UNINSTALL IT NOW!!! HURRY BEFORE IT'S TOO LATE!!
I had to reinstall my windows including all supporting softwares for hours because of screwed that caused by NAV 2022.
I couldn't run my Tiny Personal Firewall since I install NAV 2002. I even had ever think to buy subscription for NAV once.
Now, I'm using
AVG Antivirus as recommended by some people... it updates the virus database everyday and it's totally FREE!

It was catch the virus in my email once. Give it a try...
