To permanently remove an ad banner, sometimes you need to use several methods at once. Unfortunately, even this approach does not guarantee that the banner will not appear again.
Necessary
access to the Internet
Instructions
Step 1
First, restart your computer and hold down the F8 key. In the Advanced Boot Options menu, highlight the Windows Safe Mode item. Press the Enter key. Wait for the operating system safe mode to start. Most likely, the banner will not appear on launch.
Step 2
Now connect to the internet and visit the site https://www.freedrweb.com/cureit. Download Dr. Web CureIt, a utility for fast computer scanning. Restart your computer normally. Run the downloaded application. Wait for the computer scan process to complete. Delete all files suggested by the program
Step 3
If the utility did not cope with the task, then visit the following resources:
support.kaspersky.com/viruses/deblocker, https://www.drweb.com/unlocker/index/,
Fill in the fields required to define the type of ad banner. Click the Find Code or Get Code buttons.
Step 4
Enter the combinations suggested by the resources in the ransomware banner field. After entering the correct password, the banner window should close.
Step 5
If you cannot find a suitable password, then restart your computer again and start it in safe mode. Open the local drive that contains the operating system. Go to the Windows folder. Now open the system32 directory. Open the properties of the folder and specify the sorting of files "by type".
Step 6
Find all dll files. Remove those whose names contain the combination of letters lib. If you have performed the delete operation "to the trash", then empty it. Restart your computer and start Windows normally. Make sure there is no banner. Perform a full scan of the operating system with your antivirus program.
