If your computer is behaving odd and you cannot see an obvious reason as to why it is happening you have to consider a Trojan infection. Things like Trojan.Mutogen.A, for example, can find a way into your system via bundled downloads, pretending to be a part of a useful program. Sometimes users install Trojan.Mutogen.A themselves, thinking that a shareware program it comes with will be helpful in one way or the other, and it actually can be true, but in the system's background Trojan.Mutogen.A runs malicious processes that will continue to harm your system until you remove the Trojan.
Trojan.Mutogen.A has a lot of aliases and it allows us to see that it is a rather generic Trojan that connects to the Internet in order to communicate with its creator and report about yet another infection. Then it proceeds to slow down your computer and performs various malicious actions that might vary according to what the hacker behind Trojan.Mutogen.A wants it to do. For example, it can collect banking logins and passwords via keylogging and then send it away to the hacker. Also, since quite a few Trojan.Mutogen.A's aliases have dropper features, it would be logical to claim that unless Trojan.Mutogen.A is removed from your system, it downloads and installs additional malware.
It is also hard to detect Trojan.Mutogen.A, because it does not have a direct interface and the process files associated with the Trojan simply hijack legitimate system processes. For example, regedit.exe and winrtm32.exe. regedit.exe is a process file that originally belongs to Registry Editor - and important system tool, while winrtm32.exe belongs to Virus Chaser program. However, if these files are located elsewhere rather than at C:\Windows or C:\Program Files directives, then they really belong to the malware.
Removing Trojan.Mutogen.A might be a bit too hard especially if you are not well-versed in computers. It would be better if you downloaded a reliable security program and removed Trojan.Mutogen.A with it at once. At the same time the program will scan your system for any other malicious programs the Trojans might have brought in.
