Disable autorun if you suspect a virus on flash discCan inserting a flash disc that might contain a virus into my CPU and viewing that file or photo without moving or saving or sending that harmful file to my C drive cause that virus to infect my C drive? In other words, can viewing a file on an I drive cause any potential virus to infect a C drive?Some flash drives will autorun when inserted. This could be a problem, so disable autorun by holding the shift key down while you insert the flash disc. The type of viruses that can be embedded into graphic files take advantage of making certain programs run malicious code through something called a buffer overrun. Internet Explorer has been susceptible to buffer overrun attacks, though recent security updates for Windows XP and Internet Explorer have addressed many of these issues. You should always have your PC up to date on all security updates, but in a case where you suspect that a graphic file may contain a virus, I would not use Internet Explorer to view it. Use something a little more benign, such as MSPaint. Before doing anything with the suspected files, scan them using your antivirus program. And if I had reason to think a file contained a virus, I wouldn't attempt to view it or keep it on my system.
