    Just wondering if this is anything to be concerned about.

    I have noticed a new 0.1g FAT32 partition. It has just recently showed up and this after my AV program blocked/removed a virus.

    I do not see it from Windows 7 Manage drives but it shows up on my backup program, Acronis TrueImage. Like i said it is a new addition so have no idea why it is there.

    would a USB flash drive do this? i also -about a month ago- got an ADATA AS102-32G-RGY Pro 32GB USB3.0 - only looked deeper at the settings in TrueImage recently so cant say for sure when this fat32 partition appeared.

    just makes me suspicious because of the virus block and that the partition does not show up in the windows manage>drives app.

    Sounds like the standard Win7 boot partition. I don't remember exactly, but i think it's a FAT32 100 MB partition. It's supposed to be there.

    this FAT32 is recent. i already had the 100mb system reserved partitions that win7 put on.
    i can not see this drive in anything but my backup program (Acronis True Image)
    In the win7 disk management it shows the physical drives (120g SSD and 2T Seagate)
    plus the 100mb system reserved partitions (and they are HPFS not FAT32) but the .01mb FAT32 is not there

    Virus/spyware etc scans show me clean. (Microsoft Security Essentials) MSE was what blocked the Trojan. Just started using BitDefender to see if there is something that MSE missed. but all looks good.

    so the only other thing is the new Adata flash drive(got about a month ago), it has "OStoGO tool assists you by converting your Microsoft Windows 7 Installation DVD to an ADATA portable storage device"

    i guess i will dig deeper re:adata. I havent looked deep on the backup program for a while. So i cant say for sure when this FAT partition appeared. It was not there when i set up the back ups 2 months ago. It does daily (mon-Fri) backups on one drive(WD element) and a weekly on a 1T seagate in a "BlackX" enclosure.

    Did you also scan with malwarebytes and an online virus scanner like one by ESET?
