No, I didn't check with the AV sites you mentioned - one part of the problem is that if I leave my AV to do his thing it cleans the downloaded archives and they can't be opened (7-zip complaint). I disabled the AV only to get them down, 7-zip was ok with them, used last beta, and so I got it! But I powered off the system in the middle of something (there were already some weird things going on) and on power on it became evident that there is a problem, even the simplest thing, like double clicking "My Documents" or "My Computer", didn't work as expected, due probably to registry inconsistencies - did I tell you I powered off the system in the middle of something? I could have submitted the archives to AV sites, but another part of the problem is that this kind of sites can be used for malware optimization too - bad guys just submit themselves their "work" until they get "AV clearance", so to speak.
