A lot of people in the antivirus industry were afraid that Microsoft was going to kill the antivirus market. This hasn't happened yet, despite the fact that Microsoft is performing OK in independent antivirus tests.
But Microsoft's is but one free antivirus product; there are many other brands as well. What are the free antivirus products and can we trust them?
Initially, free software was always associated with Open Source Software: tools made by smart geeks; not very pretty, but working well.
Instructions
1. Choose an antivirus program. Popular programs available for purchase on disc include McNorton and McAfee. Online programs include Trend Micro and AVG. These are are available from their websites (see Resources) as free or charged editions.
2. Check for viruses. If your computer is already infected by viruses it may block the installation of the software. Use an online virus scan, such as that from Trend Micro (see Resources), to check for the existence of such viruses before you begin installation.
3. Remove any other antivirus software from your computer's hard drive. To do this, enter the Control Panel menu and open the "Add/remove programs" window. Scroll through the list and delete any remnants of previous antivirus software.
4. Close all programs. Ensure programs are closed and not just minimized. If there are icons or items listed on the taskbar at the bottom of the computer, close them by right-clicking once on the item and then left-clicking once on the "Close" option on the drop-down menu that appears.
5. Insert the software disc or run the downloaded file for your antivirus program. Follow the onscreen prompts to install the software including selecting the file destination and agreeing with the licensing requirements.
