If you have ever been attacked by your girlfriend for having pornographic sites in the history tab of your computer or bookmarked in your favorites folder, reprieve is in sight. You can blame it on porn bookmarks that have been secretly placed on your computer, which will allow you to save yourself from losing yet another battle.

Computer forensic specialists claim that web site lists, including everything from ad bookmarks to pornographic websites, can be placed into computers by malicious software. One such program, CoolWebSearch, also called CWS or CoolWWWSearch, has been injecting porn bookmarks since 2003. Some reports have estimated that 5 million sites are infected with it and that over 60 strains might exist.

A substitute teacher in Norwich, Connecticut was arrested, criminally prosecuted and convicted on four counts of risk of injury to a minor and impairing the morals of a child after her computer, which had been used by students, began displaying pornographic ads. Controversy over the school's spyware and firewall protection caused a New London superior court judge to throw out the conviction and the teacher was granted a new trial. If you don't want to end up in the slammer, rest easy because there are ways to combat the malware. Most spyware programs and network firewalls, if updated regularly, will protect you from malevolent bookmarking from unwanted and untrustworthy sites.

Not a victim, but a willing voyeur? This story might be even more pertinent to you. Just play the victim card. Though it is relatively easy for a forensic specialist to determine whether a person visited a pornographic website or if the bookmarks were placed by spyware, it's not so easy for the average person to recognize. A word to the wise: You might be able to talk your way out of a favorites bookmark, but you'll never clear your name if she finds the proof in your credit card statements.
