What is a computer worm?
A computer worm is a malware which replicates itself without a computer program. Worms seldom affect single machines, they prefer to feed on networks. This doesn't mean your home PC is safe from them.
Why is a worm more dangerous than a virus?
There are several reasons why a computer worm is more problematic than a computer virus:
1. They do not need a host program to run—this means that once the worm has entered your network, it can propagate replication on its own. Not only would it affect the system it's on but also all the systems in the network.
2. The worm creates a path allowing the creator to access and alter information on the infected system. All your passwords, contacts, etc., are in the clutches of the author of the worm. A worm finding its way into an official network, can access all vital data of the company. They can even use your email id to send Spam and other kinds of troublesome information.
3. The author can alter the registry of the infected system(s) thus leading to system failure and arousing the need for data recovery.
Diagnosing a worm infection:
1. Slow computer
2. Slow Internet connection
3. Random re-starting of the system
Steps to take after a worm infection:
1. Use an updated anti-virus or anti-spyware to remove the worm.
2. Worms can be distributed via emails so ensure that all systems in a network have a firewall 3. which protects it against a worm attack.
The most dangerous part of a worm attack is the fact that the registry of your system could be damaged intentionally. This would leave your data inaccessible. If you have a back-up, you can easily restore the information onto a new computer. If that option is inapplicable, contact a data recovery service. They can reclaim all your lost information for you.
