AllPCOptimizer is the newest clone of such infamous potentially unwanted programs as WinPCOptimizer and OnePCOptimizer. This infection enters without permission when users execute malicious installers set up by cyber criminals, which is a sign that this program cannot be trusted. Even if the interface of this program suggests that it is trustworthy, no reliable program can enter without your agreement. Unfortunately, once installed, it can feed you false information that might push you into registering for a licensed version of a program that deserves immediate removal. Whether or not you have invested in it, you have to remove AllPCOptimizer right away.

If you do not, you might miss your chance to remove malicious software before any damage is done. Even if AllPCOptimizer is the only malicious program on your PC – which is highly unlikely – your hands are full. This fictitious system optimizer is completely bogus, and t is important to delete it ASAP.

The creator of this infection needs to convince you that your Windows security is in trouble, so that you would be willing to pay $19.99.

Moreover, if you register for the full version of AllPCOptimizer, you will not receive the security you need.
