What is REOptimizer?
The REOptimizer application is developed by AltoCloudMedia and offers metadata analysis and fraud control features. It claims to be a digital marketing-oriented app. Although it may seem useful, REOptimizer is classed as potentially unwanted application (PUA), as is distributed using the "bundling" method and is often installed unintentionally.
As with most applications of this type, REOptimizer is free to download and might provide minor 'free' features, but more advanced features require users to purchase the paid 'full' version. The app then displays supposedly useful stats or other data. In many cases, these are simply attempts to trick users into purchasing bogus products.
Furthermore, the products often do not provide the features promised, tools, etc. It is possible that REOptimizer is one of these rogue apps, since it usually is installed inadvertently due to the "bundling" method. Furthermore, other adware-type or browser-hijacking apps might also have been installed as part of the 'bundle'.
Most of these additional apps deliver intrusive ads, collect information, and cause unwanted redirects. Therefore, we advise you to uninstall REOptimizer and check for other unknown/unwanted programs or applications installed on your computer and browser.

The internet is full of potentially unwanted applications with different functionality. Example of these apps include SweepTools PC Cleaner, Cosmos System Care, and Swift PC Optimizer. There are often installed unintentionally and provide no real value. Furthermore, some PUAs generate revenue by collecting data, delivering ads, etc.
How did potentially unwanted applications install on my computer?
Although REOptimizer is available for download on its official website, most PUAs are installed when software developers employ the "bundling" method - stealth installation of potentially unwanted applications with other third party software. Developers hide these apps in "Custom", "Advanced" and other similar options of the installation processes.
Therefore, information regarding bundled apps is not properly disclosed and they can easily go unnoticed (especially if the installation process is hurried, without carefully checking settings).
How to avoid installation of potentially unwanted applications?
Pay attention when browsing the internet and installing or downloading software. Avoid downloading software from unofficial websites/sources, using third party software downloaders, and installers. Check all available "Custom", "Advanced" and other settings/options of the installation processes and opt-out of unwanted software/offers.
Only then finish the installation. Bear in mind that most ads appear legitimate, however, some (especially intrusive ads) redirect users to unwanted/untrustworthy websites (gambling, pornography, adult dating, etc.). If you encounter these ads and redirects, check your browsers for unwanted/unknown extensions, add-ons, and plug-ins (depending on the browser).
If you find any suspicious entries installed on your browser or computer, uninstall them immediately. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
