computer a ) this is infected with any and every infection you care to imagine, it still boots up and technically works and the files haven't been encrypted but for the sake of argument it's got every virus that exists.
computer b ) this is an old machine, somethign like xp, which hasn't been online for months, and won't ever go online again. Technically you might say it had an antivirus, but given xp is an old unsupported and vulnerable OS, and givn that the antivirus has not had a definitons update for many many months it might as well have no antivirus.
Now a user wants to copy files from computer A to computer B, in such a way that there is no risk of the virus being spread to computer B, the files are wide range of things (including some which are opened by programs which have vulnerabilities in them) but none of them are .exe files. Computer B can NEVER go online, even just to open a gmail account and download files from there. Computer A, is as we've said infected but still capable of normal operation. It will happily write files to usb or cd, but who knows if it's writing virus files alongside them at the same time. Use of a third or fourth machine is not allowed. How can the user transfer the files
(.jpg, .avi, .png, .gif, .tga, .skp, .skb, .blend, .blend1, .blend2, .obj, .dae, .tga, .xcf, .doc, .docx, .7z, .zip, .mpg, .wmv, .txt, .ppt, .pptx, .pdf, .pub, .rtf, .html, .rar, )
between the machines without ricking the virus going along for the ride, either hidden within a file or on the transfer medium?
Why do i ask this: as far as i know neither of my computers is infected, but my xp machine is old, hasn't gone online since before the end-of-suport date and doesn't have up-to-date definitons for it's antivirus, nor does it have programs updated, some of those programs have been found to have vulnerabilities since the end of support date. The (windows 8)machine with the files on should be clean but given the circumstances it is better to treat it as infected so that on the very small chance that it is then copying the files over won't give the infection to the old machine. It might be a little paranoid to think like this but for these pruposes treating the new machine as if it were infected is the best way to ensure security throughout the copying process. What is the most risk-free way of copying files acrosss under the circumstances i have described. It's also kind of useful to know this incase anything ever goes really wrong in future.
