How to remove theirsvendor[.]com from Mac?

What is theirsvendor[.]com?

Theirsvendor[.]com is a URL address that most people open accidentally. It is used in various rogue advertising campaigns. For example, this address might be presented as a legitimate search result by one or another search engine. However, once that result is clicked, it will open theirsvendor[.]com in a pop-up window which will redirect users to some questionable website. We do not recommend to trust pages that are being used in shady campaigns or sites that are opened through them.

Research shows that theirsvendor[.]com is used to promote deceptive pages that are designed to trick people into downloading potentially unwanted apps (PUAs). To be more precise, pages of this type display fake virus alerts and encourage visitors to remove detected viruses with some questionable security application. We recommend not to trust such scam pages or to use applications that are advertised on them. Another problem with theirsvendor[.]com is that it leads to various surveys (possibly, other ads too). These surveys might be used to extract personal details that other people could misuse to generate revenue. Furthermore, theirsvendor[.]com opens pages that ask their visitors for a permission to show notifications. As a rule, questionable pages display irrelevant notifications, various advertisements and so on. If clicked, they often cause redirects to other, potentially malicious websites. To avoid privacy, browsing safety problems, unwanted downloads (or installations) or undesired redirects, we recommend to avoid clicking links related to theirsvendor[.]com or to trust pages opened through it.

Quite often unwanted pages get opened through already installed PUAs. As a rule, people download and install apps of this type unintentionally. When installed, they open questionable pages (cause unwanted redirects), feed their users with ads or/and gather various data. If there are any apps of this type installed on a browser or computer, they should be removed as soon as possible.

How did potentially unwanted applications install on my computer?

Some PUAs can be downloaded intentionally, from their websites. However, most of the times people download/install unwanted apps when they click deceptive ads or through setups of other software. There are many cases where developers use a deceptive marketing method called "bundling". They use it to include unwanted apps into setups of other software. To be more precise, they hide unwanted apps in options of various download/installation setups. For example, in "Custom", "Advanced" and other similar settings. If people do not check them, they allow for PUAs to be dowloaded and installed together with some other 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, various third party software downloaders and so on. Do not leave "Custom", "Advanced" and other similar settings/options of software's setups unchecked. Deselect offers to download or install additional software and only then complete the setup. Furthermore, intrusive ads, if clicked, usually redirects people to questionable pages, especially if these ads are displayed on pages related to pornography, adult dating, gambling and so on. However, if unwanted redirects happen regularly or intrusive ads appear on any opened page, then see if there are no unwanted extensions, add-ons, plug-ins installed on the web browser and remove them. The same should be applied 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.
