AVG Free Detection Technologies
The Anti-Virus component of AVG Free uses the following technologies to detect
computer viruses:
- Scanning – searching for character strings that are characteristic of a given virus
- Heuristic analysis – dynamic emulation of the scanned object’s instructions in a virtual computer environment
- Generic detection – detection of instructions characteristic of the given virus/group of viruses
Where just a single technology might fall short of detecting or identifying a virus,
AVG Free combines several technologies to ensure that your computer is protected.
AVG Free is also able to analyze and detect executable applications or DLL libraries
that could be potentially unwanted within the system. We call such threats
Potentially Unwanted Programs (PUP). Such a program could, for example, be
some kind of spyware, adware etc. Upon the user’s request, AVG is able to remove
such programs or block access to them.
Furthermore, AVG Free scans your system registry for suspicious entries,
temporary Internet files and tracking cookies, and allows you to treat all potentially
harmful items in the same way as any other infection.
