Boot-time Scan Halting Windows Startup
« on: January 11, 2012, 05:58:27 PM »
Hi

So I scheduled a boot-time scan after struggling with a virus that hid all my user files.

The problem is, the boot-time scan won't run, just gives me a black screen at the time of startup, and I can't get around it.
I even tried to F8 during startup hoping to get the windows options to skip it, or run windows in Safe mode, but nothing really happens.

I have windows 7.

Any ideas?

Thanks for getting back to me.
Thing is though, as I explained, I can't get into Windows. Therefore, I can't retrieve the requested logs or run the suggested applications (e.g. MBAM).

Reading information about the particular virus that started all of this here: http://www.myantispyware.com/2012/01/02/how-to-remove-system-check-virus/
I've found some steps to deal with it, but I just need to get back into Windows to do any of it. And to do that, I need to somehow circumvent or bypass the Avast Boot-time scan.

Perhaps if I boot from some linux distro running on a usb thumb drive I could modify any boot file that has the Avast boot-time scan flag? Wish I knew which file has this though.

When the Avast boot scan attempts to start press the escape key - that should kill it

If not then I will need to delete the registry entry for the Avast boot scan.
