We all need protection from all malicious programs and attacks from the internet. Protect your desktops ahead of the threat with multi-layered protection starting at the starting point of communication; Your internet connection.

In any case, constant updating of antivirus and anti-spyware programs is crucial. The following best practices are recommended to protect against spyware and adware:

• Be vigilant-and selective-about what programs you download, install, and store on your computer. Read all end-user license agreements carefully to be sure you are not agreeing to install unwanted software.
• Be equally vigilant about what Web sites you visit. Free gaming, music download, and pornography sites are notorious distributors of spyware and adware.
• Install and regularly run Internet security software that includes antivirus and anti-spyware components.
• Do not disable enterprise antivirus, anti-spyware, or firewall protection.
• Seek technical support if you notice a general system slowdown or unusual presence of pop-up ads on your desktop, or within your browser.
• Keep all Internet security patches up to date.
• Check with your Internet Service Provider (ISP) to see what level of protection is provided against spyware and adware.
