Steer Clear of Fake Antivirus 2010

One of the most common computer problems in the last few weeks has been a recent outbreak of “Fake Antivirus 2010.” This is a fake antivirus and antispyware program that infects your computer via the internet. There are a few different ways you can get this. One of them is by clicking on internet ads. You can also get infected by simply visiting certain websites or using file-sharing programs like Kazaa or e-Donkey looking for illigitimate ways to install software that must normally be purchased before it is installed. A large percentage of the programs that are found on these file sharing networks are infected with spyware and trojans.

Security Corner – Protect Your Network With OpenDNS.

With recent threats to our digital security like the Conficker worm, it is more important than ever to strengthen your network’s defenses. There is a fantastic free service specifically designed to boost network security called OpenDNS; it is free and will protect you from many future attacks if you just take a moment to set it up. The OpenDNS website provides simple instructions for changing your DNS server on a single machine or router (so that the change affects ALL networked computers) and even includes a video tutorial. What does this accomplish? Making the change will cause your computer to go to an OpenDNS server to look up the domain names for the sites you visit instead of the DNS server provided by your ISP; the OpenDNS server has the ability to deny you access to known phishing and hacking sites. There is a content filter that will deny access to any type of questionable site you do not want your child visiting and the ability to report network traffic is built right in.
