Experts at SophosLabs™, Sophos's global network of virus and
spam analysis centers, have successfully protected against all the
Trojans using proactive technology.
The latest Bagle Trojans, all of which are very similar to each
other, attempt to infect insufficiently protected Windows
computers. If infected, the Trojan will attempt to turn off
anti-virus applications, delete files off the computer, drop more
malware, download code from the internet and reduce system
Sophos has not received a large number of reports of any Bagle
variant; however, when added together, they account for 13.9% of
all reports in the last 48 hours. Trojans, not being able to spread
on their own, require human intervention and normally depend on
being spammed out or posted to newsgroups.
Sophos's proactive Genotype™ technology was capable of detecting
the Trojan horse proactively (naming it as Troj/BagDl-Gen),
defending customers' computers without requiring an update since 16
March 2005. Sophos PureMessage, Sophos's consolidated email gateway
solution which defends businesses against both spam and viruses,
can also block the spam messages sent by the Trojan horse.
