It is a common practice for the cost-free applications to encourage you to install some suggested additional programs. The developers of freeware do it for a commission, but this tactic may hide risks to the end user in case the promoted software is not legitimate. This is the case with Zeast PC Tuneup that is a Potentially Unwanted Program (PUP). You shouldn't give your permission to its installation because this tool may cause many issues later on. The people responsible for the creation of Zeast PC Tuneup advertise it as a reliable system optimizer. Allegedly, it should boost the speed of your PC by deleting the useless 'junk' files. According to their words, the PUP also should fix various errors, including broken registry entries. One of the promised features of Zeast PC Tuneup that may mislead some people to install it is that it offers protection from malicious programs. Unfortunately, Zeast PC Tuneup cannot provide the expected utility because it is not a real system optimizer. The company that stands behind it is unnamed. The product has no official site and relies solely on the bundling method for its installations. The consequences if you load Zeast PC Tuneup may be rather unpleasant. The PUP may interfere with the functionality of other applications, including your browsers. It will not be surprising if your web clients get filled with unrequested and annoying pop-ups, banners and automatically started videos. Zeast PC Tuneup also may lock essential processes of your Operating System (OS). If it happens, the questionable application may suggest you call a number like 800-935-0823 for assistance. However, this way you will not connect with qualified technicians but with con artists who may try to take your money. To protect yourself, you need to use special security software to delete this PUP right away.
