Norton Performance Alert - What does this mean?

Hello Community - I oftentimes on my laptop and a few times on my desktop receive a Norton alert in the bottom right-hand corner of my desktop.

 

It states the following:  Norton Performance Alert - High CPU Usage by Internet Explorer.

 

I was told that this means some malicious file is trying to download onto my hard drive.

 

How do I prevent this from happening and find out what is causing it or if I should be concerned.

 

Two weeks ago, my laptop was infected with the happili dot com virus which Nortons did not catch.  After a complete OS restore, it seems to be okay.

 

Thanks!

Hello Carmie5,

 

SendOfJive is right. He helped me several weeks ago after I started using the Chrome Browser. Chrome is a prime example of something using high cpu when it updates. It updates itself at any given time. I had to change my routine when turning my machine on. The very first thing I do is open Chrome and check for updates manually. This way if there is, I just let it run because I know it's going to use 100% cpu. This way also, I'm not usually interrupted during my computing day or night with high performance alerts.

 

During the update the pop out from the lower right tells me Chrome is using high cpu. I know this and just leave it alone and it slides back in. After, I relaunch Chrome to finish the update, then close it and restart my machine and everything is fine.

 

Nothing malicious, just a legitimate program updating. Myself, I have both Chrome and IE placed in the Program Exclusion list. Mainly when using either browser at You Tube or any other flash video or content. Otherwise a person might be getting performance alerts all the time because of flash. Nothing to worry about. As SendOfJive said, they are informational only.
