    Five months ago computer infected by detectle and undetectable malware (botnet etc.).
    I formated and installed Win 7 again, but before that I took backup using my usb flash disk.

    Now I think that the flash disk is infected, because after this I heard that some malware infects the flash disk and spreads.

    So now I am worried to plug it into my "new" computer... I do not want to get reinfected.

    I do not know what to do, where to start, how to protect myself and against which threats...

    OS: Win 7 64-bit.
    What can I do?

    Really grateful for help, because I don't think anyone want trojans, botnets or keyloggers on their PC.

    Not Really Sure :/
    try Looking at the content From a Non Computer Device

    Like A Dvd Player or Playstation or something that don't use Windows as system

    Look For unusual Folders + .ini .bat .exe Files

    if there is something like this try to move them to Folder better be compressed
    then upload them to Virustotal Or Jotti

    Is it possible to insert the USB flash drive into something else other than a computer device to go through the content?

    Thanks for your suggestions btw. I will do that :)

    Just boot from a Linux Live CD. Connect the usb drive, then upload files to VirusTotal.

    Very good idea about the linux live cd.

    Is there any risk to my windows setup if I use that, or any risk for using linux?

    The Linux definitely won't be affected, because CDs are read-only and RAM is volatile.
    Windows shouldn't be affected because it's inactive. If you want to make sure, dismount it, and then mount usb drive.
