In your opening post you describe the issues you are having, but do not state how long ago these characteristics started prior to Aug 6, or if it correlates to installing or removing any program(s).
What were you running/using prior to this?FYI- I am running McAfee virus and firewall software provided by my ISP, Cox Communications.
Personally I am not very fond of McAfee as it has caused me more issues than resolved.
