connected to pc and selected disk drive. Went through folders on phone and moved pics to PC external drive and moved a few from external drive to phone. After I finished I selected charge only and disconnected. Then check phone for pictures and ones transfered were there, went back to phone and some of pics transfered are gone, pics not associated with phone gone, videos gone from other cameras, missing documents in folders on PC and external hard drive. No security warning from Kasperskys when I connected phone to PC, just a pop up concerning new pictures found in which I just hit cancel. Now I'm running Kasperskys and found thus far 2 JAVA Trojan viruses.
Some of the videos file names looke encrypted with symbols.
