How to remove GuideRecord from Mac?

What is GuideRecord?

GuideRecord serves advertisements, modifies browser's settings and possibly collects browsing data and/or other data. Therefore, this app functions as adware and a browser hijacker. Most of the times users download and install apps like GuideRecord unknowingly, therefore, they are called potentially unwanted applications (Mac). It is known that GuideRecord is distributed by disguising its installer as the installer for Adobe Flash Player.

GuideRecord adware

Some examples of types of ads that applications like GuideRecord serve are various banners, coupons, surveys, pop-up ads. It is worthwhile to mention that their ads tend to be designed to promote (open) dubious sites, in some cases they are designed to start download or even installation of some PUA by executing certain scripts. As mentioned in the first paragraph, GuideRecord functions not only as adware-type app but also as a browser hijacker - it modifies browser's settings such as the address of a default search engine, homepage and new tab. It changes those addresses to an address of some fake search engine. Typically, fake search engines provide results generated by some other (usually legitimate) search engine, however, sometimes they can be designed to generate their own results that may include links to potentially malicious sites. Typically, changes that where made by a browser hijacker can be undone only after its uninstallation (address of a fake search engine can be removed from browser's settings only when a browser hijacker is no longer installed on a browser and/or the operating system. Additionally, it is likely that GuideRecord collects details related to user's browsing activities. For example, IP addresses, geolocations, entered search queries, addresses of visited websites or even more personal, sensitive details. In such case its developers could sell recorded data to third parties (potentially cyber criminals), or they could misuse it to generate revenue in other ways. Users of apps that function as data collectors can become victims of identity theft, experience problems related to browsing safety, online privacy, and/or encounter other issues.

CleanParameter and TrustedAnalog are the names of apps that are similar to GuideRecord. Usually ad-supported apps generate revenue for developers by generating advertisements. However, it is common that they promote fake search engines and/or gather various data as well. To summarize, apps like GuideRecord are useless to their users and should never be downloaded and installed.

How did GuideRecord install on my computer?

GuideRecord is distributed via deceptive installer that is designed to look like the installer for Adobe Flash Player. It is common that such installers are used to distribute not only PUAs but also malicious software like Trojans, ransomware. Also, it is common that adware-type apps, browser hijackers and other types of PUAs are distributed via download and/or installation setups of other programs. In such cases PUAs are included in the aforementioned setups as additional offers. As a rule, users can decline offers to download and/or install PUAs by unticking certain checkboxes or via "Advanced", "Manual", "Custom", or other settings. However, not all users change the aforementioned settings (or untick checkboxes) before completing downloads and/or installations. Therefore, they download and/or install not only wanted programs but also PUAs that are included in their download and/or installation setups. This distribution method for PUAs is known as "bundling". Also, in some cases PUAs are distributed via ads by designing those ads to execute certain scripts. However, those ads can cause such downloads and/or installations only if users click them.

How to avoid installation of potentially unwanted applications?

Programs and files should not be downloaded from unofficial pages, via torrent clients, eMule (or other Peer-to-Peer network), third party downloaders, etc., or installed via third party installers. It is advised to download files and software from official websites and via direct download links. Download and installation setups that contain settings like "Custom", "Advanced", or some checkboxes tend to include offers to download and/or install additional, unwanted apps. Those offers should be declined be declined before completing download and/or installation processes. Also, it is recommended not to trust ads on shady pages. Quite often they are designed to promote questionable websites, or even to cause unwanted downloads, installations. All unwanted extensions, plug-ins or add-ons that are already installed on a browser and programs of this kind that are installed on the operating system should be removed. If your computer is already infected with GuideRecord, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
