Having searched the forum, I'm having the same problem after Avast Free failed during an update.
Can't boot into safe mode or restore.
I've attached the results of the FRST scan. Perhaps some kind soul could help me uninstall Avast and get my PC back up and running.

You will need to repair or reinstall Avast on completion of this
Download the attached fixlist.txt to the same location as FRST
Run FRST as before and press Fix
On completion reboot to normal windows
Reinstall Avast
Download Uninstall Utility (http://www.avast.com/uninstall-utility) to your Desktop.
Download the correct version of Avast
Avast Free (http://files.avast.com/iavs5x/avast_free_antivirus_setup.exe)
Avast Pro (http://files.avast.com/iavs5x/avast_pro_antivirus_setup.exe)
Avast Internet Security (http://files.avast.com/iavs5x/avast_internet_security_setup.exe)
Avast Premier (http://files.avast.com/iavs5x/avast_premier_antivirus_setup.exe)
Disconnect from the net
Uninstall Avast via control panel
- Run aswClear
- It will offer to reboot to safe mode .. Accept that

Many thanks, essexboy. Worked a treat.
-
My pleasure
-
OK. So after running aswClear, it did ask me to reboot in safe mode.
It seemed to successfully remove Avast Free.
Here's where my next problem started - I can only boot in Safe Mode, no matter what I try.
Any suggestions?
-
Was this after you removed Avast using aswclear.. I.e. it did not reboot to normal mode
Could you try the repair start up option please
-
Correct - immediately after removing Avast using aswClear, it failed to boot in anything other than Safe Mode.
Tried repair startup, system restore, tried uninstalling and reinstalling Avast, tried modifying the startup options using msconfig, chkdsk c:/r, sfc/scannow. So far nothing has worked.
-
Have you access to the safe mode menu (press and hold F8 at start) and select "start windows normally"
-
First thing I tried. It still boots in Safe Mode regardless.
-
when windows has loaded,
go to start>run> type "msconfig"
go to the "boot.ini" tab and deselect the option "/SAFEBOOT"
-
As I mentioned in my post yesterday, I've tried this. The Safe Mode is unchecked. However, I have noticed that my OS is not listed and I have no options to change services/startup options Furthermore, my MS Office applications shut down immediately they are started quoting an inability to verify the licence.
It's all starting to sound fairly terminal and I may have to reinstall Windows, which I had hoped to avoid. At least the majority of programs and data are on different partitions/Physical drives.
-
Try option 3 on this page http://www.sevenforums.com/tutorials/69585-safe-mode.html
-
Wow - what a saga!
Well that worked and my PC now boots in normal mode.
Except, now it won't connect to the network. If I run the trouble shooter, it thinks that there's a network cable unplugged - but there is not. Tried uninstalling and reinstalling the network card - no joy.
Thanks for all your help so far. I think I'm close to being fully functioning thanks to you.

It looks as though the bcdedit failed to revert for some reason after the safe boot, it should be run once only
Lets have a quick look with minitoolbox
Please download MiniToolBox (http://download.bleepingcomputer.com/farbar/MiniToolBox.exe), save it to your desktop and run it.
(https://dl.dropbox.com/u/73555776/minitoolbox.JPG)
Checkmark the following checkboxes:
- Flush DNS
- Report IE Proxy Settings
- Reset IE Proxy Settings
- Report FF Proxy Settings
- Reset FF Proxy Settings
- List content of Hosts
- List IP configuration
- List Winsock Entries
- List last 10 Event Viewer log
- List Installed Programs
- List Devices
- List Users, Partitions and Memory size.
- List Minidump Files
Click Go and post the result (Result.txt). A copy of Result.txt will be saved in the same directory the tool is run.
Note: When using "Reset FF Proxy Settings" option Firefox should be closed.
-
OK. Here's the result.
-
Have you deleted the network card from device manager, then rebooted and allowed windows to reinstall it
-
OK. Done that. As before, my network icon has a red cross through it and hovering over it says "not connected - no network connections are available"
-
Could you right click the network adapter and let me know the make and model please
-
Realtek PCIe GBE Family Controller
-
Is this a desktop or laptop ? What is the make and model
-
Its a desktop and it was built by PCSpecialist.co.uk. Pretty much custom built from a series of options choices.
-
hi Crackity Jones,
I think what essexboy is looking for is hardware configurations, esp. since custom-built and not your standard OEM product. Motherboard info, integrated NIC card used or add-in slot, etc.,. Once he has that info, should be better able to assist you.
You can always use Belarc Advisor to get the exact configuration info for your system. No need to post entire html document, just post what you think is needed.
-
OK - sorry.
Motherboard: Gigabyte Technology Co., Ltd. P55M-UD2
NIC: as mentioned is Realtek PCIe GBE Family Controller and integrated
OS: Windows 7 Ultimate (x64) Service Pack 1 (build 7601)
Anything else you need to know, let me know as I've run the Belarc Advisor now
Periodically Network and Sharing Center changes to "Identifying" and then reverts back to "Not Connected - No Connections are available"
I've tried a different network cable, even though there was no problem before the Avast update hung the PC and the problems started but the same result.
I've downloaded the most recent driver for the Realtek, but no change.
If I run the Windows Network Diagnostics Troubleshooter it says"Plug an Ethernet cable into this computer" Obviously, one is already plugged in.
I've run ipconfig /all and that seems to confirm the above - sometimes it says "Media disconnected" another time it gives a result.
-
Could you do the following please
1.To open a command prompt, click Start and then type CMD in the Search programs and files.
2.Right-click CMD.exe icon in Programs and choose Run as administrator.
3.When the User Account Control box pop up, click Yes.
4.At the command prompt, copy and paste (or type) the following command and then press ENTER:
netsh int ip reset c:\resetlog.txt
Reboot and then try again using the trouble shooter
-
No change, I'm afraid.
-
OK - I'm now back up and online as evidenced by the fact that I'm posting this from the PC that had all of the problems. The solution proved a lot simpler. Here's what I did:
1. Powered down the PC.
2. Removed the power cable and ethernet cable.
3. Wait 20 seconds.
4. Re-insert power cable.
5. When PC fully booted, re-insert ethernet cable.
Hey Presto, connection detected and back online.
Many, many thanks to essexboy for all your help and patience.

Glad to hear you found a solution, computers are sometimes just plain contrary :)
