Neighbour's PC with a free version of Avast

Running System Restore from the Advanced repair, all restore points fail. Safemode fails to load and Startup repair fails. Any help would be much appreciated. I'm hoping to avoid resetting to factory defaults, I think she bought MS Office through the preloaded one and I don't think she has any record of it.

That's the last thing that was loaded in safe mode, stops there. Can't get into Windows to uninstall anything.

Do you have windows repair cd?

Yes

I'd suggest running both chkdsk and sfc.

 

 

How to run chkdsk or System File Checker (SFC) from the Recovery Console

• Boot your Vista or Windows 7 installation DVD
• When you see "Press any key to boot from CD or DVD", press Enter.
• At the "Install Windows" screen, click on Repair your computer at lower left
• At the System Recovery Options screen, make note of the drive letter assigned to your boot drive (normally C: ) and click Next
• At the Chose a Recovery Tool window, click on Command Prompt. You will be sitting at X:\Sources directory.

Run chkdsk or SFC

• If you did not note the drive letter of your boot disk, you can enter bcdedit and look at the osdevice line to see what it is.
• For chkdsk, type chkdsk c: /r and press Enter (use the letter from above if not C: ).
• For sfc, type sfc /scannow /offbootdir=c:\ /offwindir=c:\windows and press Enter (use the letter from above)
• Let either run to completion undisturbed.

windows replaced bad clusters
aswRvrt.sys

 

How to get rid of avast now? Still won't boot.

[Ztruker]

You could try renaming the Avast folder under C:\Program Files or C:\Program Files (x86) (not sure which it will be under) then Windows will not be able to find any of the asw files so maybe it will boot. If it does, then rename it back and uninstall it as normal.

 

You would do this from the Command Prompt of the Repair environment like you did for chkdsk and sfc.
