So I downloaded this .exe file as I kept getting a message for it and being suspicious I run it in the avast sandbox. It started a setup which I allowed to run and see what Avast does. Suddenly avast gave the virus message and the computer became nonresponsive for a few seconds until I did CTRL+ALT+DEL and then it went back to usual desktop. The malicious program looked like a adobe setup and said setup completed, which I know is fake. However, it also generated an error message saying it is not getting required previleges from administrator before the compuer screen became blank for a few seconds.
Later I deleted the .exe. I ran virus scan and all was clean. I also tried to find why I was getting this request and it seems it has to do with bittorrent which I have removed from my machine.
Do I need to format the computer? Has my security and data protection been compromised? What do I do next?
