How to remove theirsvendor[.]com from Mac?

What is theirsvendor[.]com?

Most people who open theirsvendor[.]com arrive at the URL address accidentally. It is used in various rogue advertising campaigns. For example, this address might be presented as a legitimate search result by various search engines. Once the result is clicked, however, it will open theirsvendor[.]com in a pop-up window, which then redirects users to a dubious website. Do not trust web pages that are used in dubious ad campaigns or on websites that are opened through them.

Research shows that theirsvendor[.]com is used to promote deceptive web pages that trick people into downloading potentially unwanted apps (PUAs). I.e., these web pages display fake virus alerts and encourage visitors to remove 'detected viruses' with dubious security applications. Do not trust these scam sites or use applications that are advertised on them. Another problem with theirsvendor[.]com is that it leads to various surveys (and possibly, other ads). These surveys might be used to obtain personal details that other parties could misuse to generate revenue. Furthermore, theirsvendor[.]com opens web pages that ask visitors for permission to show notifications. Generally, dubious pages display irrelevant notifications, advertisements, and so on. If clicked, they often cause redirects to other, potentially malicious websites. To avoid privacy/browsing safety problems, unwanted downloads/installations and redirects, avoid clicking links relating to theirsvendor[.]com and do not trust other sites opened through it.

Unwanted web pages are often opened through PUAs already installed on the system. Generally, people download and install apps of this type unintentionally. When installed, they open dubious site (cause unwanted redirects), feed users with ads, and gather data. If there are any PUAs installed on your browser or computer, remove them immediately.

How did potentially unwanted applications install on my computer?

Some PUAs can be downloaded intentionally, from their 'official' websites, however, people usually download/install them when they click deceptive ads or through set-ups of other software. In many cases, developers use a deceptive marketing method called "bundling" to include unwanted apps into the set-ups of other software. I.e., they hide PUAs in the options of various download/installation set-ups. For example, in "Custom", "Advanced" and other similar settings. If people do not check these settings, they can allow PUAs to be dowloaded and installed with other, regular software.

How to avoid installation of potentially unwanted applications?

Download software from official and trustworthy websites/sources. Avoid using torrent clients, eMule and other Peer-to-Peer networks, third party software downloaders, and so on. Check all "Custom", "Advanced" and other similar settings/options of software set-ups. Deselect offers to download or install additional software and only then finish the setup. If clicked, intrusive ads, usually redirect people to dubious web pages, especially if the ads are displayed on sites relating to pornography, adult dating, gambling, and so on. If unwanted redirects happen regularly or intrusive ads appear on any opened web page, check for unwanted extensions, add-ons, and plug-ins installed on the browser and remove them. The same applies to unwanted programs 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.
