I agree. In the past few days I've reviewed lots of support topics of the past few months. In almost every case where the person has McAfee installed IT has been the cause of slowness. If you intend to stay with Thunderbird you will want to look at that wiki reference from christ1

https://wiki.mozilla.org/Thunderbird:Testing:Antivirus_Related_Performance_Issues#McAfee does not necessarily involve turning *off* McAfee. It first suggests disabling a feature of McAfee that is frankly not needed and known to cause issues. And also suggests how to ensure that McAfee is not scanning Thunderbird directories, which it is NOT supposed to do, and has been broken serveral times over the years.
