DEFRAG
***Quick, easy way to defrag your hard drive. When you are not using your computer, it is your screen saver, defragging your files and goes off when you start to use your computer, AND it remembers where it left off.
CNET editors' review : Join your hard drive fragments together into a tight bunch with this freeware. Auslogics Disk Defrag's interface couldn't be any cleaner or easier to use.
Choose a hard drive from an easy-to-read pull-down menu, and Disk Defrag instantly displays the drive's size, and used and free space. The program even displays a pie graph for visual learners. One click starts the defragmentation process. The program's defrag process screen displays another handy visual. A sector map makes it easy to see how much of the drive is fragmented, allocated, or free. As the program churns away, the defragged sectors are displayed in blue. We found the program fast, even on older XP systems. A handy HTML report is prepared after each defrag session. A summary displays the total files and folders defragged, while the detail section lists the defrag outcome for each file. Novices to system administrators will love this easy-to-use hard drive defrag program.

ZONE ALARM FREE FIREWALL
 ***Your router has a firewall in it, but it helps to have a software firewall on your computer as well. This is a free program, easy to install. You will have to ‘train’ it a little. It will pop up periodically asking if you want to allow a program to do something – just read the program name and if it isn’t something you are familiar with, then go online and do some research before allowing it. It may be a perfectly safe program, or it could be something you need to block.
CNET editors' review:  
The bottom line: ZoneAlarm Firewall Free 9.2 has gotten quieter and more effective, and should be considered an excellent tool for replacing the adequate default Windows firewall with a stronger option that includes better outbound protection, antiphishing guards, and ZoneAlarm's behavioral detection network.
