Windows 7: Computer won't restart after uninstalling Avast software

Computer won't restart after uninstalling Avast software

Recently I made a decision to quit paying for Avast internet security and go back to Norton. In the process of uninstalling Avast, a box pops up saying to finish the uninstall you must restart the computer so I checked “later” as I wanted to get the Norton installed and protecting before I restarted. When I tried to restart my computer, a box popped up saying Windows could not restart and would try to repair, then it came up saying Windows could not repair and it went into a loop between these two things. I could not turn off my computer and the only way to stop this loop was to unplug it which I did. It said I had a corrupt file and the Problem Signature for 1 & 2 was 6.1.7600.16385, Sig 3 unknown, Sig 4 21200445, Sig 5 AutoFailover, Sig 6 8, Sig 7 Corrupt File, OS Version 6.1.7601.2.1.256.1, Locale ID 1033. I tried restarting using F8 and safe, and F8 safe with command and both would go immediately into this same loop when Windows started going across the bottom of the screen. One time a box popped up and asked me to sign in as Owner but it wouldn’t accept my password. It also wouldn’t give me a chance to put in my ID as the box would only say OWNER. I really need someone’s help. I found this site after Googling “trouble restarting computer after uninstalling Avast software” so have faith in your help.

The problem lies with the security credentials (logon) assigned to the Security Center service.

You could also try unplugging all USB peripherals, wait for a bit, then push the button to start your computer.

Thanks Jacee. I will try these. I am about to pull my hair out. I appreciate your help.

I went in to disconnect the USB connected items but not sure what you mean. I disconnected the external hard drive but (don't laugh now) my keyboard and mouse are also connected by USB. Should I disconnect them also? It's too late for the wonderful instructions on how to uninstall Avast as I already did that.

Sorry to bother you.

Just disconnect external drive and printer (if connected).

You're not a bother! .... we need to get you up and running again, without a 'boot loop'.

I disconnected the external drive and my battery backup. Thankfully, my printer is WIFI. Then I tried to reboot and it went into that cannot repair mode and was showing the exact same data I put in my original message. Should I try F8 and if so, which option and what do I do next? I really appreciate your help. I have been on computers since back when IBM wrote in basic language but have never seen anything like this before. I even built a computer from scratch (not a kit) in 2001 just to prove that a girl could do that. This has me feeling totally defeated.

Hi WebkinzDiva1,

Welcome to the Seven Forums! We'll try to help as best we can!

Do you have a Windows 7 Installation disc? If so follow these steps:

  1. Go into your BIOS (Either F2 or DEL on start-up)
  2. Find 'Boot Order' or 'Boot' (The names vary)
  3. Change the first boot device to your cd/dvd drive
  4. Insert your Windows 7 disc into the cd/dvd drive
  5. Save changes & exit
  6. The screen will prompt you: 'Press any key to boot from CD' < Follow the prompt
  7. Instead or pressing 'Install' press 'Repair Computer'
  8. Run the start-up repair utility
Let me know what happens

Unfortunately, my Windows7 came pre-installed on my computer and I did not receive a disc. I wonder why these are not included with all computers. I really appreciate your help though. Wish I had that disc.

Are you able to access another PC with a DVD drive?

Yes, my laptop which I am forced to use right now, has a CD/DVD drive.

That's brilliant. Follow my instructions below to create a Windows 7 Repair Disc - then follow the instructions from my previous post about how to boot from the CD (I will re-type the instructions below)

Windows 7 Repair Disc:


  1. Go To Control Panel\System and Security\Backup and Restore
  2. On the Left you will see 'Create a system repair disc'
  3. Select this and follow the instructions on-screen

Repairing your boot:

  1. Go into your BIOS (Either F2 or DEL on start-up)
  2. Find 'Boot Order' or 'Boot' (The names vary)
  3. Change the first boot device to your cd/dvd drive
  4. Insert your Windows 7 disc into the cd/dvd drive
  5. Save changes & exit
  6. The screen will prompt you: 'Press any key to boot from CD' < Follow the prompt
  7. Instead or pressing 'Install' press 'Repair Computer'
  8. Run the start-up repair utility
