How to remove trojanclicker-win32-doplik

Hi! Sorry to hear that you have troubles with this situation, restart Windows into Safe Mode with Networking using Troubleshoot > Advanced options > Startup Settings > Restart, then choose Safe Mode with Networking. Safe Mode starts Windows with only a limited set of drivers and services, which can prevent some malware-related startup components from loading. Once there, delete the exact file shown in Protection history if it is in a temporary folder, Downloads folder, browser cache, or an obviously suspicious installer location. Then open Settings > Apps > Startup or Task Manager > Startup apps and disable anything unknown or suspicious, since Windows allows startup apps to be managed from both places.

Also check whether the malware changed browser or network-related settings. Malware/adware can modify the Hosts file to redirect users to malicious websites, so if security websites are being blocked, that is worth checking too. The Hosts file is normally located in %systemroot%\system32\drivers\etc. After that, remove unknown browser extensions, clear browser data, and reset the affected browser settings if the infection started after installing a free program, extension, crack, downloader, or “update” pop-up.

Trojans like TrojanClicker:Win32/Doplik can block security tools and reinstall themselves, so use multiple Microsoft tools and offline scanning to remove them.

1. Run Microsoft Defender Offline This helps remove malware that interferes with normal Windows operation.
2. Save all open work.
3. Select Start > Settings > Update & Security > Windows Security > Virus & threat protection.
4. Under Current threats, select Scan options.
5. Select Windows Defender Offline scan and then Scan now.
6. The PC will restart and run an offline scan; follow any prompts to remove threats.

If the malware keeps coming back after normal restarts, repeat this offline scan until no threats are reported.

2. Use Microsoft Safety Scanner If Defender is having trouble cleaning everything, run Microsoft Safety Scanner as an additional on-demand tool.
3. On a clean PC if necessary, download the correct version of Microsoft Safety Scanner (32-bit or 64-bit) from the Microsoft page and copy it to the infected PC if the malware is blocking downloads.
4. Run the downloaded file (msert.exe).
5. Choose a Full scan and start the scan.
6. When finished, review the results on screen; for detailed results, open the log at %SYSTEMROOT%\debug\msert.log.
7. If needed, download a fresh copy and scan again (the tool expires after 10 days).
8. Ensure Defender is fully updated and cloud protection is on After cleaning, make sure Microsoft Defender Antivirus can detect the latest threats.
9. Go to Start > Settings > Update & Security > Windows Security > Virus & threat protection.
10. Select Manage settings under Virus & threat protection settings.
11. Turn Cloud-delivered protection and Automatic sample submission On.
12. Back in Virus & threat protection, under Virus & threat protection updates, select Check for updates, then under Threat definitions, select Check for updates.
13. If malware is still detected or keeps returning

• Run another Windows Defender Offline scan to catch hidden or persistent components.
• If suspicious files are still not detected or removed, submit them to Microsoft for analysis using the official file submission page.

5. General protection and prevention

• Keep Windows updated using Windows Update to get the latest security fixes.
• Use Microsoft Defender Antivirus for real-time protection.
• Avoid downloading software from untrusted or “shady” sites, as trojans often masquerade as legitimate apps.
• Use a modern browser such as Microsoft Edge with Microsoft Defender SmartScreen enabled to block malicious websites.

If, after multiple offline and Safety Scanner scans, the system remains unstable or reinfected, consider backing up important personal files and performing a Windows reset while keeping files, or a full reinstall if necessary.
