Every time I click on an email to open and read in Thunderbird Portable or when I open a new tab or link in Firefox, the programs crash. I tried changing my scanning settings on Avast as one thread suggested, but that didn't help. So I tried booting up in Safe Mode with Networking as another thread suggested and Thunderbird and FireFox now work perfectly. How do I get these applications to begin working again outside of Safe Mode?

Besides disabling Avast in the Main Settings of the Mail Shield, did you disable the SSL scanning component? There are quite a few steps to completely disable Avast interference in email:

Hi sfhowes, Yes I did disable the SSL scanning component. No change. The crashes seem to happen when loading the emails that have more content than just text. I have the option to block remote content, but the messages that have images seem to be the most problematic.

There may be another program besides Avast that runs at startup and is disabled in Windows safe mode; run msconfig (Windows key+R, type msconfig.exe) and check the Startup tab.

It could also be that even if all Avast actions on email are disabled, it still affects the email program itself when it is a portable rather than normal installation. If this is the case, perhaps adding TB and FF as Exclusions is necessary.
