Internet security should be of the utmost concern in 2010

With ongoing concerns over terrorist attacks from extremist groups. My thoughts reach towards internet security.  Everyone needs to be concerned about their own internet security and should have antivirus software running on their computer.  Your computer may come under attack in many forms.  You could quite easily download a photo from the internet,  however when you open it  you could find it has a program hidden which is going to be used for malicious intent. Some of the common programs used are trojons,viruses,malware, worms and bots.
