Trojan.Botime is a Trojan that downloads other malware threats on to the infected computer. When Trojan.Botime is executed, it creates a copy of itself as the malicious file to the certain location. Trojan.Botime then affects the file by patching the export function called 'ImeInquire'. Trojan.Botime creates the registry entries so that it can run automatically whenever the keyboard is used. Trojan.Botime also creates other registry entries. Trojan.Botime then modifies the registry entries to change Internet Explorer settings. Trojan.Botime also modifies other registry entries. Trojan.Botime inserts itself into the process called 'svchost.exe' and executes. Trojan.Botime then decrypts the payload, which is stored in the registry entry, and executes it.
