Frequently Asked Questions (FAQ)

What is the purpose of a fake anti-virus?

Fake anti-viruses, like other types of unwanted applications, are designed to generate revenue for their developers. Typically, fake security software claims to detect various threats on users' devices and requests activation (purchase) to remove them.

It is noteworthy that unwanted apps can also profit by running intrusive advertisement campaigns, causing redirects, or collecting private data.

Unwanted apps, such as fake anti-viruses, are usually considered legal because their End User License Agreements (EULA) provide information about their potential behavior.

Is having Galileo System Cleaner installed on my computer dangerous?

Users risk experiencing financial loss by purchasing this nonfunctional piece of software. Furthermore, unwanted apps like Galileo System Cleaner often have harmful abilities and/or their installation setups are bundled (packed together) with dangerous apps. Hence, other potential risks may include system infections, severe privacy issues, and identity theft.

Will Combo Cleaner help me remove Galileo System Cleaner fake anti-virus?
