Wow! Aren't you special?
Answer this then, special boyo....if MSSE is so damned good, why is it continually outclassed in testing by the likes of ESET, Kaspersky, G Data, F-Secure, AVIRA (paid version, not the free version) done by such sites as AV Comparatives? MSSE always finishes a class down from the aforementioned group of pay-for AV suites in a wide variety of testing.
And as for other free AV software, none fares well in testing compared to the pay-for AV software. After all, as in the case of AVAST which has a free version as well as several pay-for versions, why would the free version work as well as the ones you pay for? The makers of AVAST aren't completely stupid and it wouldn't be in their best interest to have their free version work as well as the commercial versions of their software. If it did, no one would pay for the commercial versions. Thankfully for us that have been repairing computers for the last few decades, dependence on free AV software gives us a steady stream of income as the limitations of the free AV software get exposed on a daily basis.
[edit] Oh yea, "Antivirus fanbois" LMFAO! What will they think of next?
But I'm sure you know better.....after all, you've been building computers since there were rocks, right?
