What is BestForMac?

BestForMac adware in detail

Advertisements generated by the BestForMac application are likely to be used to promote download websites for potentially malicious applications, pages designed to trick visitors into providing sensitive information, and other untrustworthy sites. Also, those ads may be designed to cause unwanted downloads or even installations.

Another reason not to have BestForMac installed is that this app is designed to promote a fake search engine (its address). It hijacks a browser by changing its settings, such as the address of a default search engine, homepage, and new tab. BestForMac changes those addresses to an address of a fake search engine.

Pretty often, fake search engines do not generate their own results - they show results generated by other search engines like Google, Yahoo. Nevertheless, many fake search engines are designed to generate results containing links to shady websites and display advertisements. Either way, it is strongly recommended not to use them.

Another important detail about BestForMac is that this app may be designed to track IP addresses, visited websites, entered search queries, geolocations or other information. Moreover, it may be designed to collect credit card details, usernames, passwords, telephone numbers and other personal information.

BestForMac in general

BestForMac is an untrustworthy application designed to generate revenue for its developers by displaying advertisements and promoting a fake search engine. It is worth mentioning that users rarely install apps like BestForMac on purpose. Therefore, BestForMac is called a potentially unwanted application (PUA). More adware examples are DataBoost and WebResultsTool.

How did BestForMac install on my computer?

It is known that to trick users into installing BestForMac, its developers have designed its installer to look like the installer for Adobe Flash Player. It is common for fake installers to be promoted on deceptive websites stating that installed software is out of date or in other deceptive ways. Another important detail about fake installers is that they can be malicious.

Another way to trick users into downloading or installing PUAs is to include them in downloaders or installers for other programs as additional offers. This distribution method is called bundling. Users agree to download or install PUAs when they download or install other programs without changing "Custom", "Manual", "Advanced" or other settings.

In some cases, PUAs are distributed through advertisements by designing them to run certain scripts. Users download or install potentially unwanted applications through ads by clicking them. It is worth mentioning that ads designed to cause downloads or installations appear on untrustworthy pages.

How to avoid installation of potentially unwanted applications?

It is recommended to download applications and files only from official, trustworthy pages and use direct download links. Files, programs downloaded or installed via third-party downloaders, installers, Peer-to-Peer networks (e.g., torrent clients, eMule), unofficial websites can be malicious.

Also, it is advisable not to finish downloads and installations without checking downloaders and installers for "Advanced", "Custom", "Manual" and other settings (or ticked checkboxes) and declining unwanted offers. Ads on shady pages should not be clicked as well.

It is common that the aforementioned ads are designed to open other sites of this kind or even install PUAs. Any unwanted extensions, add-ons, or plug-ins that are already installed on a browser should be removed. The same should be done with software of this kind that is on the list of programs installed on a computer. If your computer is already infected with BestForMac, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
