Hello, today I was doing an offer for a game I play to make premium credits. The offer said that in order to make the credits I had to download and play a flash game. I'm usually wary about these sorts of things, but this time I just went ahead and downloaded it... and avast picked up some sort of malware from my temp files.
The strange thing is even though the temp was removed the game never installed and I got a mysterious file called rkverify.exe on my desktop and in my processes.
I googled it and lots of things came up saying it's malware. I ended the process and deleted the strange file off my desktop and from my recycle bin. I'm not sure if it's gone completely and I'm feeling kind of unsure.
What can I do to make sure it's all gone?
