This article describes what viruses, spyware and malware are, how to remove a suspected malware infection and ways to protect your system against attack.
Malware has become the name for any type of malicious software such as spyware, adware, or viruses that harms your computer's performance or security. Most malware infections stem from Internet activity which include downloading files or even just browsing Internet sites. Most measures for protecting against malware focus on ways to make Internet browsing more secure. Various symptoms can be associated with malware, so any one (or a combination) of the following symptoms could be good indicators of malware infection.

Determine if you have security software already installed on your computer. If so, refer to your vendor for information on removal of malware. A list of security software vendors' contact information can be found in the Security Software section of the Dell Third-Party Software Contacts page.
One simple way to determine if you have security software is to check the System Tray in the bottom right corner of your screen for a security icon. McAfee icons typically are red in color with a large letter "M" in the center of the icon.
Dell computers can ship with McAfee Security Center or McAfee LiveSafe, either as a 30 day trial version or subscriptions of up to 36 months. Registration of the product is part of the Windows first-time startup process for your PC. Simply accept the End-User License Agreement (EULA) and supply your email address for registration. No further action is required.
The Microsoft Malicious Software Removal Tool accurately detects and removes about 80% of known viruses and spyware from your system.
