Why my computer acts sluggish, and why do I see so many DNSMystic ads on my screen on a daily basis?

DNSMystic virus is a dangerous computer infection that causes annoying advertisements[1] appear on a computer screen on a daily basis. Other known as DNSMystic adware, this program is believed to belong to the DNSUnlocker group[2] of potentially unwanted programs (PUP). As is known, DNSUnlocker adware is an ad-supported program that maliciously pushes third-party advertisements to the user and making a virtual layer on the screen. The program tries to deliver sponsored content via banners, in-text links, pop-up and pop-under ads, interstitial ads, and other forms of advertising. It appears that DNSMystic functions in the same way. Although DNSUnlocker malware is advertised as a tool that helps to “access Geo restricted web sites” by changing DNS settings[3], and, judging by the name of it, DNSMystic is probably going to be praised the same way, it is better to avoid these programs as much as possible. DNS Mystic might configure browser shortcuts, install helpers and change your browser settings to gain full control of your web browser and use it for its own purposes. It seems that now this adware program can affect all major browsers, including IE, Firefox, Chrome, Safari, and most likely others. If infected, these browsers will start displaying DNSMystic ads at random times.

Annoyance is not the only problem that “Ads by DNSMystic” cause. Most importantly, these advertisements are not trustworthy, and consequently it is not safe to click on them. Each of them carries a link pointing to an external third-party website, and not all of them are secure to visit. Besides, content displayed by these ads might not be real, too. Do not be surprised if a click on an interesting-looking ad throws you on a completely suspicious gambling or gaming website. Sadly, just like any other adware-type program, DNSMystic might collect information about your browsing activities and habits, analyze it and use it to provide you with a selection of targeted third-party advertisements. We must point out that the aim of ad-supported programs is to convince users visit external websites and generate pay-per-click[4] revenue this way. However, we already mentioned that these websites might not be safe, for example, they can advertise vague software pieces, for instance, adware or browser hijackers. In the worst case, you might come across a website that falsely claims that a certain program on your computer is outdated and you need to install updates. Remember – such updates can be bundled with spyware or malware, and you definitely do not want such software on your computer. If you suspect that your system is infected with this threat, better remove DNSMystic immediately. The most efficient DNSMystic removal method requires an anti-malware or anti-spyware program, and if you do not have it, we suggest installing Reimage software.

How did this adware manage to slip through Firewall and infect my PC?

The most shocking fact about adware programs is that the majority of them are considered to be legitimate programs. DNSMystic adware is one of them. However, techniques that it uses to infiltrate the target system are not so fair, at least in our opinion. The software spreads with a help of other free programs and can be easily installed alongside many free programs available to download online. Therefore, you should set proper installation settings when installing programs downloaded from the Internet. Contrary to a popular belief, “Default” and “Standard” installation settings are not the best choices. They often hide statements about additional third-party software added to the main program. Your task is to switch the installation settings to “Custom” or “Advanced” option and remove ticks from agreements to install these extra programs.

How can I fix my computer after DNSMystic hijack?

In order to fix the damage that DNSMystic adware has done, you have to uninstall this ad-supported software from the system. The best way to remove DNSMystic virus is to scan the entire system with anti-malware[5] software to detect all files that belong to it. In case you are willing to test your DNSMystic removal skills without using anti-malware software, you might want to rely on instructions written by our experts:

You can remove DNSMystic automatically with a help of one of these programs: Reimage, Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus, Malwarebytes Anti Malware. We recommend these applications because they can easily delete potentially unwanted programs and viruses with all their files and registry entries that are related to them.
