removal by Olivia Morelli - - | Type: Browser hijacker
12 brings you dubious search results full of ads redirect virus is a highly suspicious search engine that is advertised via browser hijackers[1] and other extension-injecting programs. These potentially unwanted programs (PUP) replace default start page and search provider value with hxxp://, causing the affected web browser load it automatically.

It seems that virus currently targets Mac OS only. However, Windows users shouldn’t relax – there are plenty of similar programs that are meant to compromise this operating system[2].

According to report[3], Rack-search delivers Yahoo search results modified by Aztec Media. This company has earned a “developer of potentially unwanted programs” name already. If you notice that the tab name says “Aztec Media Yahoo search results,” you shouldn’t try to interact with such search results at all.

It is highly likely that clicking them can trigger redirects to untrustworthy Internet domains such as gambling or adult-only sites.

On top of that, browsing through links delivered by a suspicious third-party company can point to scam surveys, phishing websites, and sites promoting spyware/malware. We do not say that Rack-search is itself malicious, but since it generates revenue from driving traffic to certain Internet sites, it is better to be careful.

We strongly suggest you to remove today and alter your browser’s settings according to your needs.

There are two typical ways to remove browser hijackers. You can try anti-spyware tools suggested by our team (Reimage or Malwarebytes Anti Malware) for automatic removal, or take matters into your hands and delete the hijacker manually. If you choose the latter option, consider using instructions we added at the end of this post.

Dubious browser hijackers infect computers through software packages

The Internet is full of fascinating content, and nowadays, the majority of software is free. However, it doesn’t mean that they do not monetize their services in some kind of way. In most cases, they promote different free programs and earn money using pay-per-install scheme.

If you do not want to be tricked into installing something you do not want, you should choose proper software installation settings. Many PC users make the fatal mistake by trusting “recommended” installation configuration (usually Default/Standard/Basic ones). Instead of leaving pre-selected settings on, switch the selection to Custom/Advanced one.

Once you’ve chosen the right software installation settings, make sure you deselect every extra program suggested to you. If the installer asks you to add browser tools, search apps, new tab pages and other dubious software, disagree. Then you can proceed with the installation.

Stop browser redirects by deleting virus

If your Mac was compromised by virus, you could remove it using instructions we provided below. You should check Mac’s Applications folder and see if the hijacker added any suspicious programs there. Move them to Trash and Empty it afterward.

In case you are trying to remove, but for some reason, you cannot complete this task alone, do not hesitate and use anti-spyware software. It will help you to find the hidden parts of the hijacker and eliminate them all at once. This will definitely make the removal easier.

You can remove 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.
