    I wanted to try Avast more thoroughly but it wouldn't install on my system ... some driver conflict I suppose ... I uninstalled 6 other programs to see if it would help but I kept getting a reset towards the finalization of the installation process so I gave up after a couple of hours. I did try it a bit in my VM and that is why I wanted to try it on my main system and I liked it. I was mainly interested in its sandboxing capabilities because I'm searching for an good alternative to Sandboxie, Bufferzone, and Comodo's sandbox. MSE is good for people that don't want to be involved in what is quarantined but I like to be involved in the decision and I think MSE removes the questionable item without asking you.

    very good stuff, CyberDoc999 I use to use Avira but I think they went down hill, and switch to Avast free, But as far as I'm concerned the best one out on the market today is M.S.E http://www.microsoft.com/security_essentials/

    I have seen avast fail to block a virus
    Avira blocked the same virus on another computer

    This thing is Fast & Light on Resources! I have an Atom CPU & this is barely noticeable. I run games such as Halo & Left4Dead2 with no problems. I installed Malwarebytes before this as I was going to run without an antivirus software due to the fear of bottle necking my CPU. Malwarebytes was CPU Intense and noticable slowed my system! Avast has a good detection rate of spyware. People misuse the term Malware. Viruses, Spyware, Trojans & Rootkits are now Generalized as MALWARE. The detection rate & resource usage of this make it a top choice. A/V Comparatives thought so! I agree.

    Since version 5 Avast officially also uses heuristic technology (behavioral shield)!

    Well I have been using Avast for nearly five years and it is the best.

    It has a lot of features and a good detection rate and is the only antivirus that I really trust. Install Avast and your PC will be like a safe.
