I've just been infected with the above. Bitdefender Total Security didn't prevent it and didb't detect it it when I did a quick scan. Isn't this the sort of thing Bitdefender is suppose to protect against? I've found an article which involves using Malwarebytes to remove the offending software so I will use this. Disappointed that I have to use something other than Bitdefender, though. Have I misunderstood what Bitdefender can do?
