Microsoft has released a beta version of its Windows Defender antivirus tool that works even when computers are so badly infected that they are unable to fully access the internet.
The program allows users to boot their sick machines off of a CD, DVD or USB flash drive and use the most up-to-date definitions to fight the infections. It's of particular use for removing certain types of malware that make it hard or impossible to access security and antivirus sites. Computer crooks often try to prevent victims from cleaning up their PCs by preventing them from accessing those sites. Other times, Windows gets so corrupted that network connectivity no longer works.
