My browser behaves weirdly and has ads all over it – is this a virus?

Browser ads can be caused by various reasons. However, there’s no need to worry because in the majority of cases the reason is not a virus or some other kind of malicious program. First of all, we need to make it clear that online ads are often integrated within the websites themselves. It’s just that some pages’ ads are more intrusive and annoying than others and that makes it seem like there’s something wrong with your PC. Nonetheless, if there are obstructive pop-ups and banners on every webpage that you open, then you probably have had an adware type of program installed on your machine. The Dozen Search “Virus” is such a program – it is a newly released browser add-on, which falls under the category of adware programs. Since most of them are pretty similar to one another, what applies for the Dozen Search “Virus” will apply for other adware as well.

How bad is the Dozen Search “Virus”?

Firstly, we need to make it clear that these programs are not viruses. Unlike malicious software like Trojan Horses or Ransomware, adware are fairly harmless. All they do is generate those annoying ads, that prevent you from effectively using your browser. However, know that some of the ads might actually be potentially dangerous. There’s a possibility that, by clicking on any of the pop-ups, you may get redirected to some illegal and harmful website. It is also possible that another unwanted program might start downloading itself onto your PC. Page redirects caused by the adware may even occur without you doing anything. If you see this happening, make sure that you quickly close the newly opened page. Do not interact with the contents of those pages – no need to risk your PC’s security. Besides, those pages hardly ever have anything useful for you.

What’s the purpose of the Dozen Search “Virus”?

For the most part, adware programs are used to gain revenue for their developers. This is done via the pay-per-click method. The more adds users click on, the greater the revenue. There are some of them that could even track your browsing history. This may sound illegal and harmful, but worry not – the adware usually cannot access any important data. Besides, the main reason for the tracking of your browser activity is so that the intrusive program can customize the ads, banners and box messages it displays, according to your preferences. It is true that some of the more aggressive adware add-ons may sell the data acquired from your browser but, again, there’s hardly ever any essential information that they can access.

Dealing with Dozen Search

With all of that being said, it should be obvious why Dozen Search is considered a unwanted program and should be removed from your computer as soon as you notice its presence. Below this article, we’ve provided you with a guide on how to have the intrusive software uninstalled and removed from your PC. However, before we get to it, there’s some more important information, that you should know about the unwanted program – namely how it gets in your system and how to prevent this from happening in the future.

There are many distribution methods for adware programs: illegal torrents, file-sharing sites, spam e-mails etc. Sometimes annoying add-ons are even pre-installed onto the machine, so that when you buy a new PC, it is already filled with various programs (possibly adware) that in many cases have no real use. However, the most effective and widely-spread method remains the file-bundling. When the adware is bundled with a program, it gets installed along that program. We need to make it clear that this is usually a legal method. File-bundling is very common especially among cheaper or free programs. The reason why people fail to prevent the installation of Dozen Search is because they usually go for the regular installation, which installs all added content along the main thing. This is a mistake. Unless you are 100% certain that there’s nothing added to the program you’re attempting to install, always opt for the advanced installation settings. This will give you the opportunity to customize the installation process and choose whether the added contents will get installed along the main program. Find the list with add-ons and uncheck everything that you consider unnecessary or unwanted. This is important to remember since if you often install new programs and always go for the regular installation, your PC will soon get filled with all sorts of useless bloatware, that will significantly reduce the productivity and well-being of your machine.
