Countermeasures:

Reducing Your Chances of Infection:

To make yourself less of a target for virus infection, take the following steps:

1. Restrict your file downloading to known or secure sources. The surest way to catch a virus is to download an unknown file from an unknown site; try not to put yourself at risk like this unless you absolutely have to.
   

   
    

2. Don't open any e-mail attachments you weren't expecting. The majority of viruses today arrive in your mailbox as attachments to e-mail messages; resist the temptation to open or view every file attachment you receive.
   

   
    

3. Use an up-to-date anti-virus program or service. Antivirus programs work; they scan the files on your computer (as well as new files you download and e-mail messages you receive) and check for any previously identified viruses. They're a good first line of defense, as long as you keep the programs up-to-date with information about the very latest viruses— and most antivirus programs make it easy to download updates.
   

   
    

4. Enable macro virus protection in all your applications. Most current Microsoft applications include special features that keep the program from running unknown macros—and thus prevent your system from being infected by macro viruses.
   

1. Create backup copies of all your important data. If worse comes to worst and your entire system is infected, you may need to revert to no infected versions of your most critical files. You can't do this unless you plan ahead and back up your important data.
