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?
- A. Enable the quarantine feature on both antivirus software programs.
- B. Launch Windows Update, and then download and install OS updates
- C. Activate real-time protection on both antivirus software programs
- D. Uninstall one antivirus software program and install a different one.

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.

During an enterprise rollout of a new application, a technician needs to validate compliance with an application's EULA while also reducing the number of licenses to manage. Which of the following licenses would best accomplish this goal?
- A. Personal use license
- B. Open-source license
