What is Showad.js/Ads.pubmatic.com? How does it work and affect our system?

If you have come across this article, you may have experienced some technical problems with unwanted and maybe aggressively appearing advertisements in different forms on your computer screen. If you can match this description to your issues, you probably need to deal with Showad.js/Ads.pubmatic.com. Actually, Showad.js/Ads.pubmatic.com is a kind of Adware. The information below will certainly help you understand the nature of your problem and manage to deal with it easily and for good.

You may wonder what exactly Adware is. Just as the name indicates, Adware is a term used for a lot of various kinds of adverts that appear on your computer. Adware is a software that is programmed to generate a banner, a pop-up advertisement, or some other form of an ad. Sometimes it’s quite obvious, other times much more subtle and you may have no clue that programs or tracking cookies may have been integrated into your system browsers (Chrome/Firefox/Explorer/Opera… etc.).

Adware is used by the ones who have created it to make money. The adware threat to your computer may depend on what exactly has been coded into the advertising. Most of the times, it might simply be an extreme annoyance that produces pop-ups, pop-unders or banners. More rarely,   the potential threat could be more serious, because the ads may have been coded to track your personal browsing history and sell the data to 3rd parties, or to download other Adware to your computer without your clear consent. It is essential to point out that most Adware is not a virus or other form of malware, but just a disturbing marketing tool. It cannot steal personal information about accounts, banking details or passwords, it may just use your most common Internet searches to guess and promote whatever product or service you may want or need.

Adware and its nature

Like most Adware, Showad.js/Ads.pubmatic.com will look to provide ads based on your personal surfing habits. Showad.js/Ads.pubmatic.com may potentially track your movements on the net and collect information about your searches and personal preferences. In a way it may feel like an extensive research of where users go and what exactly they might be looking for. Some users could perceive such activities as an invasion of their privacy. That is why it is so important to detect Showad.js/Ads.pubmatic.com and remove it as soon as possible. When you uninstall adware from your machine, you remove the possibility of the vendors to follow and try to guess your possible browsing activities on the Internet.

In general, Showad.js/Ads.pubmatic.com comes as an attachment to freeware or shareware software. When you install such software, it may start displaying advertisements. You could be able to tolerate such a behavior, after all, you did get that desired software for free.

Always read the End-User License Agreement, to check exactly what you are agreeing to for the chance to use their software. A great number of people just click “yes” and have no clue that they have just agreed to install an Adware-type of software.
