How does ContentStyles adware spread? What issues does it cause on a MacOS?

ContentStyles is a program that is classified as an adware. Hence, it is not a computer virus as its main purpose is not to damage your system and files. However, it still poses certain danger to the security of the infected operating system.

ContentStyles is a potentially unwanted program that acts like a typical adware. It affects Mac operating systems by tricking users into running its configuration files. You may have installed this adware by following steps presented on a bogus website, downloading and installing freeware with a corrupted installer or simply visiting a website that triggers an installation process on the background of the browser.

Once it finds a way to gain access to a macOS it alters main browser settings without asking for permission. Then it starts delivering various intrusive advertisements like pop-ups, pop-unders, banners, in-text links, and so on. The ads may appear on almost every website you visit. However, be careful with these ads. They are not placed by the official websites’ publishers. Actually, the publishers do not know that these annoying ads appear on their websites. Hence, there is no guarantee whether these ads are associated with trustworthy offers hosted on secure websites or they load fake promotions hosted on poorly secured/dangerous websites.

Since the purpose of these ads is to lure you into visiting sponsored content, the adware is designed to collect various personal and non-personal information. So once ContentStyles tricks you into running its activation files on your Mac, it creates additional files, activates tracking technologies and starts spying on your online activities.

Even though this adware is not a malicious program, it can trick you into visiting hacked web pages. As a result, you may become a victim of a drive-by attack and then malware infection.We recommend the immediate removal of ContentStyles adware from your affected Mac and browser.
