretty slow to start with and it was still very light!)
With blended attacks and constant new trojans and viruses its time to ditch the free protection and get some serious security on your PC!
