File Compressor Pro Unwanted Application (Mac)

Also Known As: File Compressor Pro potentially unwanted application
Type: Mac Virus
Damage level: Medium

What is File Compressor Pro?

File Compressor Pro developers promote this app as an online tool for zipping (compressing) files, however, one of its distribution methods is the "bundling" method. Developers use this to trick people into downloading and installing various potentially unwanted apps (PUAs). File Compressor Pro is also used to promote bunnybarny.com, a fake search engine.

This app supposedly allows users to compress files in a single click. This may seem an easy-to-use and useful tool, however, apps that are promoted using deceptive methods should not be trusted. They often deliver no real real value and are installed with browser hijackers, adware-type, and other unwanted apps.

In this particular case, File Compressor Pro's installer is used to promote a fake search engine (bunnybarny.com). Therefore, by installing File Compressor Pro, people might unintentionally allow changes to be made to browser settings - in this case, assigning bunnybarny.com as the default search engine, new tab URL, and homepage.

Typically, these changes cannot be undone unless a specific app (in this case, File Compressor Pro or another browser hijacker that is installed with it) is uninstalled. Browser hijackers change browser settings and often gather browsing related data. For example, IP addresses, geolocations, entered search queries, URLs of visited websites, and so on.

Developers share this data with other parties (potentially, cyber criminals) who misuse it to generate revenue. If PUAs are installed with adware-type apps, users will encounter unwanted ads (coupons, banners, surveys, pop-up ads, and so on). If clicked, these open untrustworthy or malicious websites.

Clicking them can also cause download and installation of other unwanted apps. To avoid these unwanted downloads/installations, privacy/browsing safety, and other issues, we recommend that you uninstall File Compressor Pro and avoid installing PUAs in the future.

Most PUAs are promoted as useful tools, however, few of these apps operate as promised. They are often promoted using deceptive methods and installed with other unwanted apps. They also promote dubious websites. Some examples of other similar unwanted apps include Qbit Mac Speedup, Advanced Password Manager, and Cleanup My Mac.

How did potentially unwanted applications install on my computer?

People usually download and install PUAs inadvertently through clicked intrusive ads or together with other software. As mentioned, to trick people into unwanted downloads/installations, developers use the "bundling" method.

They include PUAs in set-ups of other software and hide related information in "Custom", "Advanced" and other similar settings of the set-ups. In summary, people cause unwanted downloads/installations by clicking dubious (deceptive) ads or when they download or install regular software without checking the settings.

How to avoid installation of potentially unwanted applications?

Do not use unofficial pages, Peer-to-Peer networks such as torrent clients, eMule (and other similar programs), third party downloaders or installers to download or install software. All software should be downloaded from official websites and using direct download links. Furthermore, downloads and installations should be handled properly.

No software setup should be completed without checking included settings ("Custom", "Advanced" and so on) and dismissing offers to download/install additional (unwanted) applications. Furthermore, do not click ads displayed on dubious pages relating to gambling, adult dating, pornography, etc.

These often lead to other untrustworthy websites (or cause unwanted downloads/installations). If unwanted ads or redirects are a common problem, unwanted software might be installed on the browser or computer. We recommend that you check the list of installed browser apps (extensions, plug-ins, add-ons) and uninstall all unwanted, suspicious entries immediately.

This should also be done with programs of this type installed on the operating system. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
