What is it? Microsoft's windows runs on a
large number of PC's. Traditionally Windows had bugs that would permit its
security to be compromised allowing PC's to be infected with malware or
causing it to crash or misbehave in some other way.
However with the common use of Internet
rising, it has become increasingly critical that these vulnerabilities are
quickly identified and patched.
When in the past you had to download files
from the Internet to install them on your PC's, today this process is
largely automated through windows updates. These days windows updating
process can be automated entirely by turning on automatic updates.
What happens when you install bug fixes
is that a hole (defect in OS software) is patched so that a worm or any
other kind of malware cant use a particular bug to infect that PC. Hence
you eliminate a large enough issue by keeping the windows always updated.
When vulnerabilities are left without being patched, that's equivalent to
inviting trouble.
Other operating systems such as Linux,
Unix and Mac has bugs too. Hence do not presume that you will be safe if
you use any other Operating system. Windows faces the maximum threat also
due to its popularity.
Updates to other software:
Apart from Operating System updates, there are other software's which has
vulnerabilities too. MS Office is one example. Although these are
comparatively few, you need to keep a watch on the security vulnerability
of other software's too.
Solution:
Updating the Operating
Systems
