Windows 10: AVG watchdog preventing computer from booting up

Last night I noticed quite abruptly that many of my apps had stopped working and the computer in general was acting very slow. I restarted the computer, but after the inital Toshiba opening screen the computer went blank with a little spinning circle. After maybe a minute or two AVG Watchdog tries to initialize, fails, and appears to freeze the computer. Several times now I have attempted to boot into safe mode by pressing F8 and shift/F8 repeatedly as soon as I turn on the computer, but so far I keep getting the same result I outlined above.
I just made an account here to ask for help, and will admit that I know the basics but am not very skilled with this type of thing. If anyone has any advice it would be greatly appreciated.

Watchdog Black Screen

So, I've been getting this black screen every time i boot up saying something about creating keylist or some ****, something about watchdog, and it's been happening since i installed avg, i can still boot up perfectly fine, but it justs annoys me, every
time I boot up....

Please help!

 

Starting watchdog initiation on black screen

The AVG website reports the issue lies not simply with Windows 10 but with your Logitech Wireless Devices. It was recommened to remove any usb cables/dongles and re/start the pc/laptop.

Worked for me! Simple.

Now this issue of watchdog initialization error started after my laptop crashed just as i was changing the password. the answer from uByte would not work for me as (even though networking was enabled with safemode) airplane mode had been enabled (due to
trying to prevent a cloud service from deleting files i needed) and couldn't reenable it. additionally, the old password didnt work, but neither did the new one... ??

Working on it now i can log in normally though as, as i said, removing my usb hub containing my logitech wireless keyboard/mouse combo dongle bypassed the watchdog black screen. will however be uninstalling avg free to prevent this in the future (or until
an update from logitech -as avg claim is responsible- is released...

thanks for the help uByte!

 

AVG and Windows 10 Anniversary Update don't get on well together, apparently. See this (lengthy) thread which includes this solution from Ubyte...

Win 10 AU doesn't like much of anything it seems....*chuckle

 

Back in the day, when AVG was still new, I used it exclusively and shared it with all my hundreds of customers.
Well, that was then and this is now and AVG (free) has definitely become something else. I no longer use it and no longer install it for any of my customers.
I prefer to use use Windows Defender and then supplement that with 'Super Anti-Spyware', 'Spyware Blaster', Malware Bytes Anti-Exploit, and 'Anti-Logger Free' from Zemana. Using these programs, I and my customers remain Virus and Spyware free.

So there is definitely a good alternative to AVG.

Cheers and Happy Computing,

Thanks for the help everyone! Followed that thread and a few others and got it fixed. Uninstalled AVG and for now have Defender running while I look at other options.

 

Sorry, but I had to do this to read the OP's screen cap post, so I thought I'd share:



BTW, there's a thread on the AVG support forums that addresses this issue. Startup message about Watchdog Initialization? | AVG It's covered in the post from Kishore/AVG Technologies and advises a boot into safe mode (Reboot your computer into Safe Mode | AVG Support) followed by AVG repair (Repair AVG | AVG Support).

Call me a member of the "better late than never" club: I see you've already switched to Defender.

HTH,

Tried this twice now and the third restart after correcting AVG locks it back up again in this loop
