Explorer start up/shut down & wuaclt.exe

  1. Hi.

    Recently I am quite certain I got nailed with a virus or two. My task manager has an ever growing collection of "wuaclt.exe" files in it whenever I run my computer. I have seen on many sites that this is a virus, but I can't find any one that tells me how to remove this file to stop the obvious re-infection/growth. I need advice to delete it. Spybot, Adaware don't even recognize it. Hijack this finds it but can't remove it or help me find it except when it's running.

    I also had the "libsys32.exe" running which also came up as a potential virus. I think I finally got rid of it, except for one file which I renamed and it seems to have become harmless for now.

    The upshot of these problems is that when I start my computer, Explorer starts as normal, then shuts down. A second or two later, it restarts and then stays open for a limited length of time (less than 2 minutes, but usually more than 10 seconds). I don't know where and how to fix this problem. I've never seen this before and have been running my software through the task manager since it started. But now, when I disconnect from the internet (done by ending the process for the "pctspk.exe"), the task manager locks up and I have to reboot by the power button.

    Any ideas on how to fix this issue, or free software that isn't incredibly crippled to uselessness to fix registry errors would be greatly appreciated.

    You need to use a bootable virus removal solution.

    download this rescue disk:

    The file will will be an image file that you burn onto a cd using your burning app: if you do not have one download free one from this site:

    save the rescue disk on your desktop open imgburn and select the image file and burn it on a blank cd.

    this link downloads exe version that automatically burns the disk without any other burning software:

    Boot the cd: >select start rescue system and use the up/dn keys to navigate the options and the spacebar to tick or untick your selections.
    i suggest you select full scan and attempt to repair infected files.

    First things first - rid system of insidious virus attack.

    "you said" = Recently I am quite certain I got nailed with a virus or two
    My first suggestion when dealing with an obvious virus/spyware attack is to go to the Updated 8 step process listed here: You may be tempted to skip a process or two. I would recommend that you resist temptation. Often as not this 8-step process will heal much of what ails you. :grinthumb

    Good guide! I know that virus, it prevents you from doing anything on your system and at startup it runs multiple wuaclt.exe processes at 100% and locks system.

    even in safe mode it just locks up system. So effectly you have no control over system to perform any scans or disable anything.
