But at this point we don’t have enough information about it due to its novelty.

A very common usage for the Mscorsvw.exe Virus is aiding other malicious threats in entering the infected machine. Hence, the Mscorsvw.exe Virus may simply be acting as a backdoor for another virus, like for example ransomware. This is popular practice and shouldn’t be overlooked, which is why it may be a good idea to run a full system scan on your computer for other malware.

Another possible reason software like Mscorsvw.exe Virus or Altruistics may be on your computer is to provide cybercriminals with access to passwords, login details, online banking and financial credentials, and other sensitive information. This information, in turn, may be obtained through a variety of cunning tactics. For instance, Mscorsvw.exe Virus may be set to log your keystrokes (what you type in via your keyboard), or it may allow the hackers remote access to your computer, share your screen with them, provide them with access to all of your internet traffic, etc.

Trojans are also quite frequently utilized to turn computers into bots – also for a series of different reasons. For example, your computer could be made to mine cryptocurrencies for the hackers without you even suspecting it.

What you should be aware of is how you can protect your machine in the future. And aside from having a reliable antivirus program and keeping your system updated, avoiding known malware sources is a good way to go.
