Is there a reliable and free (inexpensive) antivirus?

Question

Antivirus

There is a computer with Windows 8 in the pantry, on which various parsers, position checkers and other applications for Windows are spinning. Of course, you need to install an antivirus, which I did.
Delivered Nod32 - there was a constant problem with adding software to the list of exceptions.
The fact is that I use slightly specific software, which many antiviruses consider to be malicious. Of course I'm trying to add it to the exclusion list - Nod32 seems to not see it.
Demolished Nod32, installed Avast. He skips frank viruses. I knew for sure that there was a virus on the flash drive, I inserted it into the computer - Avast does not care.
Well, the question, in fact - which antivirus really works, normally processes the list of software with exceptions and is free (or inexpensive).
Separately, I will explain that a Windows computer is a remote server to which I connect via TeamViewer. So the computer is turned on around the clock, but I use it for a maximum of a couple of hours a day. I just think the choice of antivirus should affect the fact that the computer is turned on around the clock.
