This page aims to help you remove Police Block Virus. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

A common problem that a huge number of users encounter every day is when their Chrome, Firefox or Internet Explorer browsers get “attacked” by some sketchy and unwanted program that enforces a new homepage, adds new toolbars and search engines and also causes the browser to redirect you to various websites without the user’s permission. Obviously, this can be extremely frustrating and unpleasant. Generally, software that displays any of the aforementioned invasive behavior are regarded as Browser Hijackers. Recently, a new addition to the Hijacker family has been reported to invade the users’ browsers and implement various changes like the ones we already mentioned. That is why we have compiled the following few paragraphs, in which our aim will be to acquaint you with how these programs work, how potentially problematic they can get and what you need to do in order to remove Police Block Virus and prevent any more Hijackers from getting installed onto your PC.

Aggressive promoting

Basically, Browser Hijackers are all about advertising something. It could be anything. The most common objects of advertisement are other software products, websites, online services, etc. The issue, however, is not so much what the purpose of Police Block Virus is but how it achieves its goals. As you have likely noticed already if you have the nagging software on your PC, the techniques that are used for advertising are rather aggressive and sometimes even lead to people thinking that the Hijacker is some kind of malicious virus. On top of that, most Hijackers have little to no use for the owner of the PC they have been installed on. Sure, Hijacker developers might promote their products as being helpful internet/browser tools or PC productivity enhancers, but for the most part, even if they do indeed come with some form of useful feature, it would hardly be able to compensate for the Hijacker’s intrusiveness and tendency to nag you.

Comparing it to viruses

As we said in the previous paragraph, it is not uncommon that people would refer to a Hijacker as malware or a virus. However, this term is not exactly accurate when describing programs such as Police Block Virus. After all, it is up to everyone’s point of view how to refer to Browser Hijackers, but we will still give you a general idea of why they are different from actual harmful malware such as Trojan horses and Ransomware.

  • They do not try to remain unnoticed – Unlike most computer viruses, Hijackers are actually actively trying to be as noticeable as possible. On the other hand, viruses are almost always made so as to be nearly undetectable.
  • Browser Hijackers are generally not malicious – Even though the advertising techniques used by this sort of programs can sometimes get out of hand, they aren’t exactly known for trying to mess up your PC’s system or files. The same cannot be said about Trojan horses or the malicious Ransomware virus type.
  • Many programs of the Browser Hijacker type are legal and legit – Truth being said, even some respected and well-known companies are known to have produced certain rather questionable pieces of software that had certain hijacker-like traits. In contrast, real PC viruses are certainly illegal and also employed for illegal purposes.

Do not trust the Hijacker

Not being inherently harmful does not make Browser Hijackers more desirable – quite the opposite. Even if they aren’t actual viruses, they are still perfectly capable of causing a number of issues that you surely don’t want to be dealing with.

  • Police Block Virus, apart from modifying your browser without you giving it your permission, might also fill it with various pop-up ads, banners and box messages. They can be extremely difficult to get rid of and if you click on any of them, there is some chance that you might get redirected to some shady website with a questionable reputation.
  • Many Hijackers are capable of modifying the ads they display in accordance with the individual’s personal tastes and preferences. They are able to achieve that by gathering data directly from the user’s browser (recent searches, website visits, etc.) which is certainly something you don’t want to be happening to you.
  • Hijackers might also have effect on the performance of your machine, especially if the PC is not very powerful. RAM and CPU spikes caused by Police Block Virus can significantly slow down your machine and sometimes lead to freezes and maybe even system crashes.

Be responsible

A Hijacker, though unpleasant, is one of the lesser problems that you might encounter if you aren’t careful. In order to keep your PC safe in future, make sure to remember and utilize the tips from the next short list we’ve prepared for you.

  • Avoid websites with questionable reputation and stick to ones that you are certain that you can trust. Also, be very careful with what you download and where from.
  • Never open emails or interact with other online messages if they look fishy and dubious. Bear in mind that currently, online spam is one of the top most widely spread methods for spreading unwanted and potentially dangerous programs.
  • Go to your browser’s settings, look for an option that enables automatic download of files and make sure it is disabled.
  • If you want to install a new program, first take a careful look through the installer in order to determine if there are any other applications bundled with the main software. If there are any added applications that seem shady and might turn out to be a Hijacker or some other form of undesirable software, disable them before installing the program that you want. File bundles like that are a very effective way of installing Hijackers onto people’s computers.
