Think I'm Infected

Hi, I’ve just run an exe that apparently is a virus posing as dhl tracking information. The program didn’t appear to do anything, am i infected ? My email is virus scanned twice, once by my hosted service and then by NIS, I did ask NIS to check the file before I ran it and it came back ok. I have put the file into quarantine now and submitted it! Full system scan from NIS & Malwarebytes show 0 threats, so am i safe ? Please advise!
