Virus Protection
Viruses have been a threat to computer systems
since January 1986 when two brothers in Pakistan noticed that you could
put extra code in a disk's boot sector and developed the Brain virus.
The speed that viruses and worms can spread nowadays is phenomenal due
to the prevalence of email and the Internet and all organisations using
computers should take steps to ensure their systems are protected otherwise
they risk losing data or being unable to work for days.
Emmtech can give advice on how best to protect your systems from attack. We are also expert at cleaning viruses from your systems and getting everything working again quickly should you be unfortunate enough to suffer an infection.
We will give you protection against the following and so much more;

A "virus" is a program that replicates itself and affects other programs. Viruses do not always cause damage and may not display symptoms, but they can, and sometimes they can be very destructive.
A "worm" is a computer program that replicates itself. Worms do not infect other programs, but instead, they send themselves to other users through e-mail, IRC and Instant Messaging programs.
A "trojan" is a malicious program that pretends to be a normal program. These programs do something that a user does not expect them to do. They are not considered a virus in the true sense of the word since they do not spread themselves to other users.
A "boot sector virus" places malicious code into the first sector of a floppy or hard disk. When the floppy or hard disk is run, the virus is run and performs certain instructions that gain control of basic functions of a computer, and do damage.
A "Denial of Service "(DOS) is an action that occurs when an infected computer is taken over by someone other than the normal user. The computer is then used to prevent the normal functioning of a system and keeps other users from accessing those systems.
A "macro virus" is written using a macro programming language and then attached to an ordinary document file such as Word or Excel. When the document is run, the virus unloads its damage and copies itself into other documents to continue its spread.
A "VBS virus" is one that is written using Visual Basic Scripting. Because of a security hole in Outlook and Outlook Express, this virus can be run without clicking on an attachment.
