Let's face it, one of the primary jobs a Windows admin does is keep machines free of infection. It's inevitable - end users will open files, install cutesy apps, and go to sites they shouldn't. When they do these things, their machines get infected. When their machines get infected, you could wind up fighting a losing battle - unless you have the right tools.
Sometimes the antivirus tools installed on the machine just aren't enough. When that time comes, you'll be glad you have one (or more) tools on your USB drive to help you out. I've found five such tools that could certainly get you out of a serious pinch. All of these tools are portable and work like champs.
1. ClamWin Portable
ClamWin Portable is very much like its big brother: It's free, open source, and does a great job of disinfecting machines. ClamWin has a very high detection rate, has frequently updated definitions, and has an easy to use graphical interface.
