VAF Compressor is not the right application to use when you want to compress your files. Although it doesn't display harmful codes, it may still cause you inconvenience. This stand-alone program may interfere with the web browsers of the clients and causes unwanted changes, which is why the experts classify it as a Potentially Unwanted Program (PUP). Its official site vafcompressor.com isn't the only place you can use to download it. The people behind VAF Compressor, who have introduced themselves as "The Company", may rely on the bundling tactic to spread their unreliable tool. It means that some freeware that you download intentionally may encourage you to install VAF Compressor in addition to it. Some PC users may agree to do so because this program promises to increase the file compression/decompression speed by 40%. Allegedly, this application should work equally well with 16 different types of file extensions. However, the announced features are there for only one reason, which is to encourage the user to install VAF Compressor. After that moment, the PUP starts working in a way more negative manner than expected. It may generate many pop-ups, banners, interstitial ads, videos and animations that you may see when you launch any of the installed web clients. The modifications in Google Chrome, Mozilla Firefox and Internet Explorer don't end here as VAF Compressor also may change the default homepage automatically. The PUP also may create a toolbar that may be of no help to you. The new marketing materials may disrupt the normal functionality of your web clients. If you click on them, some ads may take you to sites that are potentially dangerous. The experts advise you to delete VAF Compressor with a powerful security suite and to search for an alternative program.
