Virus, Spyware, Rootkits...

avast! Pro Antivirus will of course protect you from viruses, but the program will protect you from many other dangers as well. You will be protected against spyware that want to spy on you and your behaviour in order to send the information to the maker of the spyware. This is mostly a privacy issue. You will be protected against the much more serious threat from rootkits that will hide itself deep in your windows in order to steal your log in codes to your online bank or other sites where they can steal your valuables, or from where they can make it possible for a hacker to remote control your computer.

You will also be protected against malicious scripts on websites and against malicious attachments in e-mails.

At the Forefront of the Virus War

Usually virus makers have an advantage compared to the makers of antivirus programs. In the arms race the virus comes first, then the antivirus makers has to discover the virus, make a definition file, and then distribute the definition file to their users. Thanks to a heuristics filter, avast! Pro Antivirus can identify a virus, even if it is not in the programs definition file, thus it is able to stop an unknown virus!

avast! Sandbox makes it possible to run potentially exploitable programs like your browser in a safe virtual environment. That way an exploit of the program cannot harm the rest of your system. avast! Pro Antivirus also includes a code emulator that can test the behavior of a suspicious program without actually running it. Thus checking if the program is malicious or not.
