Problem - Thunderbird Gmail Norton

[harm_less]

I run Firefox, and Thunderbird for both my email accounts which includes Gmail. My antivirus and internet security is by ESET and I've never experienced anything like the issues SueDonim seems to be having. Based on my use of ESET AV for over 20 years (from memory) it is my recommendation to anyone requiring extremely effective internet protection with the minimum of bloatware.
