Your computer may be acting funny today; and access to the Internet could be lost thanks to a malicious software that your computer may have, and you don't even know it. Dallas Standly, a member of the Geek Squad at Best Buy in Bend tells our news partner, News Channel 21 that malware can be easily installed in your computer without your knowledge. And if you don't have a good virus protection program, your computer could be affected. "They're going to start kind of systematically shutting down computers that are still kind of spreading this particular kind of malware. It won't be all types of malware, but this one, that affecting that type of D.N.S. Server, will be taken off the Internet." Just under 250,000 computers are expected to lose their Internet connection to the World Wide Web today. Symptoms include a super slowdown or your computer acting in ways you don't want it to. You can check to see if your computer is infected by visiting: www.DNS-OK.us. If your computer is infected, a red image will appear with instructions to remove the malware.
