I put my flash drive into an infected computer (a WHOLE ton of viruses, don't ask, silly me...) and put it back on my computer (seemingly clean, Avira and Spybot scan). When i double click on the removable disk from my computer, it says "Cannot find Setup.pif" or something of that like, happens on every clean computer now, though I've never left my flash drive on a clean computer for very long. The worst part is that now my computer doesn't give me the error anymore while all other computers do. I ran a full scan on the flash drive using Avira and I ran a whole system scan with spybot, all clean they says. I accidentally confirmed the virus: on a clean computer, I pluged it in and a virus alert came up and told me my flash drive was infected. I was in a hurry so I didn't catch what antivirus it was. My flash drive doens't exhibit any strange behavior and I don't see any suspicious files and I wouldn't mind reformatting the drive too much, but I would prefer not to because I would have to move all the files to my computer, format, then put them back on, maybe even put the virus back. My computer seems normal too. I just found an "autorun.inf" file on my flash drive said to autorun "setup.pif". I guess that means the clean computers do not have the virus and get the error, but my computer does! I deleted that line of code, which was also the only line. Thanks!
