This is pertains to my home computer. It has been running Windows-7 and Thunderbirdfor over 2 years. I’ve been using McAfee for over a decade with no problems until the last update (last week) made my email software(Thunderbird) freeze and go “not responding”. Activity monitor showed McAfee took over all 4 of my 3GHZ processors to peak them at nearly 100%. What did McAfee just do? This has never happened before. There was no new emails (with viruses) and no new operating system software installs.
Please note: THERE WAS NOTHING WRONG WITH THUNDERBIRD OR THE OPERATING SYSTEM UNTIL McAFEE SAID TO REBOOT (after McAfee update) & WHEN I DID, IT IMMEDIATELY WENT TO HE** – so blaming it on Thunderbird or Microsoft is not a realistic solution.
Now I have to launch my McAfee control panel to disable REALTIME SCANNING so I can read my email. Last night I installed the “virtual technician” which indicated something was missing-corrupted and the “fix it” button did not “fix it” so I uninstalled and reinstalled McAfee – and that didn’t fix the problem either. Something in the last McAfee update certainly did this.
Any thoughts would be appreciated.
Thunderbird's latest version has a problem. Turn off Email attachment scanning in SecurityCenter > Virus and Spyware Protection > Real Time Scanning > Settings
You are still protected if you save said attachments to the hard drive, they will then be scanned.
This thread has some insight on that - https://community.mcafee.com/thread/50903?start=0&tstart=0
I've been having the same problem for about 2 weeks now. I thought it was TB but now realize it is McAfee. I tried to change the settings to exclude my emails, but the McAfee view page wouldn't allow me to click on "apply".....so the problem is still there. I'm reading that this issue had gone on for quite a few years now...at least since 2004.
