The symptoms described suggest that the malware removal may not have been completely successful, and the computer may still be infected or have some residual damage. The issue with Internet Explorer and accessing certain websites may be caused by residual malware or changes made by the malware to the system settings.
Therefore, the technician should consider the following steps to troubleshoot this issue:
Run a full system scan using a reliable antivirus or antimalware software to detect and remove any remaining malware or related system changes.
Reset Internet Explorer settings to default. To do this, open Internet Explorer, click the gear icon in the top-right corner, and select Internet options. Then click on the Advanced tab and select Reset. This will reset all Internet Explorer settings to their default values.
Check the system for any suspicious or unknown programs or extensions. Malware may install additional software or extensions to intercept web traffic and redirect it to malicious websites. To do this, open the Control Panel and click on Programs and Features or Add/Remove Programs (depending on the version of Windows). Look for any unfamiliar programs or extensions, and uninstall them.
Check for any proxy settings or network configurations that may be causing issues. Malware may change the proxy settings or network configurations to redirect web traffic. To do this, open Internet Explorer, click the gear icon in the top-right corner, and select Internet options. Then click on the Connections tab and select LAN settings. Make sure that the "Automatically detect settings" option is selected, and that no proxy settings are enabled.
Check the hosts file for any malicious entries. The hosts file is a system file that maps domain names to IP addresses. Malware may modify the hosts file to redirect web traffic. To do this, open Notepad as an administrator, and open the hosts file located in C:\Windows\System32\drivers\etc. Look for any suspicious entries and remove them.
In summary, the technician should run a full system scan, reset Internet Explorer settings, check for suspicious programs or extensions, check proxy settings and network configurations, and check the hosts file for any malicious entries to troubleshoot this issue. Option A (Internet Options - Advanced) may be useful for resetting Internet Explorer settings, but it is not the most comprehensive solution for this issue. Options B (System - Remote Settings), C (Folder Options - View Options), and D (Display Settings - Resolution) are not relevant to this issue.
