Remove FastAgain PC Booster (Uninstall Guide)
FastAgain PC Booster is a system optimizer utility, which is promoted via other free downloads, and once installed it claims that several issues were been detected on your computer.
However, if you try to fix these issues, FastAgain PC Booster will state that you need to buy its full version before being able to do so.

FastAgain PC Booster is a paid system optimizer program that is typically added when you install another free software (video recording/streaming, download-managers or PDF creators) that had bundled into their installation this program. Very often users have no idea where did it come from, so it’s not surprising at all that most of them assume that FastAgain PC Booster is a virus. This program is also bundled within the custom installer on many reputable download sites, so if you have downloaded a software from these websites, chances are that FastAgain PC Booster was installed during the software setup process.
FastAgain PC Booster it’s technically not a virus, but it does exhibit plenty of malicious traits, such as rootkit capabilities to hook deep into the operating system, browser hijacking, and in general just interfering with the user experience. The industry generally refers to it as a “PUP,” or potentially unwanted program.
Some examples of the interface, fake alerts, fake scanning results, and pop-ups displayed by FastAgain PC Booster are shown below:


The Windows registry is a database that Windows and its applications store their settings in. It contains hundreds of thousands of entries. Some of the entries may be slightly outdated — maybe you’ve uninstalled a program and it left a key or two behind, or maybe a there’s a file extension with no associated application.
FastAgain PC Booster scan your registry for these outdated entries and offer to remove them. Because there are so many registry entries to go through, this program may sometimes also remove useful registry entries, causing you problems. The Web is full of stories from people who have run a registry cleaner and encountered problems. In a best case scenario, FastAgain PC Booster will remove a few hundred unnecessary entries and reduce the size of your registry by a few kilobytes. This makes no different in perceptible performance.
If you must use a registry cleaner, you don’t have to pay anything. Using a free registry cleaner, such as the registry cleaner included with the respected CCleaner utility, is good enough.
You should always pay attention when installing software because often, a software installer includes optional installs, such as this FastAgain PC Booster. Be very careful what you agree to install.
Always opt for the custom installation and deselect anything that is not familiar, especially optional software that you never wanted to download and install in the first place. It goes without saying that you should not install software that you don’t trust.
