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.
