I've never trusted Windows Defender - it sees viruses in the simplest files - it lies all the time.Windows Defender is just as good as any other anti virus softwareLaugh all you want. There been a few files on here like Dokan Marketplace that then hacks the Wordpress installation once installed and start injecting files into the installation. Can't blame me for being careful
Dozens of antiviruses are collected on the VirusTotal website.
Don't you trust them?
Maybe your computer itself is infected with viruses, like your Defender?
The case, of course, is yours - you can continue to trust your defender.
I also checked the Addon for viruses: revslider-fluiddynamics-addon. Everything is fine. I am attaching the archive.
