I came across this website by chance:
I took a look and noticed some apps from fdroid repo are marked to have viruses, in some cases even 20 virustotal engines find a trojan virus.
The application that I use from time to time and that is APK Extractor, and I was really surprised that it is marked with 7 virustotal engine as a virus trojan.
Here we come to the question
Are all applications on the f-droid safe to use?
Does the app pass any security and safety tests before appearing on the F-droid?
While some think any open source application is secure, it can normally be malicious.
