What is Sinergia Cleaner?

Sinergia Cleaner is a fake antivirus program, which reports non-existent security infections. This is in the hope that unsuspecting PC users fall for the trickery displayed and purchase a so-called 'full version' in order to remove the supposedly-detected security threats.

In fact no security infections indicated by this rogue program actually exist on the computer - Sinergia Cleaner is a scam created by cyber criminals. This program is proliferated via 'exploit kits', which infiltrate users' computers through any security vulnerabilities detected within outdated software.

This program does not appear to be well thought out or professional - probably a beta variant created for testing purposes. Wide distribution of Sinergia Cleaner is unlikely since cyber criminals display many spelling mistakes within the fake security warning pop-ups.

Furthermore, the user interface is primitive and there is an overall impression that the creators of this scam did not spend much time developing it. Nevertheless, this bogus program has exhibits typical fake antivirus features such as blocking execution of .exe files, hijacking Internet browsers, blocking the Task Manager, etc.

This is identical behavior to other widely-distributed fake antivirus programs such as Antivirus Security Pro, System Care Antivirus, and many others.

Note that buying this program is equivalent to sending your money to cyber criminals, and moreover, you will divulge your banking information - potentially leading to further thefts from your credit card account.

If you have already paid for the license key of this bogus software, contact your credit card company and dispute the charges, explaining that you have been tricked into buying a fake antivirus program. To eliminate this fake antivirus program from your system, use the removal guide provided.
