I can see the emails being sent out by outlook on my computer (computer accessing smtp and sending them when outlook is open... sending 1 of 1823). I cleaned the PST, created a new PST and copied my inbox into it. I did a malwarebytes scan, antirootkit scan, adw, found nothing at all.

 

I was receiving tons of chinese spam, blacklisted the domains from China, but I'm at a loss at how to make the stupid outlook stop sending spam by itself. How does it do it?

 

Edit: closed outlook, renamed pst, opened outlook, created new empty pst, it's still trying to send 1800 emails....

 

Edit2: Ok so I went to the webmail, there was still 1000+ mails there in chinese, deleted those, blocked 126.com/163.com/qq.com in the admin panel, then on the computer, I flushed the Outlook Files and recreated the PST.... in the admin panel, it shows 0 sent for today... which is good....

 

Why am I (seemingly) not detecting any infection if I (was) sending spam? I confirmed that the IP from which the emails were sent was the office's IP... and there's only two computers here and only one with this account... and I physically SAW outlook trying to send loads of emails... I also reset the password...
