Computer Viruses - What are They? What to do about them?
by Kelley Kilanski
A computer virus is similar to a biological virus in that it is spread from one computer to another in a similar way that viruses spread from one person to another. Additionally, a computer virus cannot spread until it is executed. In order to be executed, a computer virus rides on top of other programs or documents, and then the harmful effects begin.
Once you have a computer virus has become 'alive' and started to infect your computer a whole host of problems can arise. Most of the problems caused by viruses are not entirely damaging to your computer, while some can be destructive in that they can destroy damage. Most of the negative effect of viruses comes in the form of the out of control reproduction, which can take up computer space.
Computer viruses are also extended to worms spread over the internet, which act in a similar fashion, but are more harmful and malicious in intent.The best solution is to get good software that will scan your computer for any Spyware, Adware and Viruses you might already have installed as well as eliminate it and protect you from further invasions.
One other thing to note is that while most viruses are targeted toward Windows Operating Systems, all operating systems, including Mac OS and Linux can be infected.
Your best protection is Anti-Virus Software that continually updates and to be careful about what you download off the internet. You only want to download from services or websites that you know to be safe.

Symantec, McAfee, and AOL add backup and antiphishing tools to suites.
by Narasu Rebbapragada
A new generation of security software embodying a holistic vision of PC health is right around the corner. Besides offering updated security features, new software from AOL, McAfee, Microsoft, and Symantec promises backup services and PC tuning utilities, with a different, yearly service type of pricing.
Microsoft kicked off the new trend at the end of May with its launch of Windows Live OneCare, which combines antivirus, antispyware, and firewall tools with Windows' defragging and cleanup utilities in one easy-to-use interface. OneCare also backs up data to CDs, DVDs, and external hard drives--though not to network drives or online storage.
Not to be outdone, established security companies McAfee and Symantec are assembling competing offerings; even AOL is throwing its hat into the ring. McAfee's new all-in-one package, Total Protection, came out in public beta in June, with a final version scheduled for late summer. Symantec's entry, Norton 360, should appear by March 2007; and on July 13, AOL unveiled a members-only beta of its Total Care suite. AOL will make the final version of Total Care available to nonsubscribers, though the company is not commenting on pricing; no final release date has yet been announced.
In addition to firewall, antispyware, and antivirus protection (AOL uses McAfee's engine for antivirus scanning), all three new products will add varying types of antiphishing features. OneCare lacks these defenses, probably because they're built into the new Internet Explorer 7. Like IE 7, AOL's limited feature blocks known phishing Web sites; McAfee's and Symantec's more sophisticated offerings can also analyze other Web sites and rate the sites' safety.
AOL, McAfee, and Symantec are also trying to outdo OneCare by supplementing their backup services with online storage. McAfee's Total Protection beta currently comes with 1GB of online storage. Symantec is still firming up pricing and features for its online backup service, and AOL says that it will be offering online backups, but not in time for the July 13 beta.
Priced at $50 per year for three PCs, OneCare is less expensive than traditional security suites, which tend to run $50 and up for a single PC (plus a yearly antivirus subscription fee). The cost covers all software updates, too; most traditional products do not. Clearly, consumers have found Microsoft's package enticing: According to NPD Group, a market research firm, OneCare ranked among the top eight pieces of software sold in the United States during its first two weeks on retail shelves.
Chris Swenson, director of software industry analysis for NPD Group, expects similar pricing for Total Protection and Norton 360, though neither McAfee nor Symantec has specified prices. He also anticipates improved customer service as the companies compete. Microsoft offers free phone-based tech support, compared to McAfee's $3-per-minute and Symantec's $30-per-incident phone support. Symantec is building real-time chat into its products, and AOL says its pricing will vary depending on the level of support it provides.
Microsoft's giant leap into the security software market caused quite a shake-up--and according to Swenson, that's a positive thing: "Consumers will benefit in the end."
