What is Security Guard?
Security Guard is a dubious application identical to Win Security, Safe Browsing, Win Guard, and many others.According to the developers, Security Guard significantly improves Internet browsing security - "Security Guard This browser application is designed to secure your browser, while surfing the internet".
On initial inspection, this app might appear legitimate, however, it often infiltrates systems without users’ consent. In addition, Security Guard generates intrusive online advertisem*nts and tracks Internet browsing activity. For these reasons, it is categorized as a potentially unwanted program (PUP) and adware.
This potentially unwanted program continually monitors browsing activity by gathering various browsing-related information such as geo-location, language, IP addresses, operating system, website URLs visited, search queries, and so on. Some of this collected information might be personally identifiable.
Furthermore, it is later shared with third party companies who misuse personal data to generate revenue. This behavior can lead to serious privacy issues or even identity theft. Security Guard employs a 'virtual layer' to generate various intrusive online advertisem*nts. The virtual layer enables placement of third party graphical content on any visited site.
Therefore, none of the displayedads originate from users' visited websites. Third party advertisem*nts often conceal underlying web content, thereby significantly diminishing the Internet browsing experience.
Some may also lead to an infectious websites and, thus, even accidental clicks on them might result in high-risk adware or malware infections. For these reasons, Security Guard should be uninstalled immediately.
Security Guard is not the only application falsely claiming to enhance the Internet browsing experience. There are hundreds of adware-type programs also giving fake promises simply to trick users to install. After system infiltration, none provide the functionality promised.
Applications such asFlashBeat, Provider, and Selection Tools, track users'Internet browsing activity and generate intrusive online advertisem*nts. All adware is designed to generate revenue for the developers - it is useless for users.
How did Security Guard install on my computer?
Security Guard is free for anyone to download on its official website, however, many users install this app inadvertently.
The developers know that users often rush the download and installation processes and, therefore, intentionally conceal installation of potentially unwanted programs within the 'Custom' or 'Advanced' settings of these procedures. By skipping this section, users expose their systems to risk of various infections.
How to avoid installation of potentially unwanted applications?
Installation of applications such as Security Guard can be prevented by taking two simple steps. Firstly, closely analyze each step of the software download and installation processes using the 'Custom' or 'Advanced' settings. Secondly, cancel all bundled software listed for download/installation.
