SpyBlock belongs to the category of Potentially Unwanted Programs, also known as PUPs.
PUPs are programs that, due to their features or means of distribution, can affect users' consent, awareness or control over operations like:
- Modifications carried out on the computer.
- Behavior of the program.
- Processing of personal data.
The evaluation criteria of PUPs are based on the proposals suggested by the Anti-Spyware Coalition, organization of which Panda Security is a member.
SpyBlock prevents access from programs to websites of several companies related with security tools (antivirus programs, firewalls, etc.).
SpyBlock redirects attempts to access web pages of certain banks to spoofed pages, with the aim of logging information entered by the user in these pages.
SpyBlock redirects attempts to access several web pages to a specific IP address.

- Exploiting vulnerabilities with the intervention of the user: exploiting vulnerabilities in file formats or applications. To exploit them successfully it needs the intervention of the user: opening files, viewing malicious web pages, reading emails, etc.
- Via Internet, exploiting remote vulnerabilities: attacking random IP addresses, in which it tries to insert a copy of itself by exploiting one or more vulnerabilities.
