The malicious software  can do this without even having to run as an Administrator.<br \/>\n.<br \/>\n.<br \/>\n.<\/p>\n<p>The researchers found exploitable versions of this vulnerability in  every program they tested, including products from McAfee, Trend Micro,  and Kaspersky. In fact, the researchers said that the only reason that  they found exploits in only 34 products was that they only had time to  test 34 products (Microsoft, for its part, believes that its security  software is not affected, but is still investigating the issue). Many  others may be vulnerable too. They also developed a toolkit dubbed KHOBE  (&#8220;kernel hook bypassing engine&#8221;) to allow the rapid detection and  exploitation of such flaws.<\/p><\/blockquote>\n<p>As far as I can tell, if your computer does not have a multicore CPU, then it is unlikely that this flaw can be exploited.<\/p>\n<p>Maybe I have good reason for not updating my machine.\u00a0 And to think how often I have complained that I let the salesperson talk me out of buying a dual core machine the last time I upgraded.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Follow this link to information you&#8217;d rather not know about how vulnerable your computer may be.
