Bad Experience with a Key Logger Software
During my WoW, World of Warcraft, days there was a constant arrays of insecurities due to key logger software and programs that might be infected in the computers. A key logger can be used for malicious intent or usage. The reason why gamers and PC users fear that a key logger software is installed in their computer is because with a malicious key logger installed into the computer, private information such as credit card passwords, security passwords, and other private information can be taken from the computer and transmitted to another server or computer. A real life example of this occurring is when WoW accounts could have been sold for quite some money, or when items in the game was worth to a certain substantial amount of money. A gamer friend of mine downloaded to what he believe a virus/key logger free modification to up his WoW gaming experience, but after a few days he downloaded this modification. He could not log onto his account due to a password change. The process in which it takes to change someones password or to reset the password takes a long time, by the time the gamer friend receive the reset password the account's items and currency has been taken and transfer to a different account. It can be devastating when losing items and currency in the game because it takes so much time to gain them in the first place.
