Norton 8506, 421 --Lenovo

I've had Norton products for years and a Lenovo ThinkPad E430 for several years. For the last couple of months, I've received N Error 8506, 421 errors. I've tried all the suggestions and finally stumbled across the following information:

 

"One cause of this error is a known issue with the Instant Reset utility distributed on some Lenovo laptops. Symantec recommends not to install Norton products on Lenovo laptops with Instant Reset utility. If you are encountering this error on a computer other than Lenovo laptop with Instant Reset, follow the steps in the article.

In many cases, this error can be fixed by restarting the computer. If the problem persists even after you restart the computer, you need to uninstall and reinstall your Norton product. Download and run the Norton Removal Tool to uninstall your product."

 

Really? N360 has worked fine until the last few months  -- and now I'm being told not to install it?
