Csrss.exe causing heavy CPU usage

By makihara
Feb 18, 2010
  1. Hi,

    Suddenly found myself with a ridiculously high CPU usage (100%) which wouldn't go away on restart.

    So i did 3 things:

    - ran malwarebytes and it found a few things which i deleted
    - ran HJT and deleted aviwsglade entry
    - opened up msconfig and in startup i found Autoexec.bat and A1d.tmp which i unchecked

    I wanted to make sure i got the little bugger. Am i missing anything?
    How can i permanently remove the entries from my startup page in msconfig?

    Here is my log just in case:

    THANK YOU for any help you can give me...
