I'm not as savvy as I once was but we had this happen years ago......
It installed a keylogger and soaked up a couple of credit card numbers. We keep a close eye on such matters and noticed a couple of strange charges pop up later. I ran a scan and sure enough, it caught two malicious programs.
Back then I think it was Ccleaner and Malwarebytes......Malwarebytes caught it. Norton was a big waste of time as it slipped right past that.
Watch your accounts.
We get reports of this constantly at work. Big waste of time as most of the ones we see are off shore and we have enough trouble getting investigators to handle local cases.
