I have discovered in my Mac Mackeper malware/troyan. I use AVG antivirus I have delete this troyan

Hi Juan,
I understand this must be upsetting. I will help to fix it.
Could you tell me how you identified the Trojan? Did you get any Detection Messages?
Please provide me a screenshot of the Detection message.

To take a screenshot in MAC, please follow the below instructions :
1. To capture the entire screen, press Command-Shift-3. The screen shot will be automatically saved as a PNG file on your desktop with the filename starting with Picture followed by a number, example Picture 1, Picture 2, and so on.
2. To copy the entire screen, press Command-Control-Shift-3. The screen shot will be placed on your clipboard for you to paste into another program like PowerPoint, Word, Photoshop, etc.

How I can delete definitely Mackeeper troyan and malware from my Mac? I use AVG antivirus but after delete from quarantine thus malware begin again to make peoblems!
how to find a solution?
thsnks in advance

For your info, just in case that you are unaware, you can post the screenshot here in your topic. Click on Answer & then click on the Image [mountain symbol] & follow the instructions.

As full path of detection is not fully visible from UI very often, please provide us with the full path. You can copy the path by right clicking on the detection path and pasting it to email or to any text file by standard way.
