How to Install Any Antivirus

Antivirus programs scan your computer for viruses, eradicate or recover any infected files that it finds and can even actively monitor your Internet activities to prevent infection. Installing antivirus software on your computer is crucial, since most systems do not come with this type of program by default. Once downloaded and installed, configuring the antivirus software to check for updates automatically and schedule automatic scans of your system can help you stay protected and virus-free.

Instructions

Compare antivirus software. Look at the features and benefits of each. Read reviews from authoritative editors from magazines such as "PC World," "Smart Computing" and "PC Magazine." Editors who write for these magazines typically test antivirus software as an unbiased outsider and write about both the good and bad sides of antivirus software. For example, the editors at "PC World" recommended Avira AntiVir, Avast Antivirus and Panda Cloud Antivirus in an August 2009 article. Visit the websites of each antivirus program to view screen shots and descriptions of how the program works. Make a final decision about which antivirus program you want to install.

Navigate to the website of the antivirus program you've chosen. Go to the "Downloads" section of the site if you're obtaining a free antivirus software. Click on the "Purchase" section or "Buy" button if you have chosen licensed software; pay for and complete the transaction. Click the "Download" button or link for the antivirus program. Save the file to your computer desktop or to a computer directory or folder which you can easily remember.

Find the antivirus program file you downloaded on your computer. Double-click the ".exe" file (which is an executable file that will install the antivirus program). Once you double-click the ".exe" file, the installation process will automatically begin. Click "Continue" or "Next" on each screen to complete the installation process. Enter your name and contact details if registration is required. Follow any other on-screen prompts to complete the antivirus program installation. Restart your computer if necessary.
