SentryBay locks down e-mail viruses

The rise of fast-spreading e-mail viruses is driving the need for software
that does a better job than conventional antivirus products of stopping
viruses from replicating themselves.
To that end, SentryBay Corp. took the wraps off ViraLock, software that
blocks e-mail viruses from spreading. The software encrypts addresses found
in e-mail programs so viruses cannot be replicated, according to company
officials. ViraLock was unveiled Sept. 10 at the Networld+Interop trade
show in Atlanta.
ViraLock is the missing half of virus protection, said Marcus Whittington,
vice president of marketing for Newport, Calif.-based SentryBay. Most antivirus
software focuses on detection and prevention and has to be updated to address
new strains of viruses. A growing number of viruses can enter computers
without being detected, so ViraLock prevents the virus from leaving the
system, Whittington said.
ViraLock is positioned between the e-mail program and the server, intercepting
e-mail being sent from and received by a desktop. The software automatically
encrypts all existing e-mail addresses and those added later to the address
book as well as folders of the e-mail program. Outgoing messages, intercepted
when the user sends e-mail, are decrypted before being passed on to the
mail server. A virus searching for e-mail addresses won't find any valid
addresses, and thus can't replicate itself.
Because the "focus is on [blocking] replication, users still need antivirus
and firewall" protection, Whittington said.
As a result, ViraLock works with virus protection software such as Symantec
Corp.'s Norton AntiVirus and McAfee.com Corp.'s VirusScan and supports Microsoft
Corp. Outlook and Outlook Express. Future versions will support Netscape
Communications Corp., Qualcomm Inc.'s Eudora, Pegasus Mail and Juno Online
The company is developing an enterprise version, scheduled for availability
by year's end, for e-mail servers that will support Microsoft Exchange,
Oracle Corp. and Lotus Development Corp. Notes. Future versions of ViraLock
will prevent the spread of viruses through instant messaging, personal digital
assistants, and mobile phones.
ViraLock will be available for download Oct 15 via SentryBay's Web site
(www.viralock.com). The product costs $19.95 for
a single-user license.
