Windows Defender and McAfee Total Protection compatible?

Jump to solution

I keep getting a message that Windows Defender needs to scan my computer and am not sure what to do.  I have current subscription to McAfee Total Protection and I do not know where windows defender came from.  It (windows defender ) is updated by MS a lot and it keeps wanting me to use it to scan.  I already have my system scanned by McAfee regularly.  OS is windows 7 Prof.

Does anyone know what Windows Defender is, did it come with Widows7?  Is there a problem having it with McAfee Total Protection?  Do I need to get rid of it and, if so, how? how do I get it off or disable it?

Thanks!

              Windows Defender Anti-Spyware is compatible with McAfee. As long as you are running Windows 7 Sp1. However, make certain you do not have Microsoft Security Essentials running as well. For the (RTS) Real Time Scan module will clash /conflict with McAfee.

                You can go ahead and (Allow) Windows Defender to scan. Simply make certain it is not scheduled to do so at a time when McAfee is set to scan also.

                   I failed to mention that (Windows Defender) is part of Windows in itself. This is why you seen it on your system.

All the Best,

Hi forum,

As long as Real-time scanning is turned off, while you are scanning with Windows Defender, you will be fine and Windows Defender will finish faster. I run with Real-time Scanning is set to Never and got no Viruses. However, I do have the McAfee Firewall always on and set to Monitor.

I don't recommend turning real-time scanning off on a permanent basis as that would mean McAfee is not checking anything at all, nor is it necessary, I find no issues at all running Windows Defender alongside in XP (if manually installed), Vista and Windows 7.


*Exception:  In Windows 8/8.1, Windows Defender is not the same in those OS's as it contains  anti-virus and therefore must NOT be run alongside a 3rd party anti-virus such as McAfee as the two will clash and possibly allow infection in.   It should not be activated at all in 8/8.1 for any reason as long as any 3rd party anti-virus is installed.

In Vista and Windows 7 the installation of McAfee will auto-disable WD as a precaution.  It's OK the reactivate it in those systems as it is not an anti-virus.

Thanks Peter, I failed to mention that WD is also compatible with XP/Vista. The reason I stated as long as one is running Windows 7 Sp1, was as you clearly stated. In Windows 8/8.1 WD has Anti-Virus Capabilities...Which will indeed conflict/clash with McAfee.

In other words, the OP stated he was running Windows 7 Professional.

I hope you're reassured by those responses. I too say there's no problem with running Windows Defender alongside McAfee on a Windows 7 machine. They are quite compatible. Windows Defender needs regular definition updates so it can always look for the latest threats, just as McAfee needs them. That's not a problem.

Windows Defender is a genuine Microsoft program, and it comes with Windows 7. It watches for spyware and low-grade threats, but deliberately doesn't do viruses and other high-grade threats, leaving those to dedicated antivirus programs from Microsoft and all the other vendors. It also particularly guards against changes to Windows settings, and when it does a scan it concentrates on those areas relevant to Windows. As a product it's quite useful to have - it's lightweight, mostly unobtrusive,.efficient and above all it comes from a known and trusted source and is safe to run.

I see no reason to panic about it or to try to remove it. One day it might detect and block something and save you a bit of trouble, but in the meantime it just sits there and quietly does its job. Far less demanding than McAfee

Thanks to Hayton, catdaddy, Ex_Brit and thecreator for your helpful responses and the very useful information.  I read all carefully and will not turn real time scanning off.   I did a search on my c drive and did not find MS Security Essentials and also checked the program folders.  Only Windows Defender was there (and McAfee of course).  Much appreciated, and yes, I am very reassured.
