Take antivirus with you where ever you go with ClamWin Portable - this is a free stand-alone virus scanner that the security conscious can take with them on a USB key and use to scan files before they run them. The page I've listed for Portable7zip is in French but rest assured, the utility itself is in English. If you have Portable7zip installed (a portable version of the free 7zip compression tool) then you can handle a multitude of compressed file formats. Unfortunately you don't have anything to decompress the file on the PC you are using. You've been sent a compressed file by email and want to see what's inside it.

It can also be used to create good, random passwords.

PasswordSafe is a simple yet secure password storage utility that can be used to organize all your user names and passwords. Without a doubt, the best password storage utility that I've come across is called PasswordSafe. Everything I need to access my data and even send and receive email is stored on the USB drive. On top of that, DmailerSync Plus also allows me to create a copy of my Internet Explorer and Firefox favorites and also any files that I select and take these with me too. However, I have found a great software utility called DmailerSync Plus which allows me to clone my Outlook data (emails, contacts, tasks and so on) and access them from the USB drive. My main email client is Microsoft Outlook, so there's no chance of installing that onto a USB flash drive and making it portable. OK, so you have your flash drive, what applications can you load onto it? There are plenty to choose from! I like this drive because everything I load onto it is password protected and encrypted using 128-bit hardware-based AES encryption. My current flash drive of choice is a 2GB Kingston Data Traveler Elite Privacy Edition. This allows you to have plenty of storage space for applications while leaving you with enough space for files and backups. You can probably get away with using a 512MB drive but I think that 1GB is better, while 2GB is ideal. The more capacity you have the better, really. The first thing that you need is a USB flash drive that has decent capacity.
