Regarding "Computer Booster v2"

Alright, I've downloaded the thing when it was still approved. After waking up the next day, I see a message saying I downloaded a keylogger from one of the mods/owners of the website.

So, my question is. I've ran three scans, an AVG one, a McAfee one and a Spybot S&D one, according to those, my computer is clean now, is it safe to log into anything right now? And if not, how do I completely remove this douchebag's keylogger?

Thanks in advance.

i run the avg 2 times and used also malwarebytes on my noob pc that i downloaded that crap and now it shows that its clean.. so hope its good now when usede avg 2 times and malwarebytes 2 times

Refrain from using Bad Language, Flammatory Posts. He Really doesnt need to buy anything if all Three Scans are Stating that they are Clean. Might be Safe, Just to be Sure Do a Full System Scan
