Question

Q: Can MS Security Essentials work with another protection software?

I have two security software in my OS, Ms security essentials & Symantec endpoint.
Is this wrong?

Answer

A:

Yes. Having more than one antimalware program on a computer can cause conflicts, system instability, and performance issues. You should uninstall microsoft Security Essentials or Symantec Endpoint.

Answer

A:

Hi,

Two major antivirus programs should not be on the computer at the same time much less running. Even
the remnants can interfere and cause strange issues.

If you need to uninstall Symantec Endpoint :

==============

Here is what I use and recommend : (These are all Free versions and very effective.) 

Avast and Prevx have proven extremely reliable and compatible with everything I have
thrown at them. Microsoft Security Essentials and Prevx have also proven to be very
reliable and compatible. Use MSE and Prevx or Avast and Prevx however not all 3.

Avast Home Free - stop any shields you do not need except leave Standard, Web, and
Network running.

Prevx - Home - Free

Windows Firewall

Windows Defender (not needed if using MSE)

IE - Protected Mode

IE 8 - SmartScreen Filter ON  (IE 7 Phishing Filter)

I also have IE to always start with InPrivate Filter active if IE 8.
(You occasionally have to turn it temporarily off with the little Icon on LEFT of the + bottom
right of IE)

Two versions of Avast are available 6.x and 4.8x

Avast 6.x - Home - Free - Stop the Shields you do not use (except File, Web, Network, &
Behavior) - double click the Orange Icon in Notification Area - Real Time Shields - click the
Shield you want to stop - STOP. To stop the Orange Icon from showing an error indicator -
click the Orange Icon - Upper Right - Settings - click Status Bar - uncheck the Shields you
disabled - click OK

Avast 4.8x - Home - Free - stop any shields you do not need except leave Standard, Web,
and Network running. (Double Click Blue icon - details next to OK. - upper left Shields -
Terminate those you do not use.)

Or use Microsoft Security Essentials - Free
http://www.microsoft.com/Security_Essentials/

Prevx works well along side Avast or MSE

Prevx - Home - Free small, fast, exceptional CLOUD protection, works with other security
programs. This is a scanner only, VERY EFFECTIVE, if it finds something come back here
or use Google to see how to remove.

PCmag - Prevx - Editor'a Choice
http://www.pcmag.com/article2/0,2817,2346862,00.asp

Also get Malwarebytes - free - use as scanner only. If you ever suspect malware, and that
would be unsual with Avast and Prevx running except for an occasional low level cookie
(no big deal), UPDATE it and then run it as a scanner. I have many scanners and they
never find anything of note since I started using this setup.

Hope this helps.
