Do not allow unfamiliar people to use your computer. They may try to infect your computer with Trojan horse while you are away. They may do it to steal your Internet account information, credit card information or other valuable data. It takes no longer than one minute to infect your system by a Trojan. The person who is going to infect your computer needs to copy a Trojan to your hard disk and run it. So try not to leave unfamiliar people alone with your computer as it takes too little time to infect your computer.
