The Prestoris.com website is bad news. If it begins to take over your screen, you’re in trouble. Your system is no longer infection-free. An adware application lurks somewhere in the corners. And, it’s that adware, which forces the site on you. Think of the page as a front. The infection uses it as a shield to hide behind, and wreak havoc. And, it does wreak a lot of havoc. Adware tools don’t waste time. Their mess-making programming kicks in as soon as they sneak in. Its presence first becomes apparent with your browsing. You suffer redirects and pop-up bombardments every time you go online. And, the incessant intrusions cause further frustrations. Your computer’s performance slows down to a crawl. Your system crashes more often. Understand that with an adware on your PC, problems pop up all the time. And, they don’t stop. They’ll just pile up until your system can’t take it anymore. And, what do you suppose happens then? The Blue Screen of Death takes over. Yes, the odds of that happening are pretty minuscule, close to non-existent. But, they do exist. So, as insignificant as the chance may be, are you prepared to take it? Are you willing to gamble with your system’s well-being? And, for such a worthless, hazardous program? Not to mention, the adware behind Prestoris.com, threatens your privacy, as well. So, to allow the adware to stay is ludicrous. You’d place your private life, as well as your PC’s well-being, on the line. And, for what? Nothing but headaches and troubles. Avoid that. Do yourself a favor, and delete the program ASAP. Once you see Prestoris.com show up, act. Find and delete the adware, hiding behind it.

How did I get infected with?

How do you imagine you ended up harboring adware? We bet you have no memory of installing the tool? Even though, truth is, you did. Oh, yes. YOU agreed to install the tool. You may not remember it, but you did. Adware applications have to gain permission to enter. They have to ask whether you consent to their installment, and only get in after you permit it. So, if you’re dealing with adware, it’s because you allowed it. But don’t be too hard on yourself. At the time, you didn’t know you were doing it. Confused? Let’s explain. The infection does seek your permission on its install. However, it doesn’t do it openly. If it just popped out in the open to seek access, you’d deny it. So, instead, it turned to trickery. It used the old but gold means of infiltration to fool you. Freeware, fake updates, corrupted links, spam email attachments. These are the most common methods, which adware tools use for their deceit. But there’s one key ingredient without which neither one can succeed. And, that’s your carelessness. So, don’t be careless! Be cautious when installing a tool or an update. That way, you can avoid installing an infection on accident. Always make sure to read the terms and conditions! Do your due diligence instead of agreeing with everything, and relying on chance. Chance and luck are NOT your friends. Vigilance and caution are.

Why is this dangerous?

If you’re careless enough to allow adware into your PC, brace yourself. Issues start to roll shortly after its install. It all begins with your browsing. It turns into an utter hellish experience. Every time you open your browser, a new tab, or do anything online, you suffer disruptions. Adware applications are quite meddling. So is the one, you’re stuck with. It forces the Prestoris.com site on you constantly. You even find the page in place of your default homepage and search engine. But all the problems mentioned so far are minor. They’re the minor grievances you face due to adware. There are much bigger ones. But the one that towers over them all is the security risk. The nasty adware, hiding behind Prestoris.com, spies on you. It begins immediately after invasion. The program keeps track of your online activities. And, it doesn’t stop at there. It does more than monitor you. It also catalogs every move you make. Then, after it decides it has gathered enough data, it sends it. That’s right. It hands it off to the unknown third parties that published it. That means strangers with agendas get a hold of your private information. Are you okay with that? Are you going to allow these people access to your personal and financial details? Or, are you going to protect it from their clutches? Not to mention, you’ll protect your system from their hazardous influences, as well. Do yourself a favor, and don’t allow the adware to stay even a second after detection. As soon as you discover its existence on your PC, act! Locate its exact hiding place, and delete it! The sooner the infection is gone, the better. Prestoris.com is a warning. Don’t ignore it.
