Thunderbird runs very slowly after latest round of 11 updates from Microsoft, restoring computer to earlier date fixes problem.
Thunderbird version 24.4.0 Windows 7 Professional Service Pack 1
Microsoft uploaded 11 new updates ( 7 updates for Windows 7 and 4 for Office 2010) on 9 April 2014. After automatically installing updates on my computer Thunderbird runs very slowly, i.e., every time anything is selected, Thunderbird give error "Thunderbird fails to response" which takes about 1 minute to clear. I restored computer to earlier date that did not have these updates and Thunderbird works OK.
Also updates changed default search engine in Firefox 28.0 from Google to Bing ! ! !

What is your anti-virus software?
1st of all, thanks for looking into this.
I use McAfee Special Edition from AOL.
It appears other folks are also having the same problem with the latest update from Microsoft.

The problem is McAfee.

Appears that you are right.
McAfee was running a scan continuously. I uninstalled it. Then ran all of the Microsoft updates. Finally I reinstalled McAfee and turned off real time scanning of e-mail.
Thunderbird appears to be working OK now.
Thanks for your help.
