I have Avast Pro 7.0 1426
iTunes Shop is being blocked. Apple Support says I should uninstall Antivirus program. If I do that can I re-install my Avast Pro?
Welcome to the forum.
What error message are you getting
What other security software are you running???
avast! scans it doesn't block unless it's infected.
What firewall are you using
The more information you give us the easier it is to solve your problem.
Uninstalling avast! is probably the last thing you should be doing.
