I bought a laptop with McAfee antivirus .
Computer is running slow .
At first, I thought that the case in windows 8.1. Reinstall system and McAfee installed again. There was the same problem.
Reinstall all again. Download Avast , everything works fine.
Mcafee can't be disabled even for the time. It is very inconvenient antivirus.

Oh, I'm sorry
My computer was working slowly not because of McAfee antivirus.
The problem was in the drivers.
Please remove my report . I was wrong.
