With Windows Vista / older PC is definitely not recommended

But: McAfee has made my PC into a lame duck. (My PC is not young anymore, but I have had to install McAfee never cause for complaint.) Meanwhile, I have the real-time scanning and automatic update scanning off !! However, the program de facto can not be disabled. It is still active after every time the PC, check the status, complains that the real-time scanning is disabled, mule, when the last update is more than 5 days ago, etc. McAfee spreads itself like a virus on my PC and has throughout his hands in the game - and you'll be slower. The e-mail program often depends on (although I have disabled the e-mail option in McAfee), the PC performance is eaten especially in the first few minutes after start-up, shutdown often takes several minutes surfing (. even though I have turned off also here the relevant options) takes longer my recent upgrade to DSL16000 I could have saved me - surfing is now slowly than before. And as a first real-time tests were activated, I was to "old times" remembers when I was surfing with a 28.8 modem via the analog telephone line.

The operation of the program itself is very sluggish. Often, it takes 1 to 2 minutes until it is opened and every action must be considered with a lot of time.

CONCLUSION: All options are enabled, McAfee sets my PC lame largely. A reasonable work is no longer possible. But even after turning off all automatic functions, annoying the program and makes the PC noticeably slower.
