Not sure if these problems are related, but here are the problems I have on my Win 7 system with Norton 360 fully updated. About a month ago I received frequent "High CPU Usage" messages referencing "Google Chrome" or "Host Process For Windows Services". These continue to this day even though I do not have Google Chrome downloaded on my system, and I don't know what "Host Process" is.
Last week I got two Norton 360 messages, "System infected: Trojan.adclicker activity" followed by Trojan.powerlik activity". I ran Norton Power Eraser, but messages came back. I did a review on the web re. these trojans, but am not competent enough to try the one solution that seems to work. I assumed Norton would come up with a solution and automatically download it to my machine, and a few days later I did find a Norton screen on my machine which said to restart the computer to eliminate some problem. I thought this resolved the issue
Yesterday I kept getting popups referencing a "Web Page Error: Do You Want To debug this Web Page" on almost every new page I brought up on the web. There was no identifier of where this error message was coming from so I believed it was a virus designed to get me to download more malware. I Xed out each time it came up. Today I am getting both the popup and the System Infected messages, and my machine has slowed to a crawl.
How deep is the doo doo I am in and is there anything I can do to correct it? I am using someone elses computer for this message so my responses may be slow.
Thanks.
