avast terrible in virii detect?!?!?!?

[Lisandro]

Is it really important if product A or B catches some obscure virus and product C doesn’t? I don't think so. Eventually, every major AV product will catch any global virus/worm threat. The question is, how soon, which is especially important in those days of so called blended threats. And what's the use of incremental updates if update process effectively disables AV product you are using, as it does with some of the products in the market. So, the focus should be on the response time, accuracy and robustness of the update process.
…and the ability to repair the damage!

Very good point of view
