Norton Internet Security is a good software solution.
It's got anti-virus + firewall.
If you're using Outlook or Outlook Distress, you may be safer switching to view emails in text mode only.
Important things to know about Norton
1) Norton's privacy settings are not anti-hotlink/.htaccess friendly. After installation you may find that images are blocked - the only way to unblock is to switch off the Privacy totally.
2) Norton includes a sneaky Ad blocker which removes some banners, depending on the size of the banner and what html is included around the banner. AdSense links will also become unclickable.
3) Norton adds unwanted Javascript into the source code of a page being viewed.
The sad thing is that these are factory settings and surfers generally have no idea about them.
