The Novarg Virus Can Be Caught by GFI's Gateway-Level Trojan Scanner BEFORE Anti-Virus Vendors Release Updates Against It - The New Novarg Virus Shows Once Again That Anti-Virus Engines Are Not Enough

London (ots)

Novarg (also known as Mydoom and Mimail.R), the
latest email virus to threaten the security of networks worldwide,
highlights yet again that it is not enough to rely on anti-virus
protection alone. The time it takes for anti-virus vendors to
discover a virus and issue an update against a new virus is too long
and allows ample room for infection and distribution. GFI's Trojan
and Executable Scanner, on the other hand, catches Novarg and other
new viruses immediately -- before their signatures are issued.
The difference between a virus engine and a Trojan and executable
   scanner
Because anti-virus software is signature-based, it can only detect
known viruses and Trojans, and is therefore unable to detect new
viruses such as the Novarg as soon as they are released. GFI
MailSecurity's Trojan and Executable Scanner takes a different
approach: Rather than relying on signatures, it uses built-in
intelligence to rate an executable's risk level. It does this by
disassembling the executable, detecting in real time what it might
do, and comparing its actions to a database of malicious actions.
This way, GFI MailSecurity can detect unknown viruses and Trojans
before they enter the network -- and before anti-virus engine vendors
have issued signatures against them.
"A couple of hours too late"
"If a vendor takes a couple of hours to issue an update against a
new virus, this is often a couple of hours too late. By then, the
damage is done. All it takes is for one machine on a network to be
infected. The virus then propagates to that network and others,
causing great damage," explained David Vella, GFI MailSecurity
Product Manager. "Organizations need to take a proactive approach to
protecting themselves and should install gateway-level protection
against one-off and unknown email threats and Trojans, as well as
standard virus scanning software."
It is for this reason that GFI MailSecurity for Exchange/SMTP --
GFI's email content security and anti-virus product for Exchange and
SMTP mail servers -- incorporates a number of features against email
threats, including the Trojan and Executable Scanner.
Novarg.A is reported to be infecting a vast number of computers.
This worm is an executable that travels in the form of an email
attachment, and it requires users to run the executable to be
activated. The worm spoofs the email sender and the executable is
usually compressed inside a zip file. It also launches a Denial of
Service attack on www.sco.com and opens a backdoor on the infected
computers. The GFI Trojan and Executable Scanner feature is able to
catch Novarg.A because this infringes the scanner's "CheckUPX" rule;
the worm is compressed using a UPX packer, which indicates that such
an executable might be malicious. Further information is available at
