That should read "isn't capable of stopping anything but the most common or basic" Too early in the morning for email here. On Wed, May 6, 2009 at 11:59 AM, Michael Graham <jmgraham () gmail com> wrote:
Unfortunately, anti-virus isn't capable of stopping the most common or basic of malware. Simply moving the hostile payload beyond the first hundred bytes or so of an executable is enough to prevent most AV software from detecting/alerting. Beyond that, the number of third-party applications with serious vulnerabilities (Acrobat seems to be this year's problem) means that relying on anti-virus to prevent malware infection is likely to result in an unpleasant surprise.

Mcafee viruscan 8.7 blocks programs from making outbound connections on port 25 by default so how did the virus get past ? I verified that the mcafee was working since I could not telnet to any mail server on the internet via port 25. ------------------------------------------------------------------------ This list is sponsored by: InfoSec Institute Learn all of the latest penetration testing techniques in InfoSec Institute's Ethical Hacking class.
