Avast Broke Windows 7

    Alright guys, I'm in need of some very quick help. I've broken my mother's computer and she's not happy about it.

    We had a very severe issue just the other day, and I rolled the computer far back to fix it. Then I installed the free edition of Avast, and it detected a Virus. I followed the protocol, deleted it and told it to go ahead, restart and run a root kit scan. Now windows will NOT start. It brings up Windows is Loading Files, fills a grey bar white, then the bar flashes grey and after four hours, nothing has happpened. HELP! I've tried system restores from a repair disc, but they all have 'unspecified error'.

    I'm entirely at a loss as to what to do. If I sound desperate, it's because I AM. :cry

    No joy, it just goes to the loading files thing and stops. I've tried rapidly pressing and holding the button. Nothing.

    I'm not sure how Avast fits in. Maybe doing a chkdsk would allow things to go further than the loading files screen.

    From the repair disc it should show your Win 7 drive letter in the box after it searches for problems. Then go to the screen where you found system restore and command prompt should be the last option there. Choose command prompt and use the following command substituting your Win7 drive letter for C:. When that finishes see if it goes further than the loading files screen. A 5 minute wait is the maximum time to expect a change after it says loading files.

    chkdsk C: /r

    I'll give that a shot. Avast fits because it asked me to delete a file and then windows didn't work.

    Hi Triaxx,

    You should be displeased with the infection you had/have, not Avast.
    Avast was only trying to help ;)

    Do you have a flash drive? If so, you can try the below to obtain a FRST log.

    [​IMG] For 32-bit (x86) systems download Farbar Recovery Scan Tool and save it to a flash drive.

    Okay, so I installed Linux for temporary use, and then was able to get that to start it and run chkdsk which fixed the problem. Thanks for the help.
