Perfect Optimizer removal instructions
What is Perfect Optimizer?
Perfect Optimizer is advertised as a software that supposed to repair, clean and optimize the operating system. Although, this program is distributed in a questionable way, therefore, it is categorized as potentially unwanted application (PUA). Users often download and install such apps unknowingly, unintentionally.
Perfect Optimizer includes two main features: "Memory Optimizer" and "Startup Speedup". These features supposed to optimize computers (improve their performance). Although, to be able to use any of its features users have to purchase the full version (enter license key). The problem with most PUAs is that they do not function as they supposed to: they do not fix any real issues and generate fake scan results to trick users into paying money for their activation. It is very likely that Perfect Optimizer is one of these programs too. Therefore, it should not be trusted (purchased). It is worthwhile to mention that its downloader is designed to promote McAfee and Avast - legitimate programs. Although, quite often downloaders and/or installers of apps like Perfect Optimizer are used to distribute other potentially unwanted apps (e.g., adware, browser hijackers). Adware-type apps are designed to serve coupons, banners, surveys, pop-ups and other types of advertisements. Such ads often are designed to promote (open) untrustworthy websites or even run scrips designed to download and/or install unwanted programs. Browser hijackers are designed to promote fake search engines (their addresses) by changing some of the browser's settings. It is worthwhile to mention that both adware-type apps and browser hijackers can be and often are designed to gather various data as well. Quite often they collect browsing data (e.g., IP addresses, geolocations, entered search queries, addresses of visited websites, and so on). However, there are apps of this type that are capable of accessing sensitive information as well. The bigger problem with it is that gathered data could be sold to third parties (potentially cyber criminals) or misused to generate revenue in other ways. Therefore, if an app (or apps) of this type is already installed on browser and/or operating system, then it should be uninstalled right away. Also, it is not recommended to trust programs like Perfect Optimizer.

Perfect Optimizer is quite similar to Registry Life, RocketFixio and WinOptimizer. The main reasons why such programs should not be trusted is because they are distributed in questionable ways and often do not fix any errors, issues or are useful in other ways. A couple of popular methods to distribute such programs are described below.
How did potentially unwanted applications install on my computer?
Quite often various potentially unwanted applications are distributed by including them in download and/or installation setups of other programs as additional offers. This distribution method is known as "bundling". As a rule, information about additional downloads and/or installations can be found in "Custom", "Advanced" and other settings of setups. The same settings can be used to decline those offers. Although, not all users check (and change) them. When users download and/or install programs without changing the aforementioned setting, they allow for additionally included applications to be downloaded and/or installed too. Also, unwanted downloads and/or installation can be caused by clicking deceptive advertisements that are designed to execute certain scripts.
How to avoid installation of potentially unwanted applications?
It is not safe to download software, files from untrustworthy, unofficial pages, through torrent clients, eMule (and other Peer-to-Peer networks), third party downloaders, etc. Third party installers should not be used as tools to install any software as well. The safest way to downloaded files and programs is by using direct links and and official websites. Furthermore, it is not recommended to finish downloads and installations without checking setups for "Custom", "Advanced" or other similar settings. Those settings often mention offers to download and/or install unwanted apps. Additionally, it is recommended not to click intrusive ads as well. They often open untrustworthy/potentially malicious websites or even cause unwanted downloads, installations. In most cases such ads appear on shady websites. Although, in some cases they may appear on legitimate pages too. If there are any unwanted, suspicious extensions, add-ons and/or plug-ins installed on a browser, then they should be removed. The same should be done with programs of this kind that are installed on the operating system. If your computer is already infected with PUAs, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
