A user believes there is a virus on a laptop. The user installs additional real-time protection antivirus software but is now experiencing extremely slow performance on the laptop. Which of the following should a technician do to resolve the issue and avoid recurrence?

Question

Accepted Answer

E. Remove the user-installed antivirus software The user installed a second real-time antivirus on top of the existing company-issued one; two real-time AV engines simultaneously intercepting file system calls cause resource contention, mutual interference, and extreme CPU/RAM overhead - removing the user-installed software restores the original protected state without the conflict.

Answer

A. Activate real-time protection on both antivirus software programs Activating real-time protection on both programs would intensify the conflict and make performance worse, not better.

Answer

B. Uninstall one antivirus software program and install a different one Uninstalling one and installing yet another different antivirus would still result in two competing real-time engines and does not resolve the root cause.

Answer

C. Run OS updates Running OS updates does not address the performance issue caused by conflicting antivirus engines and would not resolve the resource contention.

Answer

D. Enable the quarantine feature on both antivirus software programs Enabling quarantine on both programs does not stop either engine from scanning in real time and does nothing to reduce the performance conflict.
