Terrific 8)
Is there anything I should do to prevent this kind of thing happening again?? As you can imagine it's been a distressing few days for me :p
Unfortunatelly, we cannot know what caused this, sh*t happens. I had this problem few weeks ago, PC worked normally previous day, in the morning system won’t load. I spent several hours trying to fix it, using BIOS, Startup Repair, setting partitions as active, rebuilding boot and mbr, various other CMD commands, and succesfully fixed it. What caused it I don’t know, and honestly, I don’t give a damn ;D
I would recommend you to uninstall avast completely, then clean the possible remnants with this tool, and then reinstall it again.
But before that, let’s scan the system, and make sure everything is all right.
Please download Farbar Recovery Scan Tool by Farbar and save it to your desktop.
Note: You need to run the version compatibale with your system. If you are not sure which version applies to your system download both of them and try to run them.
Only one of them will run on your system, that will be the right version.
[*]Double-click to run it. When the tool opens click Yes to disclaimer.
[*]Under Optional Scan ensure “List BCD” and “Driver MD5” are ticked.
[*]Press Scan button.
[*]It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
[*]The first time the tool is run, it makes also another log (Addition.txt). Please attach it to your reply.
Then…
Please download GMER, AntiRootkit tool from the link below and save it to your Desktop:
