I installed Avast Grimefighter on my Samsung laptop with Windows 7 and purchased the licence. Big mistake! I ran the software and it identified a few problems, which I asked it it optimise. After completing this, my computer restarted and now Windows cannot load at all.
When it is attempting to load windows, it fails and returns to give me two options of Windows Startup Repair or Starting Windows normally. The latter just gies the same result as above. If I select Windows Startup Repair, I get a message stating that Startup Repair cannot repair this computer automatically.
If I go to System Restore and select any of the backups, I cannot select the C Drive that is shown since it states 'You must enable System Protection on this drive.' So, I cannot use any of these backups using the System Restore tool.
Avast support suggested to use the last known Good Configuration, which I have also attempted. This produces the same result, i.e. fails and returns to give me the option of Windows Startup Repair or Starting Windows normally.
If I try to use Safe Mode to start, it gets ad far as loading aswRvrt.sys and then stops and returns to give me the option of Windows Startup Repair or starting Windows normally.
Any advice on how I can get my laptop working again would be much appreciated.
