The results of an online
test conducted by U.K. anti-virus firm Sophos found that more often than
not, PC users don't install Microsoft's monthly patches.
The results, released on Monday, were gathered from 40 days' worth of data
from a sample group of 580 PCs in corporate environments, 80 percent of which
failed one or more basic security tests.
Moreover, 63 percent were found lacking
at least one Microsoft patch on the OS level, the Office and application levels,
or the browser and media player component levels.
