I keep receiving a message on my comcast.net email, a message about my gmail.com beeing disabled and I have to enable it. The message disappears within seconds and reappear again and again. My gmail.com address works perfectly.
This is very disrupting. Any help ?
Run a scan of your system with your A/V software to see if it finds anything. It sounds like you have some kind of malware infection, or your email account has been compromised. Change your password and security question as a precaution.
