Backdoor.Salgorea is a backdoor Trojan that opens a back door on the infected computer. Backdoor.Salgorea may spread through spam email containing a malevolent .hta file. When Backdoor.Salgorea is run, it copies itself as the potentially malicious files on the compromised PC. Backdoor.Salgorea creates a partially modified copy of itself to the temporary folder and executes this copy with parameter '--help'. Backdoor.Salgorea also creates the clean file and runs it. Backdoor.Salgorea then creates the schedule task files in order to execute the file 'sidebar.exe' daily. Backdoor.Salgorea creates the registry entry so that it can run every time you start Windows.
