What is FirSeriaInstaller?

If you see FirSeriaInstaller working on the background of your computer’s system, we recommend running a full system scan because it’s obvious that your computer has been infected with an adware-type program. Probably you doubt where this dubious program came from. FirSeriaInstaller has been classified as a potentially unwanted program (PUP) due to the fact that it is capable of infiltrating random computers via various freewares and sharewares. It is compatible with all most popular web browsers, including Google Chrome, Mozilla Firefox and Internet Explorer, so beware that switching web browser from one to another won’t help to avoid operations that this adware implements. In fact, FirSeriaInstaller is not a malicious program that can ruin your PC’s operating system. However, it may corrupt your web browser’s settings, track your browsing activities, show pop-up ads and fake pop-up alerts, and slow down your PC’s performance significantly. You may think at first that the worst what this program can do is to slow down the system and display various advertisements that appear in an extremely annoying manner of pop-ups, banners, in-text links and so on. Yes, we agree that it’s annoying and interferes your browsing seriously. Unfortunately, that’s only a tip of an iceberg. ‘Ads by FirSeriaInstaller’ may cause much more serious problems, such as infiltration of malicious programs on your computer. Since various third parties seek to promote their products with the help of this adware, it installs tracking software and tracks user’s browsing activities in order to adjust advertisements according to user’s interest. Unfortunately, no one knows what third parties are involved in such activity and what kind of websites they wish to promote. As a consequence, there is a high probability that FirSeriaInstaller redirects may reroute you to unsafe websites used for spreading malicious programs and trick you into installing one. Therefore, do not hesitate and remove this potentially unwanted program from your PC as soon as possible.

How can FirSeriaInstaller hijack my computer?

In most of the cases, FirSeriaInstaller travels bundled with other applications that can be downloaded from the Internet for free. Therefore, when you download and install some freeware, there is a chance that this browser plug-in will be installed alongside without you even being aware of it. To avoid this happening, select free programs more carefully and avoid downloading software from suspicious-looking websites. If you do not have any other option, then you have to install your chosen program with extreme carefulness. Select Advanced or Custom installation option and NEVER skip any steps by simply clicking the ‘next’ button all the time without reading the whole information first. Look for various check boxes that suggest installing additional programs that are already checked for you. If you notice at least one containing unfamiliar programs that are going to be installed alongside, do not allow their installation, because it can possibly be FirSeriaInstaller or any other potentially unwanted program. If you have already noticed this app on your PC, follow the instructions down below.
