Hey,
If Avast has detected the malware using its real-time scan mode it has almost certainly stopped the malware before it could do anything.
As it is clearly a type of malware that Avast knows about the fact that your complete system scan revealed nothing proves that it is no longer on your computer.
You have nothing to worry about.
I notice that you originally linked to the infected file on this forum, may I ask you not to do this in future please? Other people may accidentally click it, and it is generally not good for a forum to contain links to any malware.
If it puts your mind at rest, it's a good practice to make a note of the exact virus\malware that your Anti-Virus detects and look up what it is. The vast majority of threats they detect are browser hijackers and invasive advertising tools which, while unpleasant, aren't a major cause for concern to your computing (and can usually be removed - though they can be a major pain sometimes).
Have a good day, and enjoy your computer fear free
