"I am a small business owner who was introduced to Teknician by way of an informative newsletter I received as an alumni for a self employment program. I turned to Teknician when my computer crashed... Teknician provided me with an affordable system and software programs that have been consistent with my needs.

I highly recommend Teknician for quick response time, sound professional advice and very friendly, efficient service. Thank you Teknician for making life at the computer more stress-free and therefore more enjoyable!"

Computer Worms vs Viruses

A computer worm is a self-replicating computer program. It uses a network to send copies of itself to other computer terminals and it may do so without any user intervention. Unlike a virus, it does not need to attach itself to an existing program. Worms almost always cause harm to the network, if only by consuming bandwidth, whereas viruses almost always corrupt or modify files on a targeted computer.
