The program can be downloaded from its official site located at onepcoptimizer.com. The website contains a lot of information about the optimizer and creates an impression that it is a reliable tool.

Do not believe in any problems the application claims to have found on your system. OnePCOptimizer tries everything to persuade you that you need to purchase the tool for $19.99. You are promised a 30-day money-back guarantee, but no one could be sure if the promise would be kept.

Our security specialists have found that OnePCOptimizer can come packaged in bundles with untrustworthy applications.
