web sites. It is important to learn how to deal with these messages in order to
prevent the computer or personal information from being compromised or misused.
</p><p>
Typically such messages are sent by strangers. However, sometimes this type of
email appears to be from a trusted acquaintance, even though that person did not
really send it. It is possible to include a fake sender email address in emails.
</p><p>
Unwanted (unsolicited) mail tends to fall into one of several categories:
</p><div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem"><p>
Spam (junk) email with offers for unwanted services and products.
</p></li><li class="listitem"><p>
Scam emails asking for help in exchange for money.
</p></li><li class="listitem"><p>
Phishing email, that appears to be from a bank or other online service, asking
for personal and financial details or passwords.
</p></li></ul></div><p>Below are some tips for keeping safe online:</p><div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem"><p>
Never reply to unsolicited mail or click on the links in the mail. Doing so
usually results in more junk email.
</p></li><li class="listitem"><p>
Never click on links in emails that lead to web sites asking for passwords or
similar information. It is possible for the text of the link to show one
address, but clicking on the link actually connects to a different (possibly
dangerous) address. Instead of clicking a potentially misleading link, type the
link address directly into a web browser.
</p></li><li class="listitem"><p>
When visiting a web site that asks for financial information, ensure that it is
secure. <span class="application">Konqueror</span> and
<span class="application">Firefox</span> are two browsers commonly used in <span>Kubuntu</span>.
Both have two areas that indicate if the current page is secure. On secure web
pages, the address bar will have a yellow background and a lock symbol to the
right of the address. The second area is the status bar located at the bottom
right of the browser window. If the page is secure, a lock icon will appear in
this area. Clicking on either of the lock symbols will produce a dialog that
explains the type of licensing and security for the page.
</p></li><li class="listitem"><p>
Only download and run software from trusted sources. By default, software can
only be downloaded directly from <span>Ubuntu</span>.
