Avira has just released an updated version of its fleet of security products destined for desktop protection, bringing it to version 10. By far the most popular of the bunch is AntiVir Personal, which is also the most feature-stripped in Avira’s portfolio. It happens to be so popular because it falls under the freeware license. As its name suggests, the product can be employed with no restriction for personal use, while its adoption in corporate environment is strictly forbidden.

It does appear to be a rather seemless upgrade, have you updated to v10 and if so what have you concluded as pros or cons so far of the new version?

Sorry I can't help you. I don't, & haven't used this product.

What I'm confused about is that when you check version everything still shows version 9.0.0.422 and indicates that it is the full version untill 7/1/10. It seems to be working so far and have no problem with using full version, but will have to see what happens on July 1,. One thing that I don't like is that it indicates after a scan that there is one warning but you can't determine what the warning is about.
