Troj/Loader-S is not that easy to detect
Troj/Loader-S is classified as a dangerous Trojan horse which can mess up an infected PC. Usually, you may get infected by this Trojan horse via free downloads. Other viruses or malware also may drop it into your system. After it got to your PC, it may inject itself to your registry entries and delete your files randomly. Your anti-virus program and firewall may be attacked. So your anti-virus program may not be able to detect it out. You just can sense that your PC moves slower than it should be. You should not take this threat slightly.
