(CLOSE) How to repair my unity session after deleting potentially dangerous file with ClamAV?

Question

I performed tonight, a virus scanning with ClamAV by running the software with the supersusers options by mistake, and after removing the detected potential threats, I can not login to my Unity session anymore. Indeed when I enter my password, the system constantly returns to the login page. Other users and invited sessions works normally. I can also use the console by pressing Ctrl + Alt + F1. I tried to perform a unity reset but no positive result

Could you help me fix this problem quickly?

Best regards.

Here is the output of ls -lah

This was a comment left that answered the question, and for easier access to a fix, here it is. NOTE all credit should go to steeldriver!!

Your files that let you login w/unity and enter Ubuntu are owned by root, not your user (In this case romain) Fixing this is simple. On the login screen do CTRL + ALT + F3 And that should bring you to a terminal like program. If it doesnt try CTRL + ALT + F1 Instead. Anyways, once you're at the terminal screen do

ls -lah

And any files that have "root" ownership, Chown them. For example if the file was located at /home/(USER)/example.file you would do

sudo chown -R romain:romain /home/(USER)/example.file

NOT RECCOMENDED, AS VIRUSES TRY TO MANIPULATE /HOME FOLDER FILES But if you want to simply chown all of your /home files at once you can do:

sudo chown -R romain:romain /home/romain/

Then reboot and login!
