Our Server-Side Anti-Virus Software comes from the industry leaders and is charged to us on a 'per domain' basis.

You may have just one, or a thousand domains - some of which may be empty or contain just documents and pictures which don't need virus protection.  Others will have critical applications and email and should be protected.
The point is - It's not practical to estimate the cost for unknown quantities of anti-virus packs that could be unnecessary.

Consequently, Anti-Virus is a chargeable add-on

Email Anti-Spam Filters - Protecting against a different plague, are included with standard packs at no extra charge.

Why is 'Server-Side' Anti-Virus important ?
Protecting home & business computers from viruses is essential. 
Your Web site is no different.

Viruses can devastate entire networks, steal sensitive data and in many cases destroy data.  Repairs can be very expensive, and in some cases - simply not possible..

Once installed, the software updates automatically every few hours.
Each virus scanner you buy will totally protect one specified domain, no matter what applications and email facilities you activate on that domain. Don't wait until it's too late - activate Virus Scanning on your domains now!
