Computer viruses are programs designed to infect one computer, reproduce and spread to additional systems, according to Microsoft. Viruses are designed to perform different tasks that harm your computer. As a result, if your Dell laptop shows symptoms of a virus—crashes, slow performance or unusual error messages, for example—you should remove the virus as soon as possible to prevent damage or data loss. Dell laptops come with a trial version of McAfee Security Center installed. To get rid of a virus on a Dell laptop, you can run anti-virus tools, which identify, locate, quarantine and remove viruses and other malicious software.
McAfee Security Center Virus Scan
Open your Dell laptop's anti-virus program. When you bought your laptop, you received anti-virus trial software. Click "Start" and point to "All Programs" and select the software—McAfee Security Center, for example—to open the software. If your trial expired, connect to the Internet to complete the purchase when prompted.
Click "VirusScan Console." If a window appears asking if you would like to use the program, select "Yes."
Right click "Full Scan" then left click "Start." It can take several minutes to several hours to complete the scan. When the scan finishes, close the scan software and restart your computer. Scan the computer again to make sure the system is clean.
