We strongly recommend all our clients
use either:
ESET
Smart security for personal use
& small businesses or Sophos
Antivirus for larger enterprises
We install & configure the software
to provide you maximum protection
Facts
- Depending on the size of your business, a virus
infection could cost anything from £2000 upwards in lost productivity,
downtime and recovery
- Your customers may also be affected if the virus
outbreak spreads to them and their confidence in your organisation
lost
- Approximately 1 in 50 E-mails has a virus so if
you get 20 e-mails a day you risk a virus infection about twice
a week. During most virus outbreaks this ratio is a lot lower &
hence risk is much higher.
- Viruses can also be spread by compromised web
sites distributing malware & Trojans
- Malware authors are using more sophisticated methods
of infection - for example by exploits in Adobe PDF & shockwave
files
- Use the best virus checker you can afford and
update it daily - out of date anti virus software is useless - update
Sophos here
- Be aware that viruses may exploit open ports such
as 444 by blaster and are transmitted by other means than e-mail
- Do not install peer file sharing software such
as Limewire or Kazaa, as these allow uncontrolled access to your
computer
- Antivirus software alone may not be sufficient
- consider using a good malware/spyware program as well
- Treat unfamiliar e-mail with suspicion, particularly
from an unknown sender with a message of a personal nature
- Do not pass on warnings about viruses, most are
false and/or contain incorrect advice, verify
them here.
- Use a firewall, with ADSL a router with a firewall
and NAT translation is essential
- Visit the Microsoft web site and download the
latest security fixes for Internet Explorer in particular as its
a security disaster! FireFox
is a better browser.
- Use a spam
filter on your domain or a product like Mail
Washer Pro to blow away spam and reduce the e-mail being processed
before delivery
- Consider using a secure web browser such as Opera
or Firefox they
are less vulnerable to exploits
than Internet Explorer
- For further information visit our security
page
Server side - but some also be relevant
to standalone
- Block potentially hostile attachments such as
.com .bat .pif .scr & .txt many of which are used for virus
delivery
- Deny access to Kazaa and web sites offering similar
peer file sharing services
- Use a hardware firewall (ie sonicwall), mandatory
if you have a fixed IP address or run a VPN
- Consider the excellent Arxceo
Ally to defend your network
- If you run a network consider deploying a multi
tiered solution
- Scan outgoing as well as incomming mail to prevent
an internal outbreak spreading to customers or clients
- Educate end users, if they do get a virus dont
make a fuss or make them feel embarrassed, it may be your fault
anyway
- Allow users to use their corporate e-mail account
for personal use, this is more secure than Hotmail blowing a hole
in your defences
- Finally visit the Microsoft web site and download
the latest security fixes for Internet Explorer in particular, the
latest patches for Blaster
