1. Use anti-virus software
Generally anti-virus software scans files or a computer’s memory for certain patterns that may indicate the presence of malicious software (i.e., malware). When selecting an anti-virus package, learn about its features so you know what to expect. Once you install an anti-virus package, scan your entire computer periodically.
Keep security software set to automatically receive the latest updates so that it is always current. Never click links within pop-up windows, download “free” software from a pop-up or follow email links that offer anti-spyware software.
