I have installed an Avast Internet Security on my windows 7 computer system and i have recently updated it. Actually i wanted to download one software because of which i need to disable the shields temporarily. Now as i have disabled it on my machine and when i reboot my machine then it says that my system is not fully secured, and three of the shields are still switched off. I know that but when press button to turn them ON then it does not works. What to do now? How can i fix this issue and is there anybody having the same issue?
