Using Ubuntu to Delete Windows 7 Trojans

December 26th, 2009 No comments

My broadband service provider informed me that my network IP address was issuing massive amounts of spam email. To my horror I realised it was my own PC. I’d recently done a lot of work double checking my PC with both Sophus and AVG so I thought I was clean. The Service provider recommended that I use Avast and that I do a DOS Level Search from Boot. The advantage of doing this is that viruses and Trojans have a lot less chance of hiding themselves somewhere in Windows. Well Avast spotted quite a few problems including an iframe Trojan in a back-up of a website but nothing that solved my problem. Well I ran avast several times and then it asked to do another Boot search and then alerted me to a trojan in a driver file micbd.sys c:\windows\System32\drivers\micbd.sys unfortunately the Trojan would not let me delete it from DOS or from Windows whatever, so I used my old trick I booted from a Ubuntu CD this gave me access to the Windows File System and I deleted the offending micbd.sys driver. Now have fought off a couple of Trojans recently I can give you a clue in both cases the first thing I noticed was that the virus checker listed the eventual file as UNOPENABLE

So two tips you may find useful:-

  • Use a Ubuntu DVD to rescue, backup, or repair a damaged Windows System (do not install Ubuntu boot from the CD)
  • When looking for a Trojan or Virus on your Windows PC be very suspicious that your virus checker marks as inaccessible

LED Lighting Taking Over the World

December 13th, 2009 No comments

LEDs are taking over in the following sectors:-

  • LED Flat Screen Televisions are actually LCD TVs which use LEDs for backlighting.
  • LED Flashlights or Torches now totally dominate this sector
  • LEDs for general lighting
  • LEDs for Street Lighting
  • LEDs for Traffic Lights

LEDs are taking over because they are incredibly reliable with a life usually easily longer than the expected life of the equipment. They also are more efficient causing less heat dissipation problems. They are very popular for helping to reduce global warming and other Green issues.
