The Blaster virus and how to get rid of it.

The blaster virus is still infecting thousands of machines across the web. There are now 9 variants of the blaster virus active on the internet and a huge number of machines are still infected and trying to infect others. This virus exploits weakness in Microsoft Explorer and causes annoying problems on your machine. Examples are:

  • Machine reboots over and over
  • Cut and Paste between Office apps does not work
  • Email download in Outlook fails
  • Links don't work on web pages

This virus does not come through the mail instead it comes direct from another PC who uses the same internet provider as you. The only way to stop these worms is to use a firewall. Even if you are using a dialup account you should have a firewall. You dont even need to pay for it, just download the home user version from or and install it. Once you are running a firewall program you will be amazed at the number of attempts there are to hack into your PC - about 50 per hour is average if you include viruses. - It's scary! Get a firewall and be secure.


The only way to keep your machine safe from viruses is to get an anti-virus product. We trust and recommend the award winning Panda Titantium Anti-virus solutions for home users.
