Unlike malicious software, the Trojan won’t show up to let you see it clearly. The only way for ordinary computer users to see it is antivirus program detection. You can’t go to the control panel to uninstall this Trojan. And because the antivirus program is unable to grab it accurately, you may not know what to do.
