If you care like a little tiny bit or are unresponsible when browsing the internet :kekw:
As follows:

Free, sorted by gut feeling:

ESET Online Scanner
Microsoft Safety Scanner
Kaspersky Virus Removal Tool
Panda Cloud Cleaner
Trellix Stinger
Zemana Anti-Malware
Comodo Cleaning Essentials
AdLice RogueKiller

Other
Gridinsoft Trojan Killer (for that specific niche of malware)

Paid:
Gridinsoft Anti Malware

Shouldn't use, why:
Norton Power Eraser: Getting discontinued
Malwarebytes: Runs in the background eating up RAM, aggressive advertising of premium version

Some of these also support Windows XP, see here

Almost all of these are free on-demand scanners, (for the exception of the single Paid one) which means you get a free-forever tool that just scans and removes malware by your request. Full protection is available from all the companies that provide these, if you were to need it.
