    "I made a account jus to warn others about this program"

    August 4, 2012  |   By So_Honest


    There isn't any. ABSOLUTELY NONE.


    I already had avast and malwarebytes. Which are the best products I use for my Dell Windows 7 computer but I heard MSE is excellent too. TheAl12345 is absolutely right. MSE doesn't work well with other programs and froze my computer before it even finished downloading. I had to put my computer in safe mode and it still wouldn't uninstall. I restarted my computer, restarted my router, and eventually had to erase my original antivirus/ malware programs and shut all startup programs down to finally erase MSE. Also, after erased MSE my toolbar went back to basic which sucks but I fixed that by clicking on the desktop>personalize, and change themes. If you care about your computer DON'T download this garbage. Any positive reviews about this product are from people that work for Microsoft.


    MSE like most Microsoft products is garbage.

    MSE specificly IS NOT to be used with any other antivirus. In fact you should never have 2 antivirus products on the same computer, unless one has its realtime protection turned off. Even this is highly frowned upon by computer experts. When a antivirus causes problems when installing on a computer that already has an antivirus running,this is merely an indication that the antivirus being installed is a highly sensitive one that is trying to protect right from the get go!!

    I don't work for Microsoft and I am a former AVG user. I have this installed on 5 computers for over a year now and have had no problems or infections at all. Great product!!!!!!!!!!
