I have both Norton Internet Security and MS Security Essentials.

I have a Dell All in One 2320.  I had Updated to Win 10 in June 2016 (?).  In January 2018 Win 10 would no longer work on my Dell.  I took it to Microsoft Store and they had to uninstall Win 10 and take me back to my original Win 7.  In the process I lost some of my programs and gained some that had originally come with the purchase of my Dell.  Anyway I had to reinstall Norton (Internet) Security (version last install/activity by Symantec 8/19/2018).  I noticed that I now/also have Microsoft Security Essentials (version installed on 1/25/2018) that updates definitions automatically every few days.  I keep my Norton up to date with scans etc, but don't really touch MS Security Essentials.  My question:  should I get rid of MS Sec Essentials?  Or is it okay to run both?  I'd rather just keep my Norton product, as I have found it to be better than other security products.  Please advise. PS I also run IE 11 and Google/Chrome.  I am an older retired widow, so I am by no means a computer wiz!!  Any basic help would be greatly appreciated.  Thank you.  Ruth L.

Re: I have both Norton Internet Security and MS Security Essentials.

Hi rwood1948:

Users are always advised not to run more than one antivirus program at the same time, since the overlap in protection can cause conflicts if both security programs try to compete for the same Windows resources and/or perform actions like removal of detected malware at the same time.  See the Norton support article Problems Running Multiple Security Products for further information.  One antivirus like Norton Internet Security (NIS) that runs in real-time protection mode (i.e., that starts protecting your computer as soon as your computer boots up) to detect higher-risk malware like viruses, trojans, etc. and one reputable on-demand anti-malware scanner like Malwarebytes Free that you can use to run the occasional manual scan for lower-risk PUPs (potentially unwanted programs) like browsers hijackers and adware should be sufficient for most users.

If you want to keep NIS then uninstall Microsoft Security Essentials (MSE) from Control Panel | Programs and Features.  Re-boot your computer after MSE is uninstalled and then download the MSE Removal Tool (the MS Fix IT Tool 50692 for MSE v2 and higher) from https://www.bleepingcomputer.com/download/microsoft-security-essentials-removal-tool/ and run this utility to remove the last traces of MSE off your computer.
