Questions and Answers
How are viruses spread?
Viruses are spread in many ways including infected discs, network connections, and downloaded programs. In addition, most new viruses replicate by sending themselves via email to people in your address book. An even more recent devolpment is infections from mearly browsing infected websites.
What is a trojan?
A trojan horse is a program that does something undocumented which the programmer intended, but that the user would not approve of if he knew about it. Many trojans appear as innocent games sent around the internet via email. Many trojans allow unknown remote control of your computer.
How can I protect myself?
Email virus scanning, and anti-virus programs are the best way to protect against infection but not everyone uses them. New viruses are continually released. NTS Communications offers state of the art email scanning, but you should also have anti-virus software on your PC.
What is a Virus?
A parasitic program written to enter a system without permission or user knowledge. Viruses attach to files and replicate, thus continuing to spread. Some viruses do little but replicate, others can cause serious damage. A virus should never be assumed harmless and left on a system
What is a DAT?
All virus programs reference a table of known virus signatures to determine if a given file or system is infected. These tables must be updated on a regular basis to reflect new viruses. These update files are commonly refered to as DATs. Our DATs are updated every hour.
I use a VPN. Can I infect my office?
Yes. Recent virus outbreaks at large firms including Microsoft prove this is possible. Home machines connected to the office network via VPN passed viruses to the corporate network. For this reason, make sure your home virus DATs are updated. Our DATs are updated every hour.
