How did I get infected with?

Crusader turns to the usual antics to invade your system. The old but gold means of infiltration come in quite handy. But they only take the infection so far. Then, it needs YOU to take it the rest of the way. Confused? Let’s explain. The application uses proven methods to slither into your system. Corrupted links, freeware, supposed updates, spam email attachments. The list is extensive. Take freeware, for example. It’s among the top most used invasive means. And, there’s a reason for that. Users tend to throw caution to the wind during its install. They rush, and don’t bother doing their due diligence. Instead of reading the terms and conditions, they say YES, and move on. And, that’s a strategy that almost always gets you into cyber trouble. Infections prey on carelessness. Don’t grant it, and make it easy for them to sneak in undetected. Be thorough. Vigilance goes a long way.

Why is this dangerous?

The Crusader is an ad-supported tool. In other word, its existence relies on its ability to make money for the people behind it. If it fails to generate revenue, it falls into oblivion. So, the program does its best to create web traffic, and pay-per-click profits. It redirects you to various third-party sites. All of which are unreliable. It bombards you with pop-up advertisements. None of which you should trust enough to click on. And, everything you see got chosen for your eyes only. It’s not random. It got picked for you, and you alone. The adware doesn’t waste time throwing random ads your way, and hoping for the best. Instead, it makes sure to display ones, deemed ‘appropriate.’ he infection studies you to make the proper selection. As soon as it invades, it begins to spy on your browsing. It tries to learn what sparks your interests, what entices you, your likes, everything. Then, once it gets to know you better, the bombardment begins. Click nothing it shows you, no matter how appealing it seems! Each pop-up you press, by accident or choice, allows more malware into your system. Yes, the ads conceal various malicious threats. And, your click equals consent on their installment. So, the more ads you trust, or are careless enough to press, the more malware you end up with. Add the security threat to the mix, and you see why, Crusader does NOT belong on your PC. Remove it ASAP. It’s for the best.
