How to Uninstall PCguardian Registry Cleaner?

Issue: Installed PCguardian Registry Cleaner somehow. I didn’t do that intentionally, so not its “free” scanner is really pissing me off. If I want to uninstall it using an in-built uninstaller, I get a prompt to purchase a licensed version or if the prompt does not show, the removal fails. How to remove it?

Solved Answer

Just like Magic PC Cleaner, MyPCProtector, RegistryFix, or Pcobserver, PCguardian Registry Cleaner is a rogue optimization utility, which has been developed by doubtful third-parties to prompt people purchase the licensed/full version of a useless optimization tool. Although it’s not malicious, security experts classify it as a potentially unwanted program (PUP) and recommend people to be more careful when installing freewares.

PCguardian Registry Cleaner is not distributed directly. It is disseminated as an attachment of free programs like download managers, PDF creators, games, and so on. For example, if a PC’s owner opts for installing a free utility and selects Quick or Basic installation option, the full installation setup, which normally should notify about PCguardian Registry Cleaner attachment, will not be shown. Consequently, the rogue cleaner and other attachments will be installed by default.
