Windows 7: Appdata folder keeps getting infected.

Alright guys I haven,t used my pc in a while and when i started it up after a month or so of being dormant I received the fbi greendot moneypack virus, it was stored in my appdata folder. I have been getting viruses in this folder ever since then. I use Opera, if that has anything to do with it. I use Avira and malwarebytes as an antivirus. I have never had issues with viruses before on any platform because I don't do stupid stuff, but this is a first. Any help on how to stop this nonsense?
