MajorSearchLetter Mac Redirect Activity Report
Just like other unwanted programs for Mac, such as InetSearch, NetSearchAgent and Searchnt, MajorSearchLetter may also end up on your Mac without you knowing. This is typically done with the aid of software bundling – the act of including apps, like MajorSearchLetter to the installers of other freeware downloaded from the web. This is often done by adding this app in one of the install steps of the downloaded program in question, often located in the “Custom” rather than the “Express” installation mode, making it difficult to detect.
Once MajorSearchLetter is added to your Mac, it may change certain settings of your web browsers. These include changing the home, new tab, default search and other default preferences to display its own site, instead of the original ones you are used to.
This is mainly done so that MajorSearchLetter could start to slow your Mac down with the following annoying advertisements:
- Third-party website transfers.
- New banners that replace legitimate ones on the sites you visit.
- Push notifications.
- Pop-up promotion.
- Search result advertisements.
- Ads linked on the text of the sites you read from.
But this is not all. The software may employ trackers, like pixels, geo-locators, cookies, LSOs, tags, and others. MajorSearchLetter may use those trackers to obtain the following information from your online browsing activities:
- Your browsers’ history.
- What you search.
- Your last pages seen.
- Bookmarked sites.
- Your location and language.
- Your mouse clicks, scrolls and movements.
But when compared to the risks of the ads this software may display on your computer, the trackers are the least of your worries. Since most of these ads are shown by third-party services purely for profit, they may sometimes lead to third-party websites that are risky, such as:
- Software download sites that are fraud.
- Redirects to other adware and risky domains.
- Scam pages.
- Virus websites that infect your device with malware.
- Fake tech support.
- Survey scams that are phishing.
- Fake websites designed to steal information.
This is why it is essential to take immediate steps towards removing MajorSearchLetter from your Mac as soon as possible.
