Possible malware using computer's email - No threats found
When receiving spam, I have systematically just marked/reported as spam using my email app, and then deleted the spam. Yesterday, when I tried to mark/report a couple of spam emails, my email/ISP app reported that it wouldn't allow it because it had placed a 3 hour lock on that feature due to my computer sending high volumes of email (possibly infected). I ran Norton quick scan, full scan and Norton Power Eraser scan. No threats were found. Before restoring my computer to my last full backup (prior to the problem showing up), I was looking to see if there were other options?
