DNS Changer – How Did I Get It and What Does It Do?
Similar to DNSUnlocker, a dangerous adware that attacks Windows PCs, DNS Changer also uses the same tactics. It may come in your Mac as a result of being bundled to a third-party app installer. In the installer, you can find it as an optional offer that helps you access geo-restricted sites and lets you see forbidden content outside of your country. However, it does way more worse things than that.
Once installed on your Mac, the adware may begin to target the hosts file on your Mac. It alters the default DNS address in this hosts file with it’s own one, allowing it to manipulate what you read on your web browser. The outcome of this is that many forms of ads may start to appear on your Mac, such as:
- Browser Redirects.
- Ad-supported search results.
- Push notifications ads.
- Highlighted text ads.
Not only this, but since this nasty virus has your control over your DNS connectivity, it may also snoop in on what you do online and this includes tracking the clicks you make, the sites you visit and even the passwords you type on them.
The main danger associated with this adware, however, is that it may cause redirects and lead you to dangerous sites, such as:
- Phishing pages.
- Virus-infested sites.
- Tech support scam pages.
- Fake survey scams.
