This is the error that started happening 6/29/09, for ONLY ONE USER, and re-occurs every 8 minutes (EXACTLY 8 minutes). We are using SEP 11 MR1 MP4 (something like that), and it has found no virus on her PC. I also puled her HDD and scanned with Avira, Malwarebytes and F-Secure, all come up with nothing. I also manually searched for viruses and could not find any.
The domain has not been blacklisted, which tells me there is no virus, and there is something else i'm missing. Im running out of ideas. The end-user says they are not sending out mass e-mails, and checking the tracking database, he/she is correct.
The error is below (remember, this repeats every 8 minutes (to the second) from the time she logs in, to the time she leaves.
