    Windows Defender

    Hello All :)
    Having read a new build of windows defender has been released i thought i might give it a shot (not that i've tried the old build, but...).
    But prior to installing it, i guess i might as well ask everyone who has it already installed (especially the new build), what is it memory usage (i believe it has 2 processes)?
    Thanks in advance, Adam.

    I never liked MSAS and Windows Defender doesn't fit in my plans for the future either. I don't have any good reason for this, but I don't like scanners in general and MSAS was never a big help for me.
    I use Ad-Aware and Spybot S&D, because they still remove the most 'popular' adware/spywares. (sorry for the word 'popular', I couldn't find a better one).
    I use ZeroSpyware, because it's an interesting AS scanner.
    I use SUPERAntiSpyware, because the author seems to make an extra effort to remove the more sophisticated spywares.

    Just recently upgraded from Defender Beta 1 to Defender Beta 2. Task Manager shows the following (numbers are rounded and estimated averages are shown if usage was varying moderately):

    Process: MsMpEng.exe

    8.1MB Memory usage during real time protection (background)
    8.8MB Memory usage during scanning

    11.2MB Virtual memory during real time protection (background)
    11.4MB Virtual memory during scanning

    Process: MSASCui.exe

    4.5MB Memory usage during real time protection (background)
    5.2MB Memory usage during scanning

    9.2MB Virtual Memory during real time protection (background)
    9.4MB Virtual Memory during scanning

    You've been a great help, Stallcup, Thanks :)

    * THE BIG EDIT *
    (which basically summarize all previous 4 edits).
    After some thinking, i've decided to put this product in the "scan-on-demand" group.
    Problem is, it insist on running its service even if real-time protection is disabled.
    So, my first instinct was to uninstall it (stupid instincts...).
    However, after some more thinking i realized i could just set it service to disabled and start it whenever i want to perform a scan, so i've reinstalled it.
    So at the moment, whenever i need to perform a scan i just start the "Windows Defender" and "Automtic Updates" (for updates, duh) services and disable them upon scan finish.
    A bit clumsy, but gets the work done!
