“Can Microsoft Security Essentials co-exist with other antivirus software like McAfee or Norton?  Or do I have to uninstall my current McAfee Suite?”

Yes, you should uninstall McAfee Suite before installing Microsoft Security Essentials.

Microsoft Security Essentials is free software that helps protect against viruses, spyware, worms, and other malware or unwanted software. If you use Microsoft Security Essentials, you don't need to install any other antivirus or antispyware software.

In fact, if you run more than one antivirus or antispyware program at once, it might affect your computer's performance. For more information, see Uninstalling existing antivirus or antispyware programs before installing Microsoft Security Essentials.

Bottom line? You should choose one antivirus program. Obviously, we recommend Microsoft Security Essentials, but we’re not alone: others recommend it too.

  • The problem with microsoft security is that there is no customer support.  My internet provider provides me with anti-virus and malware protection.  If I have a problem, one phone call and the problem is solved.

  • I hope Microsoft has a big flashing red warning sign about these created problems before this program get downloaded.

  • What about Defender, and Malware you support. I could not get my Defender to work, after installing MSE.

  • I tried using Avast installed before Installing MS Security Essentials and it caused problems. I uninstalled Avast and that fixed the problem. Now I am going to uninstall Ad-Aware. Hopefully, MS SE will keep the viruses and other malware at bay.

  • Does the I.E.-9 update automatically install Microsoft Security Essentials? How do you choose not to have or to uninstall Microsoft Security Essentials?

  • Is Microsoft Malicious Software Removal Tool unneeded therefore if you have MSE installed?

  • Is the "Microsoft Security Essentials" free, or is there a charge?

  • I have replaced my anti-virus software with Microsoft Security Essentials and now have the 'XP Security 2012' virus :-(

  • why is my microsoft essentials allways turned off when i put my laptop on thanks
