Question 536 - 220-1102 discussion

The most likely cause of the user's laptop issues is that it has been infected by some type of malware or ransomware.Malware and ransomware are malicious software that can harm, exploit, or disrupt devices or networks12.They can cause symptoms such as slow performance, browser redirects, pop-up windows, data encryption, or ransom demands12.Therefore, the first step a technician should take to resolve the issue is to scan the laptop for malware and ransomware using a reliable and updated anti-malware tool34. This can help identify and remove any malicious software that may be present on the laptop. Scanning for malware and ransomware is more effective and urgent than the other options because:

Performing a system restore may not remove the malware or ransomware, as some of them can persist or hide in the system files or backup copies34.Moreover, a system restore may result in data loss or corruption, as it restores the system to a previous state and deletes any changes made after that point5.

Checking the network utilization may not help diagnose or fix the problem, as the malware or ransomware may not be using the network at all, or may be using it in a stealthy or encrypted manner34. Furthermore, checking the network utilization does not address the root cause of the issue, which is the presence of malicious software on the laptop.

Updating the antivirus software may not be sufficient to detect or remove the malware or ransomware, as some of them may evade or disable the antivirus software, or may be too new or unknown for the antivirus software to recognize34. Additionally, updating the antivirus software does not guarantee that the laptop will be scanned for malware or ransomware, as the user may need to initiate or schedule the scan manually.
