I tried to uninstall Avast Internet Security as I was unable to use its firewall. ( By the way, I use Windows 7) After having tried unsuccessfully to get the firewall to work I was advised to uninstall the current version, and re-install Avast Internet Security again. However, it won't let me re-install because it says that there still is a corrupted Avast Internet Security software on my PC. Would someone be able to help me please. I am really quite concerned as I am not that computer literate and worried about leaving my computer exposed.
I would greatly appreciate some help with this.
