My mac, a G5 powermac, recently started going ape. When I open the email, it quits after about ten seconds. Also messages are rapidly self-replicating. I now have over 2,000 messages waiting to be sent to my inbox. How can I lick this problem and what may have caused it?

So you have messages waiting to go out on your inbox or outbox? a these messages unique or copies? what program as it? Use App Zapper to completelt get rid of this offending program. I don't think it's a virus because Mac don't tend to get them, if it is you can always use ClamXAV to quarantine and delete the possible virus.

Thanks for your response. The messages I am getting are copies of each other. Even ones that I was able to trash are coming back, sometimes as many as twenty or thirty of each one. I am using the program that came with my G5, the "stamp" icon at the bottom of my doc. I will get back with you if I have any more questions. Sincerely, Don

That's Apple Mail, and it sounds like it's broken on your Mac in a major way. You could uninstall it (completely with app zapper $10...or drag it to the trash..doesn't get rid of support files) or run Software Update (apple menu-->sofware update) to see if there is a bugfix. That is one of the many 1st party apps I don't use. Did you try ClamXAV yet? Did it find anything? I've never had a virus native to my Mac...I've only found one...a windows trojan in a virtual PC that had AVG antivirus and a large zip file that was a game i got for my ipod touch. There are virii/trojans out there for Macs but not the ocean of malware that lives on Windows PCs.
