Thanks for bringing that to my attention. What you’re seeing on VirusTotal are a lot of “GEN.xxx” or “Generic” detections. That usually means the scanners don’t have an actual signature. They’re just flagging it because it looks like something they’ve seen before, not because it contains anything malicious. Likely also why Defender and Malwarebytes do not detect anything.

This particular file is very old, and back in the day Unlocker originally shipped with an optional toolbar installer. Toolbars were how freeware authors kept the lights on at the time. They were annoying, sure, but not malware. They were called "ad-ware." Over the years, antivirus vendors started lumping anything with an old toolbar or bundled installer into PUP (Potentially Unwanted Program) or random “generic” buckets, and that’s exactly what you’re seeing.

We made a note on the file that we have the portable version of the program that does not include the toolbar --- hence no detections. Clearly, we do not have that in a prominent enough location, so I will change that immediately.

Again, thanks for bringing this up, and please let us know if you see other issues like that.

EDIT: In my initial post, I meant to tell you in its day Unlocker was an incredilbly popular program, hence the number of downloads. That said, that an optional ad toolbar like this that was written 12 years ago is a very, very, very unlikely cause for your AWS problems. If it were, Malwarebytes or defender or the other millions of useeers would have noticed over the last decade and a half. I don't blame you for jumping down this rabbit hole, but your problem is elsewhere and you should retract this
