Mail producing +100% CPU usage

[montycat]

Hi all, after using Google and MRoogle I still haven't found a solution for this.
Mail CPU usage spikes to over 100% and the MBP gets extremely hot. I then have to force quit Mail. I am using MobileMe and all the lastest updates for Snow Leopard. Thanks, MC

It could be....dare I say it...a virus! :O
I've heard of programs that take up 90% of the CPU for no reason...maybe that's it?

Does Mail give you a crash report?

Delete ~/Library/Preferences/com.apple.mail.plist.

Delete ~/Library/Preferences/com.apple.mail.plist.

Thanks, this is something I tried. It still didn't fix it. I deleted the Mail application and reinstalled it. It seems to be back to normal for the time being. I hope it stays that way!
