Ok so I was just messing around with the browser extensions today and found out that another browser extension from gameplay labs called gameplay labs plugin was installed(obviously it got installed with that media plugin) but before removing it from the GUI of the browser I searched everywhere on the user documents, appdata but couldnt find anything on it.. Dont know how it was still there and why MBAM didnt detect it.. It was installed on firefox as well. It was enabled by default, even if I disable it will get enabled the next time I run the browser. At first the option to remove it completely wasnt there.. but after restarting the computer and disconnecting from the internet, I was able to remove it from both these browsers..
I searched a bit about this plugin and it has given so many people a lot of trouble.. Just google "Gameplay labs plugin" and you'll see
Anyway if it really is a spyware and it steals passwords and stuff so many sensitive information of mine has been leaked
Avast still hasn't added detection though, I doubt if they will do it in the future..
