Step-by-Step Virus Signature Updating
It is assumed that you already have McAfee VirusScan installed and running on your PC. If you do, you should be able to see the program's characteristic icon on the tray bar (a red square with a large "M" on it). To perform a virus update, you need to do the following:
1. Right-click on the tray icon we just talked about. Having done this you should be able to see a menu, similar to the one in the figure below.
2. Click on the option titled "Updated" (the highlighted one in the previous figure). After you've done this you should be looking at a new window, just like the one in the figure below.
3. To update your McAfee VirusScan program, just click on the first button that is titled "Check Now." Having done that, the program should commence the updating process and you should see a new window just like the one in the figure below.
4. From this point onwards, everything is in auto-pilot; you don't need to do anything else. Once the program is finished, you'll see another window saying that the program has updated successfully and you can return to your work.
Note that in order to minimize the virus infection risk, you should update your anti-virus program regularly (every week or so would be good). If you don't want to do this process manually again (as it is quite tedious and it's easy to forget to do it at regular time intervals), you can set the program to do it on its own. To do that, repeat the first step and on the second step, instead of clicking on the first button, click on the second one instead (titled "Configure"). Then, you should see a new window that looks just like the one in the figure below. The default option works fine, but the second option is good as well. After you are satisfied with your choice, click on the OK button and then on the X button of the previous window (top-right corner), or continue with the updating process (step 2 onwards).
