Of all the antivirus's installed, my personal vote is for avast now, been using the same for past one year and seems it is stabler and effective than Kaspersky. The auto update feature really keeps the software up to date with the Avast community IQ option. The software is so easy to use as well.
Ever since, I am only using avast as an antivirus. Well, I simply love the features and the one that you said, the auto update feature, yes I agree with you, it really keeps the software up to date.
Avast has a very clean user interface that is not bogged down with fancy graphics or large amount of menus. This is good because it makes it easy to navigate and also keeps the program loading times to minimum.
