It is quite difficult sometimes to remove a Trojan virus from your computer, even if you're using good anti-virus software. I actually had this problem when the software I used could not remove the Trojan virus. After several tries, I decided to manually delete the virus.
1. Locate the name of the Trojan virus in the scanning report after you run the software.
2. Copy the name of the file, that contains the virus
3. Perform a Windows search by clicking Start, then Search
4. Finally, click the link marked "all files and folders" and paste the name of the Trojan virus in the search box. Find it and delete.
