8.6.5. LSP Viewer
The
LSP Viewer
dialog shows a list of Layered Service Providers (LSP).
A
Layered Service Provider
(LSP) is a system driver linked into the networking
services of the Windows operating system. It has access to all data entering and
leaving the computer, including the ability to modify this data. Some LSPs are
necessary to allow Windows to connect you to other computers, including the
Internet. However, certain malware applications may also install themselves as an LSP,
thus having access to all data your computer transmits. Therefore, this review may
help you to check all possible LSP threats.
Under certain circumstances, it is also possible to repair broken LSPs (
for example
when the file has been removed but the registry entries remain untouched
). A new
button for fixing the issue is displayed once a repairable LSP is discovered.
To include Windows LSP in the list, uncheck the
Hide Windows LSP
checkbox. The
Back
button switches you back to the default
AVG user interface

8.7. Firewall
Firewall is a system that enforces an access control policy between two or more
networks by blocking/permitting traffic. Firewall contains a set of rules that protect
the internal network from attacks originating outside (typically from the Internet) and
controls all communication on every single network port. The communication is
evaluated according to the defined rules, and then either allowed or forbidden. If
Firewall recognizes any intrusion attempts, it “blocks” the attempt and does not allow
the intruder access to the computer.
