I just upped some files to VT(older ones that already have been uploaded which I rescanned and some completely new ones.) Prevx is still right there among the scan results.
Prevx is still there I know as I upload downloaded malware files and sometimes Prevx dosn't show up but for what reason I don't know but it is there most times! TH
I think it just depends on the time, sometime the recently added SAS does not show up and sometimes other AV's don't show up no idea why it happens though.
