Win32:GenmaliciousA-UMO [Adw] Detected on my Computer

I recently ran a virus scan using the free version of avast, and it discovered the threat "Win32:GenmaliciousA-UMO [Adw]" in C:\Users:\(my user)\Appdata\Local\Microsoft\Windows\INetCache\IE\SH7IW974\Setup[1].exe|>$QUICKLAUNCH\OAS\oas.exe
I have no clue how or when I got the virus, but I believe it may have happened after I loaned my computer to my sister a few months back. There were multiple viruses webroot found, some of which were win32 related. To be clear, webroot expired and I deleted it to replace it with avast. I let avast "fix" the problem automatically, but that didn't do anything at all. I rescanned a day later and the virus had returned from the quarantine while the file avast had quarantined wound up in my temporary internet files somehow. I understand that OAS files are pretty critical, so I don't want to play around too much without some guidance. How could I go about tackling this virus?

Neither of those even detected it. Is oas.exe supposed to be in appdata in the first place? I would think the file is too critical to wind up there, but I don't know much about it.

Thats how avast detected it.
Scan the file in VirusTotal to use the detection name for a removal tool.

Going with how you posted that [Adw] in the title, I'm assuming it's an Adware.

AdwCleaner Download

Download Adwcleaner and scan.
