Nov 28,  · There are measures you can take to protect yourself from viruses. According to Klausner, the best way to avoid getting a viral infection is to stay away from sick people, regularly wash your hands (the right way), and avoid touching your nose, mouth, and face. Mar 05,  · Viruses. Viruses are much smaller than cells. In fact, viruses are basically just capsules that contain genetic material. To reproduce, viruses invade cells in your body, hijacking the machinery that makes cells work. Host cells are often eventually destroyed during this process. Viruses are responsible for causing many diseases, including: AIDS.

Keeping antivirus software up to date is critically important for all platforms, even if some of the operating systems, such as Macintosh and Linux, aren't as widely targeted by virus threats. But the key to ensuring that your network remains virus-free is something beyond the deployment of dependable antivirus solutions.

Companies must educate employees about safe computing practices and enforce policies to safeguard the network. Here are some ways to help prevent malicious code from wreaking havoc at your company.

Enforce strict policies. Downloading executables or documents from the Internet is unacceptable, and anything that runs in your organization should be virus-checked and approved first. Unsolicited executables, documents, spreadsheets and such shouldn't be run inside any organization. If you don't know that something is virus-free, assume it isn't. Ideally, employees and staff shouldn't be allowed to have anything they don't actually need.

Block any unwanted file types at the e-mail gateway. Viruses often use file types such as. It's unlikely that your organization will ever need to receive files of these types from the outside. Block any file that has "double extensions" from entering your organization. Some viruses attempt to disguise their true executable nature by using double extensions. Files with names such as love-letter-for-you.

Set a firm policy on hoaxes. Hoax virus warnings and chain letter e-mails can be as disruptive as viruses themselves. Not only do hoaxes spread misinformation and waste staff time and resources, but they can also be embarrassing to organizations whose employees forward them to contacts or customers.

Here's a sample hoax policy:. It doesn't matter if the virus warnings have come from an antivirus vendor or been confirmed by any large computer company or your best friend. All virus warnings should be sent to [insert name] and [insert name] only. It is [insert name]'s job to send all virus warnings, and a virus warning that comes from any other source should be ignored. Change the CMOS bootup sequence so that, rather than booting from drive A: if you leave a floppy in your machine, you boot by default from drive C:.

Should you need to boot from a floppy disk, the CMOS can easily be switched back. Make regular backups of important work and data, and check that the backups were successful. Subscribe to an e-mail alert service that warns you about new, in-the-wild viruses. There are many antivirus vendors and security sources that regularly publish alerts of new virus threats see Computerworld 's antivirus vendor listings.

Keep an eye on Microsoft's security bulletins. These warn of new security loopholes and issues with Microsoft's software. Produce a set of guidelines and policies for safe computing, and distribute them among employees. Make sure that every employee has read and understood them and that they know whom to contact if they have questions.
