NetGuard is marketed as a website reputation checker, supposedly helping users determine the safety of web pages and detect potentially malicious websites. While this may sound like a useful tool, NetGuard has been flagged as a potentially unwanted program (PUP) due to concerns over its distribution methods and potential risks to users.
The main issue with NetGuard is that it can be distributed through unreliable or deceptive installers, sometimes bundled with adware, browser hijackers, or other unwanted software. Users who install it through such sources may experience a range of problems, including intrusive ads, browser redirects, reduced system performance, and privacy risks.

How Does NetGuard Work?
NetGuard claims to analyze website security and protect users from phishing and malware-laden websites. However, if installed via third-party installers, it might introduce more risks than it prevents. The software may collect users’ browsing data, display persistent ads, or even push users to upgrade to paid versions or install additional programs.
Why is NetGuard Considered a Potentially Unwanted Program?
Although NetGuard itself is not classified as a virus or ransomware, the way it is distributed and functions on infected systems raises several concerns:
- Bundled Installations: It is often installed through deceptive software bundles, meaning users may unknowingly install additional unwanted software.
- Privacy Issues: It may collect browsing-related data, IP addresses, and system details, which can be sold to third parties.
- Annoying Pop-ups & Ads: Users may experience intrusive notifications urging them to install other applications or pay for premium versions.
- System Performance Issues: The program may consume significant system resources, leading to slowdowns and crashes.
- Security Risks: If bundled with malware or adware, it could expose users to further cyber threats.
How Did NetGuard Get Installed on Your System?
NetGuard is commonly distributed via free software bundles and deceptive ads. When downloading free programs from unverified sources, users often overlook the installation process, leading to accidental installation of additional software, including NetGuard. Additionally, some users may install it from unofficial websites, believing it to be a legitimate security tool.
To avoid installing potentially unwanted programs like NetGuard, follow these tips:
- Always opt for the “Custom” or “Advanced” installation method when installing software. This allows you to see what extra programs are included in the package.
- Avoid clicking on pop-up ads that claim your system is at risk.
- Download software only from official sources and developers’ websites.
- Use a reputable security program to detect and block PUPs before they install.
