1) Use antivirus software and keep it up-to-date. You should check for new definition updates
daily. Most antivirus software can be configured to do this automatically. 2) Install security
patches. Vulnerabilities in software are constantly being discovered and they don't discriminate
by vendor or platform. It's not simply a matter of updating Windows; at least monthly, check for
and apply updates for all software you use. 3) Use a firewall. No Internet connection is safe
without one. Firewalls are necessary even if you have a dial-up Internet connection -- it takes
only minutes for a a non-firewalled computer to be infected. 4) Secure your browser. Many
labor under the dangerous misconception that only Internet Explorer is a problem. It's not the
browser you need to be concerned about. Nor is it a matter of simply avoiding certain 'types' of
sites. Known, legitimate websites are frequently being compromised and implanted with
malicious javascript that foists malware onto visitors' computers. To ensure optimum browsing
safety, the best tip is to disable javascript for all but the most essential of sites -- such as your
banking or regular ecommerce sites. Not only will you enjoy safer browsing, you'll be able to
eliminate unwanted pop-ups as well. 5) Take control of your email. Avoid opening email
attachments received unexpectedly -- no matter who appears to have sent it. Remember that most
worms and trojan-laden spam try to spoof the sender's name. And make sure your email client
isn't leaving you open to infection. Reading email in plain text offers important security benefits
that more than offset the loss of pretty colored fonts. 6) Treat IM suspiciously. Instant
Messaging is a frequent target of worms and trojans. Treat it just as you would email. 7) Avoid
P2P and distributed filesharing. Torrent, Kazaa, Gnutella, Morpheus and at least a dozen other
filesharing networks exist. Most are free. And all are rife with trojans, viruses, worms, adware,
spyware, and every other form of malicious code imaginable. There's no such thing as safe
anonymous filesharing. Avoid it like the plague. 8) Keep abreast of Internet scams. Criminals
think of clever ways to separate you from your hard earned cash. Don't get fooled by emails
telling sad stories, or making unsolicited job offers, or promising lotto winnings. Likewise,
beware of email masquerading as a security concern from your bank or other eCommerce site. 9)
Don't fall victim to virus hoaxes. Dire-sounding email spreading fear, uncertainty and doubt
about non-existent threats serve only to spread needless alarm and may even cause you to delete
perfectly legitimate files in response.
accidentIn general, an unplanned, unexpected, and undesigned (not purposefully
caused) event which occurs suddenly and causes (1) injury or loss, (2) a decrease in value of the
resources, or (3) an increase in liabilities. As a technical term 'accident' does not have a clearly
defined legal meaning. In insurance terminology, an accident is the events which is not
deliberately caused, and which is not inevitable. For example, if a driver (who is covered under
personal automobile insurance for injury and losses due to negligence) willfully drives the
vehicle into a tree, the resulting injury or loss is not insured. Similarly, insurance policies do not
compensate for obsolescence or wear and tear because their occurrence is inevitable in normal
course of things. See also incident.

Causes of accidents

An accident often has more than one cause. Accidents can be prevented by removing their
Basically there are two causes of accidents:

1. Unsafe acts and procedures, eg:

      lack of training
      lack of suitable equipment
      inappropriate use of equipment.
      2. Unsafe conditions, eg:

      confined space
      lack of protective equipment
      too few staff/too many staff.
