What is PC Gold Optimizer and system repair?

PC Gold Optimizer and system repair is advertised as a tool which allows users to boost PC performance, block unwanted URLs and files and delivers a real-time antivirus protection. However, the distribution method of this software is questionable. For this reason PC Gold Optimizer and system repair is categorized as potentially unwanted application (PUA).

PC Gold Optimizer and system repair unwanted application

PC Gold Optimizer and system repair includes tools such as malware cleaner, registry cleaner, startup optimizer, disk defragmenter, privacy cleaner, junk cleaner and some other tools. It allows users to scan the operating system for malware and various issues. However, detected issues, threats cannot fixed or removed without having to register (purchase) PC Gold Optimizer and system repair. It is worthwhile to mention that PUAs of this type can be designed to trick users into paying for their activation/registration by providing fake scan results. It is unknown whether PC Gold Optimizer and system repair is one of these programs, however, such a possibility exists. Another issue with PUAs is that they often are distributed together with other potentially unwanted apps. For example, various adware-type apps, browser hijackers. Adware types are PUAs that serve advertisements, and browser hijackers are the apps that are designed to promote fake search engines by changing certain browser settings. Moreover, such apps can be designed to collect various information, including sensitive, personal details. It is not recommended to trust programs like PC Gold Optimizer and system repair or have other PUAs installed on a browser and/or computer.

To sum up, most of the times programs like PC Gold Optimizer and system repair are advertised as tools that supposed to clean computers, fix errors, remove malware and/or be useful in some other ways/have some other features. However, not all of the programs that are categorized as PUAs function as they supposed to. Therefore, it is advised to trust only truly legitimate programs. More examples of PUAs are ID SafeXpress, Registry Cleaner, CleanMyPC.

How did potentially unwanted applications install on my computer?

Sometimes users download and/or install potentially unwanted apps by clicking unreliable, deceptive ads that are designed to execute certain scripts. Although, more often they cause it when software developers distribute PUAs by using a deceptive marketing method called "bundling" To be more precise, when various unwanted apps are included in download and/or installation setups of other programs as additional offers. In most cases such offers can be declined in "Custom", "Advanced" and other settings of setups. Although, not all users do that when they download and/or install programs that have those apps included in their setups. By leaving the aforementioned settings unchanged users allow for included PUAs to be downloaded and/or installed alongside with the desired software.

How to avoid installation of potentially unwanted applications?

It is recommended to download software from official, trustworthy websites and not to use third party downloaders Peer-to-Peer networks (like torrent clients, eMule), unofficial websites and other similar tools, sources. Third party installers should not be used too. Furthermore, setups that have "Advanced", "Custom" and other settings should be always checked for offers to download and/or install unwanted software. Such offers should be declined before finishing downloads and/or installations. Intrusive ads that are displayed on shady pages can open potentially malicious websites, or cause unwanted downloads, installations. For this reason those ads should not be trusted/clicked. Any unwanted apps (extensions, add-ons or plug-ins) that are installed on a browser should be removed. Software of this kind that is installed on the operating system should be removed too. If your computer is already infected with PUAs, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
