Avast wont run or uninstall after upgrade

I have windows 7 and use avast pro. And have tried the malware cleaning tools, but it still will not work. I have also tried to delete the avast folder, but some did not delete.

When I try to run avast installation it produces the following error: The exception unknown software exception (0xc06d007e) occurred in the application at location 0x761cb727

I attach certain results

It gives me the stated error when I try to remove it via control panel. When I run the clean tool it also give the same error. As soon as I do something related to avast that error pops up :o.

Could you attach the main FRST log and I will try to remove it manually

as requested.

This must be run from safe mode otherwise it will fail

When I try to run the avastclear.exe, I get same error message, as the previous user got.

Please download Farbar Recovery Scan Tool and save it to your Desktop.

Note: You need to run the version compatible 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.

[*]Right click to run as administrator (XP users click run after receipt of Windows Security Warning - Open File). When the tool opens click Yes to disclaimer.
[*]Select additions at the bottom
[*]Press Scan button.

[*]It will produce a log called FRST.txt in the same directory the tool is run from.
[*]Please attach both logs generated.

Thank you for your help. Attached are both of the files.

This fix must be run from safemode otherwise it will fail

Then run the avast utility

Great, THANK YOU SO MUCH! Did you want me to post the log first, and have you take a look at it before I run the avastclear.exe?

Nope run avastclear

So, it did manage to get rid of Avast, which was awesome! However, it gave me a blue screen of death, and the bootloader somehow got corrupted. I managed to get that fixed via the command prompt off a Windows Recovery Disk. Once I got the computer loaded, Avast was gone, and I ran the avastcleaner.exe and it removed the remaining files. Thanks for all of your help!
