Possible system changes
If the Trojan was run and a hacker executed files on the computer, it may be difficult to determine exactly what was done, even after you remove the Trojan. If you are familiar with your operating system and how to use system-repair or system-checking tools, we suggest that you fully check the system for any of these modifications and undo them. Otherwise, consider reinstalling Windows.
