How to remove SkillFormat adware from the operating system
Written by Tomas Meskauskas on (updated)
What is SkillFormat?
SkillFormat generates advertisements and promotes a fake search engine address, and thus functions as adware and a browser hijacker. Additionally, it is possible that SkillFormat gathers information relating to users' browsing habits and other data. This app is distributed via a deceptive installer that is disguised as the installer for Adobe Flash Player.
Typically, users download and install apps such as SkillFormat inadvertently and, for this reason, they are classified as potentially unwanted applications (PUAs).
SkillFormat adware overview
In most cases, applications such as SkillFormat serve coupons, banners, surveys, pop-up ads and other ad types. When users click these ads, they open untrusted web pages or even cause download/installation of unwanted applications.
SkillFormat promotes a fake search engine and functions as a browser hijacker. A typical browser hijacker achieves this by changing the default search engine, homepage, and new tab to the address of its associated fake search engine. In most cases, these search engines do not generate unique, individual results, or they generate those that can include links to dubious pages.
Furthermore, it is possible that SkillFormat collects various data relating to users' browsing habits. For example, IP addresses, geolocations, entered search queries, and addresses of visited websites. It might also be capable of accessing personal, sensitive details. Developers of adware sell gathered information to third parties (potentially, cyber criminals) or misuse it to generate in other ways.
Users with these apps installed on their browsers and/or computers might become victims of identity theft, encounter problems relating to browsing safety and online privacy, and other issues. Therefore, SkillFormat and other such apps should never be trusted.

Adware examples
SkillFormat and similar apps simply generate revenue for the developers by serving advertisements, promoting specific addresses, and collecting data. Most are useless to regular users, even if they are advertised as useful, legitimate apps. Some examples of other apps similar to SkillFormat are SkilledObject, InitialSkill and CleanParameter.
How did SkillFormat install on my computer?
SkillFormat is distributed via a fake installer that is designed to appear like the installer for Adobe Flash Player. In some cases, these deceptive installers install malware (e.g., ransomware, Trojan-type malware).
Browser hijackers, adware-type apps, and other types of PUAs are commonly distributed by integrating them into the download and/or installation set-ups of other programs, so that a proportion of users inadvertently download and install them together with their chosen software. This distribution method is known as "bundling". Offers to download and install additionally-included apps usually appear in "Advanced", "Custom" and other settings of the set-ups (where they can usually be declined). Many users fail to check and change these settings, thereby granting permission for PUAs to be downloaded and installed by default.
In addition, unwanted downloads and installations are sometimes caused by clicking deceptive advertisements capable of executing certain scripts.
How to avoid installation of potentially unwanted applications?
Download software and files from official websites and via direct links. It is not safe to use torrent clients, eMule (or other Peer-to-Peer networks), third party downloaders, unofficial websites or other sources of this kind. Avoid third party installers. Check "Advanced", "Custom" and other settings, and decline offers to download or install unwanted software.
Do not click ads that are displayed on dubious websites, since they can open other untrusted websites or even cause unwanted downloads and installations.
Remove any unwanted, suspicious applications (extensions, add-ons, and plug-ins) that are installed on the browser. The same should be applied to programs of this kind that are installed on the operating system.
If your computer is already infected with SkillFormat, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
