Can you open the recycle bin, Uvah? One reason you can't empty the recycle bin is that some file in there is in use.
If you wish to empty the recycle bin (and you've run a Malwarebytes scan and there's no virus found), do the following:
1. Open an elevated Command Prompt, click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
2. Type the following command: rd /s /q C:\$Recycle.bin and press ENTER.
This clears out the $Recycle.bin folder for the C:\ drive. You may have to do this for each hard disk partition in your system. Change C to their letter.
3. Type exit to close the Command Prompt window.
