A user reports a virus is on a PC. The user installs additional real-lime protection antivirus software, and the PC begins performing extremely slow. Which of the following steps should the technician take to resolve the issue?
Correct Answer:
E
Removing the user-installed antivirus software program is the best way to resolve the issue of extremely slow performance caused by installing additional real-time protection antivirus software on a PC. Having more than one antivirus software program running at the same time can cause conflicts, resource consumption and performance degradation. Uninstalling one antivirus software program and installing a different one, activating real-time protection on both antivirus software programs, enabling the quarantine feature on both antivirus software programs and launching Windows Update are not effective ways to resolve the issue.
