Or buy Norton as well...Those two are well known for not being reliable in catching virus as well as the two most virus malware attacked software. That should lead one to rethink of getting either one. It all comes down to common sense in what people click without thinking ahead of time or opening on the web. I use A/V that is free and it works and I can get updates without having to constantly spend money every year to subscribe to it-granted the free version has its limits but then again people show know how to use the internet and protect themselves besides using the software. The software is only as good as the programmers and how fast they can keep up with virus malware programs coming online. It's worse if well known A/V software will be the most targeted for bugs where they can exploit. They are less likely to target lesser known software cause they can do the most damages or cause problems on software that is more widely used.
