Well, one thing is for sure. If you use the internet everyday, you are going to encounter viruses. There is no way around it. The best way to deal with viruses is to block them from entering your computer altogether. This is done with firewalls and with adequate and updated anti-virus software.

But what if it's too late, and what if a virus has already entered your system? Well, it isn't always too late. But it is always critical when an actual virus as opposed to malware or adware has entered your system. This is because oftentimes viruses are destructive as well as prolific. In other words they will either destroy your data, destroy your operating system, infect every computer on your local network or send 10,000 spam emails an hour pretending to be from every friend in your email address book. Or, do all of this at the same time.

One of the most important considerations for your business enterprise is network and systems security. In these times it can be especially tedious maintaining security with the challenges of the Internet and social networks, gigabyte sized free email services and small portable storage devices which can easily transport over 100 gigabytes of data.

Let's start with the Internet. Ever since the "code red" worm in July 2001 nothing has been quite the same in network security. That day marked the beginning of a new threat from the outside in through the Internet. What made this threat unique was that it came into the enterprise through trusted firewall ports.
