Title: Help! "error_408.exe" downloaded by itself – virus?

So I was trying to download a file from a sketchy mirror site (I know, stupid move) and instead of my file, I suddenly got a popup saying "error 408.exe – download complete".
I didn't click anything – it just started downloading on its own. Now it's sitting in my Downloads folder.
File details:
I haven't run it. My gut says this is malware/spyware. Quick search online says "Error 408" is usually a "Request Timeout" HTTP error – not an executable.
Did I dodge a bullet by not opening it?
What do I do now – delete it? Scan with something (I only have Windows Defender)? error 408.exe download
Reply #1 – TechGuy_Ricky:
Do NOT run it. That’s 100% a scam/fake error executable. Delete immediately, run a full Defender scan + Malwarebytes Free. Also check your browser for unwanted extensions or download prompts. Likely drive-by download.
Reply #2 – net_safety_nerd:
Yeah, an HTTP status code (408) doesn't become an .exe in legitimate software. Likely a trojan downloader or ransomware lure. You did the right thing by asking before clicking.
Reply #3 – OP:
Thanks both – deleted and ran a scan. Found and removed "PUM.Optional.Downloader" in registry. Restarted, seems fine now. Won't go back to that site again!
