1: What is Malware and How Do I Know if My Computer is Infected?

Malware has become the name for any type of malicious software such as spyware, adware, or viruses that harm your computer's performance or security. Most malware infections stem from Internet activity which include downloading files or even 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.

  • Browser Redirects, Popups, Homepage Changes: The browser may suddenly redirect to an unknown website, or a previously set homepage may change without warning or input.
  • Slow Computer Response: The computer may seem to "lock up" or run slow during regular use. It is also not uncommon to experience delays in the operating system loading to the desktop.
  • Processor Utilization at 100% in Task Manager: The processor seems to be working overtime and/or slowly. To check the processor utilization or the Kernel Memory status, press the CTRL ALT + DEL keys simultaneously. Then click the Performance tab. Processor utilization is indicated by the CPU Usage gauge.
  • Virtual Memory Low Message: This message keeps appearing no matter what changes are made to resolve the issue.

2: Determine if Security Software is on Your Dell Computer and Get Support

Determine if you have security software that is already installed on your computer. If so, refer to your vendor for information about removal of malware. 

To determine if you have security software, check the System Tray in the bottom-right corner of your screen for a security icon. McAfee icons typically are red with a large letter "M" in the center of the icon.

NOTE: If you do not have or do not wish to purchase any Internet security software, Windows 10 includes comprehensive security software. Visit the Windows Security Hub to preview and get support.
