Is Disk Defrag Free a trustworthy program?

Disk Defrag Free virus – this is how some computer users start calling this system optimizer, which we categorize as a potentially unwanted program (PUP)[1]. There is no reason to call Disk Defrag Free a virus because it is not malicious[2]. However, some of its features can greatly annoy you, and you shouldn’t tolerate them. It appears that Disk Defrag Free installer suggests installing two additional Auslogics (the developer) programs – Driver Updater and BoostSpeed 9. What is more, the Disk Defrag installer will recommend you to “Set Yahoo as your homepage and default search engine.” If you agree to do so, Yahoo Toolbar will change these browser settings in Chrome, IE, and Firefox. Although Yahoo search is not malicious – it is entirely legitimate, you might not want to change your current homepage and default search engine. However, if you tend to quickly switch through software installation by clicking “Next” repeatedly, you probably won’t even notice these suggestions.

Disk Defrag Free is categorized as system tool because it is not a dangerous program, however, it hardly adds any useful features to computer. It has an aim to advertise other programs, so do not be surprised if it sends you ads with suggestions to install additional programs every once in a while. The developer admits that in its Privacy Policy: “Auslogics Products may provide links to third-party websites and products.” However, the developer also says that it has no control over third-party websites or their products. This gives us an idea that it doesn’t care whether these sites are safe or not, so we suggest you not to trust or install third-party products advertised by this disk defrag tool or related programs. If you want to remove Disk Defrag Free from your PC, employ Reimage or similar software for its removal. You can find manual Disk Defrag Free removal guide right below the description of this potentially unwanted program.

How could I install this program?

You can download Disk Defrag Free from its developers’ websites, however, we do not exclude the possibility of installing it alongside another free program[3]. We discovered that this program itself is a software bundle[4] that contains two additional programs, so we assume that it can also be distributed by other programs, too. To avoid installing it without an intention to do it, we suggest selecting Custom/Advanced settings in software installers[5]. Remember that software bundling is a widely used technique to distribute potentially unwanted programs, and surprisingly, it is a legitimate trick. If you choose our recommended settings, you will get a chance to see the extras included in your download and opt them out.
