Windows 7 Is 3 scanners too much?

[CJ12]

Hi,
Please, I have Kapersky Internet Security 2012, Malwarebytes Anti-Malware Pro and Windows Defender installed and I scan regularly with all three respectively.
Is this too many scanner programs? I am worried there may be conflicts between the programs which will leave my computer more vulnerable than if I just had one scanner/shield program (or even just two).
Can anyone suggest a solution which will 1) save me time, money and CPU resources and 2) leave my computer as good as, or better, protected?
Thanks in advance.

You only need one real time AV scanner and more than one running at a time can cause conflicts tho this is less likely to be a problem with AV scanners than with firewalls which you should certainly never have more than one of. It is useful though to run a regular AV scan to try and catch anything which may have crept thru the real time scanner.

Thanks. I will uninstall Windows Defender.
