    Hi there. My browser homepage has recently started changing to: "mk:mad:MSITStore:C:\WINDOWS\start.chm::/start.html", sometimes a new window will appear while I'm browsing also at this address. I deleted start.chm, seems to have sorted the problem, but I was just wondering if anyone knew what could be causing this.

    Here's my H/T log incase it's needed:

    Hi Psycosis

    I've been having this problem too. If you read around on the net, it seems there are many others in our boat.
    All the ususal bits of software for dealing with this kind of thing aren't working. They appear to do their stuff, but not long after the hijack happens again. Deleting the start.chm in windows didn't work for me either, before long the home page was hijacked yet again.
    A work around this found on another forum, for the time being until someone works out exactly what's happening, is this :

    Open the start.chm file with notepad.
    Delete all the contents and save the file as the same name, ie. start.chm.
    Then make the file read only.

    With the file in the right place in windows, the hijack seems to be disabled, and not constantly being re-written.

    It's a bit worrying though isn't it, where this file came from in the first place. I thought I was well protected on the internet, but obviously not !!!

    This is my canned fix for it.......
    "fix" the entrie with HijackThis....Then Locate and open start.chm with notepad then selected everything and delete it......Save it and when it asks for overwrite click yes..... Now go back to C:/Windows and look for start.chm (if you can find it you may have to show hidden files.)......Once you find it right click....go to properties then mark as read only. Empty your Temporary Internet Files.. Click "Start" > "Settings" > "Control Panel" > "Internet Options" > On the "General" Tab. Click "Delete files" and check the "Offline Content" box and click OK. Now, disable Active X.....Go to Internet Options/Security/Internet, press "default level", then OK. Now press "Custom Level." In the ActiveX section, set the first two options ("Download signed and unsigned ActiveX controls") to "disable" and "Initialize" and "Script ActiveX controls not marked as safe" to "disable". This disables Active X completely.....and this can be a downside. For the moment........until a patch is released....or,get another browser instead of IE.....Opera www.opera.com is faster,better and a lot less prone to hijacking.

    Thanks for the replies guys.
    Yes, it is very worrying Choccy. I didnt download anything, so no clue how it got there, I ran norton antivirus, ran a-squared, ran adaware, and nothing was found.

    Which entry is it $teve? I looked through it before I posted it, the only thing I can see that looks wierd is the Toolbar and Radio... is this the one?

    Nope..............your log is not showing an entry...... possibly because you deleted it.
    how is your home page now?The problem will reappear.

    Homepage hasn't been changed for 2 days, with reboots and everything. The only thing I did was delete the start.chm file. Wierd. Thanks anyway.
