How did I get infected with?

The Polarity Yahoo Search hijacker did not hack your computer. It is not that advance. The parasite “hacked” you. It tricked you into installing it. That is right. Your actions got you in this trouble. Were you a bit more cautious, you wouldn’t have to deal with this infection. This hijacker has very limited installation rights. It cannot access your system without your approval. No permission, no admission. That’s the rule. Make sure you don’t give this permission unintentionally. Do your due diligence. Use the Advanced/Custom installation option. Only under the Advanced option will you be able to see whether extra apps are about to be installed. Many software developers attach additional programs to the payload files of their applications. These third-party apps, more often than not, are parasites like the Polarity Yahoo hijacker. Don’t give these unknown apps access to your system. Deselect them. Make sure you know what you are giving your permission to. Read the terms and conditions (of course, you can use an online EULA analyzer to sped up the process). If you detect anything out of the ordinary, abort the installation immediately. Other parasite distribution methods you should keep an eye out for are the good old spam emails, torrents, and fake updates. Only your caution can keep your device virus-free!

In theory, you will get ads for sports shoes if you enter “sneakers” into a search engine. Yes, it definitely sounds great. But in reality, all these “great deals” should be avoided. They are all unreliable. They arise unwarranted expectations, at best. Yet, they are more likely to redirect you to scam websites. Numerous criminals use the hijacker to reach potential victims. They want to either lure you into subscribing to unneeded services, downloading rogue software, or disclosing financial details. With the hijacker on board, you are more likely to end up on a phishing website than on a legitimate one. Bear this in mind the next time you see an irresistible online offer. If a deal looks too good to be true, it probably isn’t.
