Activity Monitor
Hello Friends.
My question is the following. I am experiencing screen freezing or lack of responding to commands with my MacBook Pro. I tried to find the reason. In the Utilities I went to Activity Monitor to check CPU usage. I found that ther is a process named AntiVirus, which takes about 125MB from Intel. As I am aware that apple does not need any antivirus, I decided to quit the process. When I tried to do so, I got the following message: "The process “AntiVirus” is owned by root. To quit the process, you must enter an administrator password." I don't know who the "root" is and what will happen if I quit the process. And why on earth should there be an Antivirus process if I use none? Please help me with your suggestions to solve the problem.
P.S. As an addendum, I'd like to mention that I used to have a Mackeeper on my Mac (it was many months ago). Then I deleted it from the applications. Maybe the AntiVIrus process is the "offspring" of the Mackeeper, which I deleted?
MacBook Pro, Mac OS X (10.6.8)
