Yes.
The PC’s keyboard and mouse are the most likely to carry viruses or malware, but almost all input devices for computers can infect your computer in one way or another. Make sure you take precautions when handling devices other than your own. Don’t plug unknown USB drives into your system; Beware of talking on Skype, when obviously an incoming call is not from a known number; and don’t click links in suspicious emails—they could contain malware designed specifically for prodding at an unsuspecting person’s device! One final note: leave your webcams off if they’re not in use, because either someone may be using them to spy on you remotely.
