 (2 plug-ins)

In fact, this is the ultimate cause of the problem because the malware is installed, but it’s located in a slightly different location. Some Antivirus software (the user has Dr. Antivirus) doesn’t even scan the file in this path, and it happens to be exactly where the Antivirus is installed.
In fact, this is the final reason for the user’s problem, because the malicious plug-in is installed, but the location of the plug-in is very special, which makes it impossible for the user to find, and even some anti-virus software (user has installed Dr. antivirus) does not scan the files in this path, just where the malicious plug-in is installed.
