    Internet Online Security


  • Buy some "anti-virus" software and install it.
  • Always uninstall any previous anti-virus software, before installing any new anti-virus software.
  • Always ensure you have a "firewall" operational.
  • Regularly run your anti-virus software.
  • If you have "windows" operating system, ensure that your computer is able to recieve updates.

    Internet Online Banking

  • NEVER respond to any emails which appear to be from your bank, which request your passwords
    or other personal information. This is a scam by organised criminals to access your account .
  • Always sign-out when you have finished viewing your online banking account.
  • We advise not to access your account from any computer other than your own.
  • We advise never to login from any email which appears to be from your bank; always login from the trusted URL address, from a trusted search engine.


    • Internet Online Shopping

  • Always look for the closed padlock icon on your browser's status bar and 'https' in the address bar
    before submitting your personal information via a Web site. This usually confirms that you
    are transmitting your information via a secure site.

Web search engines work by storing information about many web pages, which they retrieve from the WWW itself. These pages are retrieved by a Web crawler (sometimes also known as a spider) — an automated Web browser which follows every link it sees. Exclusions can be made by the use of robots.txt. The contents of each page are then analyzed to determine how it should be indexed (for example, words are extracted from the titles, headings, or special fields called meta tags). Data about web pages are stored in an index database for use in later queries. Some search engines, such as Google, store all or part of the source page (referred to as a cache) as well as information about the web pages, whereas others, such as AltaVista, store every word of every page they find. This cached page always holds the actual search text since it is the one that was actually indexed, so it can be very useful when the content of the current page has been updated and the search terms are no longer in it. This problem might be considered to be a mild form of linkrot, and Google's handling of it increases usability by satisfying user expectations that the search terms will be on the returned webpage. This satisfies the principle of least astonishment since the user normally expects the search terms to be on the returned pages. Increased search relevance makes these cached pages very useful, even beyond the fact that they may contain data that may no longer be available elsewhere. When a user enters a query into a search engine (typically by using key words), the engine examines its index and provides a listing of best-matching web pages according to its criteria, usually with a short summary containing the document's title and sometimes parts of the text. Most search engines support the use of the boolean operators AND, OR and NOT to further specify the search query. Some search engines provide an advanced feature called proximity search which allows users to define the distance between keywords. The usefulness of a search engine depends on the relevance of the result set it gives back. While there may be millions of webpages that include a particular word or phrase, some pages may be more relevant, popular, or authoritative than others. Most search engines employ methods to rank the results to provide the "best" results first. How a search engine decides which pages are the best matches, and what order the results should be shown in, varies widely from one engine to another. The methods also change over time as Internet usage changes and new techniques evolve. Most Web search engines are commercial ventures supported by advertising revenue and, as a result, some employ the practice of allowing advertisers to pay money to have their listings ranked higher in search results. Those search engines which do not accept money for their search engine results make money by running search related ads alongside the regular search engine results. The search engines make money every time someone clicks on one of these ads.
