The internet offers users such a wide variety of information, entertainment, and references, it's become a global main source for research, computer games, communication, and even shopping. However, as internet traffic grows, so does the risk of contracting a computer virus.

One major source of internet entertainment is the availability of free games. Fans of software-based computer games are discovering the many websites that offer online games similar to their favorite computer games. Much of these online games are free games, and do not require a subscription - and this is where trouble can start.

Reputable sites providing big-name online games such as World of Warcraft or Guild Wars rarely have problems with computer viruses or spyware. Most online games that contain spyware or a computer virus usually come from free game sites that don't require a player to subscribe. The types of online games most notorious for transmitting computer viruses are card games, such as poker, and online casinos. Many of these gambling sites are run by unknown companies and offer free game trials to attract new players.

Most internet users know that being online in itself carries a risk, and they know better than to trust a seedy-looking website that offers free games - or free anything. But there are plenty of reputable sites that provide users an opportunity to play free games without the risk of contracting a computer virus. Many computer viruses are actually disguised as online games; when launched, they infect the user's computer. Some tips on how to avoid picking up a computer virus from online games include:

1. Be sure the free game is from a trusted website. Many large companies, such as Yahoo and MSN, offer free games as part of the site features. These and similar sites are relatively safe free game sources.
2. Steer clear of free games on peer-to-peer (P2P) networks. Computer games shared on P2P networks often contain computer virus or spyware bundles, which can leave your computer open to hackers.
3. Use common sense. Don't download free games from sites that contain a lot of various popups or ads, and don't click on any of the ads. Fiddling too much with posted ads can take you to sites that may try to download computer viruses or spyware into your system.
4. Protect your system from computer viruses by installing and running the latest updated version of a reputable antivirus/anti spyware program. Running an up-to-date firewall and installing a popup blocker will also help you to avoid a computer virus.

The world of online games doesn't have to be a threat. There are plenty of sites that provide users with safe, free games without the risk of computer viruses. As long as you exercise caution and common sense, your gaming should continue uninterrupted by computer viruses. Taking the proper steps to protect your computer will leave you free to play all the online games you like without infecting your system.
