Normally I don't discourage the use of programs which are designed to help, especially when they're malware free, but this is an exception. I must agree with Cnet's download.com Editor's Review, which was generous in giving this utility 2/5 stars. The only things going for this program are its small size (70KB) and the fact it runs on Windows 98 through 2003.
The highlights:
* There is no user interface.
* Launching the program presents a small dialog box, which stays on top of all other windows and cannot be minimized.
* You cannot change the scan settings, period.
* You are not told what is being scanned, or what is being removed, only its percent completion. (I've heard several complaints about it deleting required program files without even notifying the user!)
* The scan is extremely slow. (It took nearly an hour to scan one of my ''testers,'' which has an 80GB hard drive.)
* Once the scan starts, it cannot be canceled.
* It only found a few things missed by my other scans, which took about a minute each.
Given this program's limited usefulness and potential for causing serious problems with your computer, I recommend staying away from Dustbuster XP.
