Email and cpu usage issues

[blackhawkcre]

I noticed a few days ago my verizon droid 2 global would show me emails then after I viewed them and cleared them they would download again like they wer new. It started first with one aol account, then a day later with a second aol account, now it is happening with all of my email accounts. I also noticed the task manager has some strange apps running at high cpu consumption (data collector service, email authenticator &suggestions poll scheduler service) . I tried reboots including taking the battery out. Any ideas of what this could be and/or a potential fix?
