    MSE is a very good antivirus; I used it on my old notebook with Windows XP and now I use it on my new notebook with Windows 7. It is light and effective, and consider that I visit all sorts of sites and download and test all sorts of software. MSE never failed to warn me of potential/real viruses and malwares.
    I just added a (free) tool that makes bi-directional the native firewall that is included in Windows. Regards.

    Poor detection and removal. Slows your computer down far too much as it scans every program you open
