mscorsvw.exe RRS feed

  • Question

  • I have upgraded Windows 7 and now mscorsvw.exe is consuming almost all my systems capacity.

    Immediately after the upgrade I made an image backup I will call BK1.IMG.

    I have researched mscorsvw this using google as follows:

    Mscorsvw compiles .net modules (I understand).

    At first it compiles high priority modules for around 10 minutes (I understamd).

    Then it compiles the rest of the modules running at low priority (I understand, but with a question).

    It has been running this way for 33 hours. When I log on mscorsvw stops for a while.

    Whin I log off it starts up again after say 10 minutes.

    How long is this process likely to take?

    It makes no sense to make a final image backup (BK2.IMG) until mscorsvw has finished.

    How long is this all going to take? Is 33 hours already too long? What to do?

    Thanks, Steve Broshears ...

  • Hi Steve,

    If you open task manager and then the CPU shows fine and not being consumed, then you may be infected with a Trojan.

    I recently had this problem, its now solved. 

    SUPERAntiSpyware Trojan.Agent/Gen-MSFake[Gen]

    The files guilty were: /Syswo64/sbs_wminet_utils.dat

    and /System32/SBS_MSCORSEC.dat

    PS: ONLY IF YOUR CPU IS BEING USED 90-100% at all times except when you open task manager.

  • Hi Steve,


    I would like to share the following article for your reference:


    What is mscorsvw.exe and why is it eating up my CPU? What is this new CLR Optimization Service?


    Hope this helps.

  • But my question is, how  long will it take?

    I don't want to make my second backup image

    until all the modules are complete,

    even the low priority ones.

    =====

    And I just thought of another thing.

    What software will not be working until it completes?
