Dropped VirusTotal recommendation, MetaDefender recommended instead

We no longer recommend VirusTotal for developers to scan new releases to check for antivirus engine alerts and end users to double-check possible false positives in their installed antivirus engine. This decision is due to poor availability of VirusTotal's engine (it was basically inaccessible for the last 3 days), slow performance of scans likely due to overloading of their servers, and poor quality of the scan results due to inclusion of low-quality antivirus engines and poor settings or beta definitions of some other engines. The end result of all of this is that, when we can get VirusTotal to work, you'll see a false positive from Bkav, Qihoo-360, and McAfee-GW-Edition on nearly every portable app you scan. Bkav and Qihoo-360 are low-quality engines that don't appear to respond to false positive reports. Qihoo-360 is reportedly spyware, anyway, like other software under the Qihoo umbrella. McAfee-GW-Edition appears to be an oddball variant of McAfee used as a web gateway scanner which is known to be exceedingly unreliable when it comes to false positives.

We now recommend MetaDefender for double-check scans before posting releases and for use by end users to check alerts from their local antivirus for false positives. MetaDefender is fast, includes all major antivirus engines (42 in all), doesn't include low and beta quality results that VirusTotal does, and has an easy to read UI.

I've updated our False Positive support section to recommend MetaDefender alongside Jotti and to remove links to VirusTotal: https://portableapps.com/support#false_positive
