So, I accidentally executed an installer downloaded from the web, Avast didn't recognize it as a virus. Nonetheless, by seeing properties I saw it was a network monitoring app, it added a process in my computer "Oneetx.exe".
After searching online I found it was a virus. I localized it inside the Roaming Temp folder. It also configured itself to start on system startup.
I used both, SpyHunter and Malwarebytes to analyse my computer, only SpyHunter detected a threat, and it was the same program, "oneetx.exe" and all files detected where inside Temp folder also.
So I deleted the original downloaded files, forcefully killed the process, and then deleted all files that could be deleted in the Temp folder. Checked for any new programs installed with control panel (nothing there) and emptied the recycle bin. Restarted my computer and re-run SpyHunter, Malwarebytes and Avast, neither detected any threat. I also don't see any oneetx.exe process running. Now I'm going to uninstall Malwarebytes and Spyhunter.
Am I safe now?
