I have a virus called important.exe which is apparantly a bitcoin miner and is chewing up my CPU. It keeps automatically launching even after ending the process in task manager. The file comes up in C:\Users\"name"\AppData\Local\Temp\nhq so when I delete it, it's recreated and I can't find what keeps creating the program. I've gone through my Programs and Features and no suspicious programs are there. After doing a full system virus scan through Avast it's shown up as completely clean. I know that this virus can be picked up after scanning my system with SpyHunter4 although I have to register to actually remove the virus which I have no intention of doing. Essentially, I'm looking for a reliable antivirus/malware program that is free and able to pick up this virus.
