One of the most important functions is that trojans already running can be detected and deleted. A huge database on trojan process allows PDG to find running trojans The registry. Most trojans pretend to be system files, trying to escape the scan. All the files on your hard drive. Yes you do, if you connect to the Internet.
Most trojans use the Internet as a way of self-distribution.
But trojans are more dangerous and destructive. PDG is specially designed to eliminate trojans. Some anti-viruses may occasionally find trojan horses, but even if this happens, you will have no idea how to get rid of it. An anti-virus is not any help in this situation. PDG will do it all for you.
