Lea,
Can you click on the little arrow at the beginning of each entry or the entry itself to get a more detailed description of what is trying to get into your system every few seconds?
Was this during the time you were at work and not using the computers?
Did you type those addresses in your search engine?
Lea,
Those addresses are related to Google. When you go to work do you shutdown your computer, put it in hibernate, or just sleep?
"find more information about my McAfee"
There you go! You can look at more specific types, and as I recall they have a web site that can be helpful.
It has been years since I have had any of their products, so I'm sure things have changed, and my memory about them has faded, except for the real PITA of getting all the bits and scraps out of my system.
I'm not bad mouthing them. All anti virus software likes to hold on forever.
You mentioned malware protection. Is it separate software in addition to your McAfee?
Have you run a deep virus scan lately or just the automatic quick scans?
I doubt if you will ever get all 3 meters to match. When you have done everything possible from your end to convince yourself that the problem is not on your end and compare it to the others having the same problem it will be decision time.
You might visit the Yak Shack. There are a lot of threads over there about the problem. You will see a number of familiar names and can pm them for anything specific. To paraphrase Gwalk, the more you learn about your system, the more you will be in charge of it, instead of it being in charge of you.
