PC Purifier is NOT a virus!

Let’s get this out of the way. PC Purifier is in no way a computer virus! PC Purifier is a piece of software, marketed as a PC optimization tool. Its alleged purpose is to clean out any junk files from your system and clear valuable space, while also serving as protection against viruses and various malware infections. However, despite its seeming usefulness, this software is widely considered to be a potentially unwanted program or PUP. For one, it can be quite annoying, as we’re sure you’ve come to notice by now. The moment PC Purifier is installed on your system, your screen becomes flooded with popups and advertisements of various kinds. The vast majority of popups is aimed towards persuading the user to purchase the full version of the software, download some other program or install a given update. You are also very likely to start seeing in-text links, as you browse the web, which is also a form of advertising and a typical characteristic for other unwanted programs, such as adware and browser hijackers.

Aside from its intrusive behavior, there’s also the factor of its distribution, which also contributes to PC Purifier landing the title of a PUP. Chances are you probably don’t even know how you ended up with this program to begin with. In fact, very many users who’ve been faced with it reported having no recollection of ever interacting with this software before it unexpectedly just appeared on their computer. There are a number of ways you could have unknowingly installed this program, but the most common and effective means of spreading it is through a technique known as program bundling. This mechanism allows software developers to incorporate one program or even a set of programs within the installer of another. This ‘main’ program is usually a piece of freeware or shareware and an typically be downloaded from various shady, not-particularly-trustworthy websites. It can be a torrent site, a file sharing website or some other open source download platform, the likes of which are all but rare on the vast planes of the Internet.

When downloading a bundle, in most cases you will have no idea that it is in fact a bundle. In your mind, you will have acquired some new software, which you will then be eager to install and use. How you install the program of choice, however, is what determines whether you will make your PC home to any other programs as well, or just the one. Also, a good way of getting informed regarding the piece of programming you’ve decided to interact with, would be to read the EULA, which will most probably mention any and all added content. But, as no one really does this, people tend to rush through the installation process, using the quickest options at hand and often without even paying attention to anything in the setup wizard.

How to avoid PUP’s

You’d be surprised to find out how simple it is to actually keep your machine PC Purifier-free and prevent any other unwanted software from getting installed, too. All you need to do is customize the installation process of any new program you’re about to use. By that, we mean going for the corresponding option, which is usually the first step in any setup wizard. The option you’re looking for will normally either be called advanced or custom and that’s the one you should go for. Don’t shy away from it, thinking it includes some detailed technical options that you won’t be able comprehend. That’s not the case – you will simply be shown a list of all the added programs (if any) and from that list you can deselect anything you don’t recognize and don’t want on your machine.
