The Fast Free Converter is a video file converter that inexplicably markets itself through third party bundles that include distributions of popular software, such as Daemon Tools or Flash Player. While, as far as malware researchers have been able to conclude, the Fast Free Converter doesn't have any functions that would endanger your computer, software that uses these types of disingenuous installation methods usually should be considered undesirable for your computer. Like other Potentially Unwanted Programs, you should delete the Fast Free Converter with a good anti-malware product – particularly since the Fast Free Converter often is installed along with several other PUPs, as well.

When Free Isn't Always Good for Your Computer

The Fast Free Converter claims to offer file-converting features for both audio and video files, although malware experts only have confirmed the latter, so far. For reasons known only to its developers, the Fast Free Converter also makes the usual move of being installed in the format of a typical browser add-on despite lacking any Web-browsing features that would make such a format necessary. Other than some potentially fraudulent marketing claims, malware researchers haven't found any major problems with the Fast Free Converter, as long as you look at the program independently of its distribution methods.

Depressingly, the Fast Free Converter's primary model for distribution is even worse than its file-conversion functions and appears to rely on bundles with unrelated programs. Currently, the Fast Free Converter has been seen being distributed with unauthorized versions of Adobe's Flash Player and the Daemon Tools program. Although the Fast Free Converter does offer to allow you to opt out, these programs don't normally include the Fast Free Converter, and many careless updaters may install the Fast Free Converter by mistake when clicking through the process. Malware researchers also have seen the Fast Free Converter being installed along with other PUPs, currently including:

Converting Your Computer out of Putting Up with the Fast Free Converter

While the Fast Free Converter is not a likely source of direct harm to your computer, allowing PUPs to remain on your computer may harm the overall performance or cause an inadvertent degradation of your Web-browsing security. Programs that install themselves in suspicious circumstances and tend to try to prevent their removal – just like the Fast Free Converter – always should be deleted with appropriate anti-malware tools, and SpywareRemove.com malware researchers note that any minimally competent brand of anti-malware product should be able to delete the Fast Free Converter with zero problems.

More than anything else, the Fast Free Converter is an example of the problems that come with trusting downloads from unofficial sources. Updates for major programs (Adobe's Flash Player, JavaScript, etc.) often are exploited as vehicles for the distribution of both PUPs and high-level PC threats – albeit almost always by third parties. If you see an advertisement or other non-Adobe source asking you to update Flash, you should pause and consider whether or not this 'update' could include the Fast Free Converter and other browser add-ons with it.
