Firefox trojan false positive (?)

wallmenis@lemmy.one to Firefox@lemmy.ml – 15 points –

Hello all.

I recently downloaded firefox from the official site as per usual (windows version) and I ran a virustotal check and got a trojan positive.

The md5sum is: 4409905bd4544c6f45e4d5737f130d75

The sha256sum is:

d390bfce3fed1be8c153aebfb9f28043981071b5338745e9207547178f32bf64

Please verify if this file is legitamate.

It's signed by Mozilla (extremely unlikely that's a virus unless they got hacked) and it's detected as trojan only by "max secure", a questionable snake oil product that is like a broken clock, correct only twice a day

Conclusion: it's safe

I've been using computers for 30 years and never once has an antivirus program been helpful or accurate. But yeah, I don't download and click on random stuff from the web.

False-positive?

I have read on the firefox forum that this particular anti-malware engine flags these like that. I just want to know to be sure. Is there somewhere where I can check if it was officially generated by firefox (other than the signature which seems legit)

Follow up:

Ok so aparently 7z compression is the culprit. If I extract the file. There is a setup-stub.exe file that shows clear in there.

Maybe try installing trough a package manager like Winget or Chocolatey
