Basically there are two possible ways to remove Trojan:Win32/Reveton from your PC i.e. either following the manual removal process or by using an automatic removal tool. The manual removal process involves steps like:
Terminating processes from Windows Task Manager related to Trojan:Win32/Reveton execution
Deleting files from command prompt
Deleting invalid entries from Registry Editor window
However if you are not technical sound enough and find all these steps complicated then it is better to go with the alternative option of using Automatic Trojan:Win32/Reveton Removal Tool.
