In the second case I have problems with updating metro applications, which updates can not be installed without starting the Windows Firewall service.I think this is a big problem for the ordinary user.Viber metro apps stop working and crash after a few seconds.All metro apps work normally only if I uninstall Kaspersky Internet Security 2015 or when I stop the Windows Firewall service in Windows service with Kaspersky Internet Security 2015 installed.I downloaded Kaspersky 2015 (and 2016) and tried installing them but got blocked by Error Message 2016 - when I followed the string to solve that, Microsoft sent me to the Fixit application, but I learned that Fixit doesn't yet work with Windows 2010, so all of Microsoft's hype about thorough testing, yada, yada, yada wasn't correct.I removed Windows 10 and went back to Windows 7 and Kaspersky.Thanks, MM Hi there; I forgot to have mention that I have done a reboot before my personal files are kept but every program has been removed;; which was around may 30th to first week of june; When I redownloaded kaspersky I believe it was the 2016 I\m not sure if my drivers are making it crash?Make sure your Windows 10 has all the latest updates installed might fix the IRQL NOT LESS OR EQUAL error.
