Microsoft has released a patch for CVE-2007-1765 (aka CVE-2007-0038).  Anyone using a vulnerable system should install this patch ASAP. Hundreds of websites have been found to be hosting exploits, with thousands of websites and spam leading users to that malicious code.  The number of attacks is likely to rise steadily for several weeks if not months.  Exploit-ANIfile.c detection quickly rose to the number one spot on our consumer regional virus tracker chart for Asia, over the weekend.  We can expect the detection of this exploit to top the charts as the most widely seen exploit over the next few weeks as well.  Currently it is taking up the number six spot on the worldwide chart:
