So I bought a thumb drive from target (Lexar) and loaded a bunch of photos from my Mac to the drive. No other files, just photos and little movies from iphoto that were mad on my digital cam or iphone. She plugged the drive in and her computer blanked out and nothing would run. It changed her "verizon" browser logo to ADV and a pop up came up telling her to install a virus scanner. My aunt went over there to help her and ran virus scan and found 9 "viruses". She scanned the drive but nothing came up. She told me though that all the negative activity showed on the virus scan to have started on the date the drive was inserted and that she had to stop all activity after that to access the cpu. She said that all the photos on the drive duplicated themselves and there were a ton of hidden files starting with *_Doc. Again, the virus scan detected nothing on the drive but there were hidden files there. Could I have transfered something via the thumb drive? One of my friends says it is unlikely but possible and another thinks it was a trojan activated by her putting in the drive. The only things that I guess would be necessary info is that the Thumbdrive was brand new, and that I used a digital camera that I sometimes plug into my work pc. Also there was a pic or two that was placed on the thumb drive but removed that I copied the image from the internet. Any ideas? I don't want anything bad on my CPU that can hurt other computers.
