Why antivirus software is so important for online safety?

Internet is not a regular computer network, it is a combination of loosely connected networks, routers, and computers around the globe. The fascinating thing about this global network is that every network node (computer, gateway, etc.) is accessible from any other node in every country, on each continent. Thus, businesses and private users can reach any public server on that network regardless its geographic location or time of day.

However, as the Internet grows, along with the easy access to information come new threats and possible security risks. Often, data stored on a server is targeted by hackers, who try their best to crack security and to sniff out flaws in software and hardware that would allow them access to confidential information.

The more information is stored online, and the more new computers and users connect to the Internet each day, the higher the possibility someone will attempt to compromise servers' security.

With Internet, criminals do not need to be physically present at the crime scene. They can launch remote attacks from virtually any place, including countries with poor law enforcement and liberal jurisdictions. While they crack on a server, they often conceal the traces of their dubious activity by deleting access log files or connecting by a proxy.

This site is intended to all server administrators, security geeks and enthusiasts, who want to learn about online security dangers and how to counteract them.

Online security and antivirus software is one of the hottest topic in the recent months due to high virus activity and several worm strikes such as recent Conficker Worm fool's day attack. Browse this site to examine dangers and learn about malicious software and how to protect your PC from remote attacks, hackers and viruses.
