Information about the Blaster Worm

A virus or worm known as Blaster is currently spreading across the Internet. This virus may infect the following Microsoft Windows products:

Additional information is available at http://www.cert.org/ . This is the site of the Computer Emergency Response Team, a well-known centre of Internet Security expertise.

An important point to note is that this virus is spreading via means other than email. This means that you may be attacked unknowingly while browsing the Internet.

Applying the Microsoft fix will prevent you from being infected by this virus. However, if you have already been infected applying the fix will not remove the virus, but it will prevent reinfection once you have cleaned it from your PC.

An infected PC may not show any noticeable signs of infection. However, it has been reported that some PCs are randomly shutting down, rebooting or producing error messages. The virus installs the file "msblast.exe" onto your PC, which you may search for using Microsoft Windows search facilities.

The use of an up-to-date Antivirus program could also alert you to the existence of this virus on your PC. You should contact your vendor if you are in any doubt as to the status of your Antivirus definition files. In addition, the use of a personal firewall might offer you protection from this virus, but this depends on its configuration. You should seek further information from your documentation or vendor of the supplied software if necessary.

The following Antivirus vendor websites provide information and tools for removing the virus from your system:
