What’s the best virus protection?

Yes, you probably guessed it, the simple answer is  – it’s you.

If you practice safe and smart computing then it greatly reduces the chances of your PC being infected with something malicious and harmful. Here are some basic tips;

  1. Don’t open unexpected attachments: Beware of unexpected email attachments even if you know the sender. Their PC may have become infected and it could be auto-generating malicious emails that are sent out to people in their contact list
  2. Beware of links: It’s easy to spoof URLs within emails so if you’re suspicious then don’t click the link. Be especially careful if you receive a notice that appears to come from your bank or from PayPal as it may be a phishing scam
  3. Keep Your Mail Client, Web Browser, and Operating System up-to-date: These updates will patch potential security holes that may be exploited by malware
  4. Avoid the dark side. Sites that provide illegal downloads or triple-X rated content are popular places to set digital traps, so avoid
  5. Close pop-ups with care: Use Alt-F4 to close unwanted pop-up ads rather than clicking the X button as X may be part of the ad thereby taking you somewhere that you don’t want to go
  6. Use anti-virus software: This will provide protection against many known infections and prevent them from being passed on to others without your knowledge

Spam

Spam, spam, spam, email and spam

Whenever you include an email address on a web page it may be vulnerable to spam attack.  This is because spammers use automated search programs (or spam spiders) to search for email addresses on the web to which they can then send their spam.

In CMS Made Simple, there’s a handy trick to encode an email address so that it displays and functions normally but cannot easily be found by an automated scanning system. This technique is sometimes referred to as ’email obfuscation.’

Instead of directly adding the email link in html as <a href=”mailto:me@example.com“>, you can use the Smarty {mailto} tag to encode the email address e.g.

  {mailto address="me@example.com" encode="javascript"}

The {mailto} tag will automatically encode the email address into Javascript, hex or other format, concealing it from spam harvesters. The above tag is encoded to:

<script>
    eval(unescape('%64%6f% ... snipped ...%61%3e%27%29%3b'))
</script>

The {mailto} tag supports parameters that allow you to specify the encoding method, text to display for the email link, email subject line, additional recipients and more. See more details on the Smarty {mailto} function at the Smarty website.
