FAQs for Integrated Antivirus Support in Virtual Mail Server
Q. What is this all about ?
A. Computer viruses today are a threat to many computer systems. They destroy data as well as enable computer systems
unusable. The Email system is a medium which is commonly used to spread these viruses. With Webvisions' Integrated AV
Support built into your Virtual Mail Server, it provides an extra layer of protection for your email.
Q. Ok, great, we have an AV Scanner on our emails now, does this mean I am 100% safe ?
A. Absolutely not. There's no such thing as 100% security. Basic AV precautions should still be put in place. These
would include installing AV software on your PCs, being careful about what attachements to open etc. Webvisions will
not guarantee that it'll catch every virus, neither will we be responsible if you get infected as a direct result of
assuming this service exist.
Q. Can I do away with my Antivirus tools now that we have this from Webvisions ?
A. Certainly not. This just adds one layer of protection. Viruses spread through many mediums and are new unknown
viruses are generated every day. It is recommended that you would have at least your standard antivirus tools
available on your desktop to protect you against viruses that may attack your system through any means.
Q. Do I need to update any Virus Defination Files on the Virtual Mail Server ?
A. There is NO need to. Webvisions' Virtual Mail Server will automatically update defination files every two hours. You can find
a list of definations at www.ravantivirus.com / www.clamav.net
Q. What happens when the Virtual Mail Server encounters a virus ?
A. If the scanning module is able to identify a MIME attachment to contain a possible virus, it will automatically
reject the mail and send a notice back to the Sender.
Q. Will a notice be sent to the recipient as well if an email is rejected ?
A. At this moment, it will not. However, this and other features are planned for future releases.
Q. I found have a virus that your AV Scanner does not protect, what do I do ?
A. You can choose to update www.clamav.net. Please do not email us new viruses. There are hundreds of
viruses that are released weekly, we do not have resources to update and track new viruses.
Q. Are all Webvisions Virtual Mail Servers installed with this service ?
A. Yes, when completed, all Webvisions Virtual Mail Servers will be installed with this service.
Do Webvisions Virtual Mail Servers protect us against suspicious file attachments sent via email ?
A. Yes. There is always a lag time between a virus starting its spread and an Anti Virus cure. To protect
our networks and our customers, Webvisions has by default blocked all mail attachments with suspicious
double extensions (.e.g .txt.exe) and common file extensions used by viruses (e.g. .pif, .scr, .com). Customers
should pay heed to advice given by AV companies - Zip your files up before sending emails and scanning
them before unzipping to prevent accidental infection.
We also pro-actively ban suspected viruses and spam content (by keyword matching collated from AV databases (like
Symantec's) or Antispam sites (like SpamCop). The list is large and changes every day. If an attachment you have
sent is blocked, you would receive a notice from your email client that says "Email rejected
due to presence of banned content/attachment". If you have any doubts or concerns, please do not hesitate to contact
support@webvisions.com
Q. I noticed that sometimes viruses do slip through, why is that?
A. The can be several reasons for this. One common reason this occurs is
due to the way email is encoded and sent via
various email clients. Not all scanners know how to unpack every
mime type, or type of encoded email so some uncommon ones do get through. With time,
these would be discovered and added to the scanner's fix list. Another reason
could be that a specific antivirus scanner does not have the signature for this
virus or a lag time between an update of the virus signature. This is not a full proof
solution.
Security has to be managed in a totality sense, it does not mean that if you have
antivirus protection, you can get wanton in opening unknown files. Similarly,
if you had a firewall installed, it does not mean you are fully protected against
hackers. Likewise, if you depended on just a single AV scanner on your mail service
and neglect to install AV scanners on your desktop and relied on the former, then you
are running your own risks.
