When your children use your computer connecting to the Internet is risky. Studies show that teenagers often download games that may be infected with computer viruses and malware. They may know a lot about technology, but they are not always careful.
Kids posting on Facebook may mention that the family is on vacation, which could lead to burglary. They may post embarrassing family information that relatives would not like employers to see.
Families with several computers on a wireless network face other problems. Modems wirelessly connect computers to the Internet. Passwords may not be secure. For example, hackers know the default password of many brands of modems. Make sure your modem is password protected. This keeps others from using your computer without your knowing about it.
Experts say you should keep your antivirus software automatically up to date.
If you think your computer is infected, disconnect it and get help.
