The procedure to shut off real time scanning of emails is as follows: Open McAfee Security Center. Click on navigation at the top right, then click on Features in the window that opens up. Then click on Real-Time Scanning. Then click on settings. In the drop down window that opens up un-check Email attachments and click apply. Then close everything up.

McAfee

McAfee has had major problems with Thunderbird, causing crashes and poor performance, "Not Responding", "Unresponsive Script", and other issues. For example [31], [32], [33], [34], [35], [36], [37], (in 2013), [38], [39], [40], [41], [42], [43], (perhaps), [44],

bug 592303. We recommend you do all of the following:

• Disable/delete McAfee Anti-Spam Thunderbird Extension in Tools | Add-ons | Extensions (It is safe to remove the add-on, and is absolutely not needed to have excellent virus protection.)
• Disable email attachment scanning (it individually scans all emails which slows down Thunderbird) - Uncheck Email attachments under Real Time Scanning > Settings > Scan these attachments and locations
• Disable scanning of Thunderbird files and folders (by default McAfee is NOT supposed to scan them):
  1. Right click on systray icon
  2. "On-Access Scan properties ..."
  3. "All processes", "Exclusions"
  4. "Exclusions ..."
  5. Add the "Thunderbird" and "Thunderbird Profile" folders and subfolders. Folder names must finish with a backslash. NOTE, if you have customized profile or account locations for mail, then you must exclude your custom locations.
• Please write/Call McAfee support to inform them of your difficulty. They can't fix what they do not know about.

If nothing else helps, then you may need to remove McAfee using the McAfee Consumer Products Removal tool, and seek different antivirus software.

NOTES:

• The above changes disable various features, but you ARE still protected from viruses by McAfee's other protection features. (quote from McAfee) "you do not need to worry, as [when] the Real Time Scan is turned on [which it is by default] it will scan all the files and attachments and will alert you if there is any infection."
• Common question: Thunderbird has worked fine for years, with antivirus (AV) product X. So isn't my new problem in a bug Thunderbird? Answer: No, typically not. Antivirus and firewall products are often tightly linked to little details in the software it is monitoring (eg Thunderbird), and which makes them susceptible to breakage or incompatibility from Thunderbird updates. It is the vendor of product X who bears responsibility to fix the problem in such cases.

Installation issue - If thunderbird update fails and you get a 7-Zip Access Denied error when downloading a new version or updating and you are using McAfee VirusScan Enterprise + AntiSpyware Enterprise 8.8, see the advice in this thread.
