I emailed the email address in that post, its been months with no reply. I was actively posting on WO at the time, and even the person who reported the malware post had the remark that I was most likely hacked. I have no reason to waste years of reputation over a few bucks I'd get from spreading malware
Yep, it's pretty much the standard scammers practice, to hack accounts and then use them for posting creating fake announcement threads with malware.
Report Malware and Suspicious Links here so Mods can take Action thread is full of similar cases, and I personally tagged quite a few of those. In majority of cases they hack low level account, but every once in a while higher ranking accounts is used.
Looking at your posting history, it really looks like your account has been hacked, as posting a known malware link in the part of the forum where that you usually don't visit (mining) really looks odd. I do remember that some members complained after getting their accounts banned due same reason as yours and they got ban lifted so hopefully there is still a chance for you to get your account back.
