On this page, I intend to maintain a list of the best free tools for Windows. Each entry will be appropriately marked as being either totally free, unlimited trial, adware or nagware.
To the best my knowledge none of these is any kind of malware.
AVG Anti-Virus
AVG Free Edition is the well-known anti-virus protection tool. AVG Free is available free-of-charge to home users for the life of the product! Rapid virus database updates are available for the lifetime of the product.
TextPad
TextPad is a powerful, general purpose editor for plain text files. Easy to use, with all the features a power user requires.
SpaceMonger
SpaceMonger is a tool for keeping track of the free space on your computer. Each file or folder on a given drive is displayed in a box in the main window whose size is a relative comparison to all the other files in your system.
Firefox
A better, safer web-browser. Enough said.
Thunderbird
Thunderbird makes emailing safer, faster, and easier than ever before with the industry’s best implementations of features such as intelligent spam filters, built-in RSS reader, quick search, and much more.
DeskPins
DeskPins can be used to make any application topmost, that is, to keep it above all other windows. Just grab a pin from the DeskPins icon in the system notification area (a.k.a. taskbar tray) and click on any window. This functionality is identical to the “Always on Top” setting found in some programs. With DeskPins you can add this feature to any program!
