How to remove Chrono SpeedUp

Chrono SpeedUp is a rogue-type program distributed across many Windows users. The main concept of this utility lies in PC optimization to keep your system clean and protected against malicious threats. Unfortunately, many experts, as well as users themselves, tend to express heavy doubts about its capabilities. Chrono SpeedUp is suspected of fabricating scan results to force users into activating the license. In other words, this is a premium version that has to be purchased to access all features of the optimization program. Without it, users will be unable to delete all threats outlined in fake post-scan results. Chrono SpeedUp is not the first program we see of this sort. According to some sources it is one of the hundreds of clones of notorious PC Accelerate Pro scam. There have been many similar programs like Chrono SpeedUp pursuing money, but not quality. Nobody downloads them intentionally, so their creators use unwanted and stealth distribution methods to get installed against users' consent and make them believe their PC needs help. If you really want to equip yourself with modern and high-quality optimization software, it is better to opt for already trusted and long-existent programs like IObit Uninstaller, IObit, and other reputable products. We encourage you to delete Chrono SpeedUp from your system as long as it brings no value to the PC experience. Make sure to follow our instructions below and get rid of the program completely without traces.
