The Malagent trojan has a modular architecture and can be modified to serve several purposes. The Malagent trojan can be adapted to download other malware such as viruses, keyloggers, and worms. Additionally, the Malagent malware can be used by hackers to commit click-fraud and earn pay-per-click revenue. Security experts add that another possible application of the Malagent trojan is to give attackers remote access to compromised systems. The Malagent trojan is known to modify the Windows Registry of infected users to download malicious DLL files and corrupt the DNS settings. When users start an online session, their Internet queries are rerouted to one or more websites and services, and users are redirected. Security experts note that the Malagent trojan may place the 'sysocmgr.dll' and the 'mshta.dll' files in the Windows directory to perform its operations. Computer users may encounter the Malagent trojan as an attached file to spam emails and embedded in freeware from suspicious software centers. You might want to install a reputable anti-malware program to upgrade your cyber defenses and purge Malagent binary on your system.
