Explorer.exe chokes CPU 100% during 2 mins from startup

    W98SE - 450 MHz AMD desktop. Conservatiive SwaPFileUsage set = 1.

    Once booted and AFTER all 6 apps have started Explore.exe chokes the CPU 100%
    during exactly 2 mins.

    One of its threads, FFxxxx, utilizes 100% of CPU power to do 'something.'

    Its STATE COLUMN (TaskInfo 2003) reads 'E-handlers', changing to 'Block' after 2
    mins.

    Then all quiet and hence good operations, CPU utilization 1-3% when idle.

    It is annoying since one wants to employ the CPU hardest shortly after starting
    up.

    What can this be?

    Any suggestions?

    Ciao, Maria

    There is no mention of you monitoring your swap file, or how much
    memory you have installed -- if you use the conservativeswapfileusage
    switch when your system consistently uses the swap file, performance
    WILL reduce. Use the system monitor over a number of days, and
    monitor the "Swap File in use".

    Hi MIke, the culprit appeared to be a trojan called Beagle/Bagel, trying to phone
    home or do other harm.
    It appears as a program file called 'winshost.exe' nesting in W:\SYSTEM.
    Once discovered and killed everythiung is back to normal
    Thanks, Maria
