The first thing you should do to prevent your computer from becoming infected is to locate and remove any virus-infected files. We recommend that anyone who accesses the Internet should install an anti-virus program on their computer (i.e. McAfee, Norton & Pc-cillin). There is also a free online virus checking service available from Panda Software. Once you have installed an anti-virus program and have it running on your computer, the chances of receiving an undetected virus-infected file is much reduced.
You must also follow the anti-virus program manufacturer’s instructions on how to update the virus definition files. The virus definition files are the data files that the anti-virus program needs in order to stay up to date with the latest viruses out there. Outdated virus definition files cannot recognize new viruses.
