Yes, it was through reading here while installing that led to my turning everything back to as it was. However, if a user has been using Thunderbird, and changes back, Avast needs to get restarted on the mail client to recognize that it has been done. Turning off/on the mail scanner does it in a second, as mentioned. Running very well, just as before. Getting close to purchase, especially now that Soulseek is covered in there, and that is what my mail scanning is for (hence the heavy viruses). When this goes final, I think I'll be ready to finally upgrade to Professional.
