Previously I had Kaspersky, which ran quite smoothly in the background. No delays at the computer noticeably. At the end of the period of use I had then but decided on the well rated McAfee, also because of the human price. Meanwhile, I'm on the verge of the McAfee runterzuschmeissen far before the end of the subscription and again spending money on another scanner. The McAfee brakes especially when you click printing capabilities greatly. As you notice it at least extremely. Until the dialog box for printing rises, go Felt 5-10 Sekunden rum. The pressure starts also felt later. Remedy was then disabling spyware real-time scan and the Active Protection to direct defense. Since then, the work misses the PC, printing is possible without commemorative break. The websites advisor I also disabled, which also slowed down often. I am satisfied by no longer, I must runterschrauben security purpose. But what always is a bit overkill, the multiple to be closed the week rather large message window, which the McAfee degrees so sees fit (Updates ..) or has done. I have no way to disable these warnings found. Since disabling the strong braking options me is the McAfee but several times a day with information windows on the cookie that I should put on the handbrake firmly gscheit again. Although I have options to select the depth and scope of protection, but not an option that protects me from this patronizing Hinweiswut the scanner. I actually like the McAfee even never.
