Androidrecaptcha.info Ads – Detailed Overview
Pdfsrch.com is a website used for the realization of different advertising campaigns. It interrupts browsing sessions in order to display deceptive offers. Its goal is to persuade users to complete a process of a few actions so that its operators can become able to deliver push notifications with additional sponsored content; obtain sensitive credentials; deliver a rogue software; etc.
Bogus websites like Pdfsrch.com are often related to system security issues. Typically, ads like these generated by Pdfsrch.com start flooding trustworthy web browsers (Chrome, Firefox, Safari, IExplorer, Edge, etc.) after the unnoticed installation of a potentially undesired program like adware.
Unfortunately, there are many free third-party applications across the web that are promoted as useful tools while they aim to deliver a potentially unwanted program on computer systems. These apps come with extras or the so-called “special offers” in their installers. The tricky part is that their installers rarely disclose any details about featured extra apps and this way trick users into giving permission for their installation. Happily, the presence of added PUPs could sometimes be revealed by the information presented in the Advanced/Custom configuration option. So we recommend that you select it every time you see it in an app installer.
The presence of an adware program on the system may result in unnoticed activation of different tracking technologies that aim to spy on your online activities. By doing this, the program sends valuable information to its owners. They, in turn, send back ads that match your online interests. The appearance of other types of annoying online ads such as pop-ups, pop-unders, banners, etc. may be related to the presence of adware on your system. Beware because some of these ads may open websites that compromised and set to deliver malicious software directly on the PC.
For the sake of your online security, it is highly recommendable that you scan your affected system and ensure that no suspicious or potentially harmful files are running on it.
