How to Fix Error 421 4.7.0 Occurs on Norton antivirus?
« on: April 05, 2016, 11:52:50 AM »
Hello Friends…

I am using HP desktop at home which is running well and I have installed the Norton antivirus application on the system before some days.

But unfortunately from a few days when I try to run the antivirus app it shows a error code 421 4.7.0 and some active programs start freezing and crashing.

It’s quite unfortunate for me because I have no idea how to fix the error code 4214.7.0 on Norton antivirus app.

Please help…
