I have an HP Envy laptop running Windows 8. I installed Avast Internet Security yesterday, and ever since, my iTunes will not open, or briefly open and then crash. I am incredibly frustrated, as I paid for 2 year of this Internet Security Software, but if it does not allow iTunes to run I will have to get rid of it. I can’t live without iTunes.
iTunes does open in safe mode, where all plugins are inactive, so I think it has something to do with Avast inserting itself into iTunes somehow? I cannot figure this out for the life of me, but it needs to be fixed. Thank you!
I used McAfee prior to avast, but my subscription ran out and I disliked how much memory/data McAfee used at a time, so I did not renew my subscription.
Under Settings>antivirus, I added all Apple files as exclusions. Additionally, I completely wiped my computer of iTunes/Apple programs by using this tutorial (https://discussions.apple.com/docs/DOC-6562#reinstall) and then reinstalled iTunes. Good as new again.
You also should remove everything from McAcrap.
Just uninstall from control panel will not do it. http://www.ache.nl > Malware? > remove (old) av > McAfee
