Certain changes are made in the browser such as a replacement of the default address used as homepage and of the browser’s search engine tool that gets used whenever the user tries to search for something on the Internet. For instance, if your search engine used to be Google, after the hijacker’s installation it has probably been replaced by some unknown to you search engine tool that doesn’t provide the same level of quality in its searching services. Oftentimes the browser hijackers also get the user page-redirected to questionable and misleading sites – gambling sites, browser game sites, or different online stores. Chrome, Firefox, Safari, and pretty much any other browser could get infected by a browser hijacker.

In some cases, some such programs are even known to show ads right over the main part of an online page, covering that part and forcing the user to click on the displayed ads just so that it would go away and reveal the actual contents of the page. Furthermore, some of the ads may be misleading and may try to scare you into downloading fake anti-malware programs by telling you there’s a virus in your system.

If some site or an online pop-up tells you your computer has been compromised just ignore it without touching it.
