After todays virus update my laptop no longer boots

Hello Brett. I sincerely apologize for the inconvenience caused. I certainly understand your frustration. In this case I will escalate this to our technical team.They will communicate and assist you further regarding this.

This update worked fine on my desktop, but when the laptop tried to reboot after the definition update it never came back.

This is on a Toshiba Satellite with an Intel i3 Processor, running Windows 7. It is a few years old at this point, but has been working fine until this update.

When booting, the Starting Windows screen comes up, but then the hard drive light stops and it just sits there.

I have tried System restore. It successfully restored to a point a couple of days ago, but it still wont boot. Startup Repair "cannot repair this computer automatically", and recommends that I send information about this problem; but how am I supposed to send information when the machine won't boot?

Problem Details looks like a bunch if irrelavent info, but here it is just in case this means something to someone else:

Problem Signature 01:     6.1.7600.16385
P S 02:     6.1.7600.16385
P S 03:     unknown
P S 04:     21200574
P S 05:     AutoFailover
P S 06:     4
P S 07:     NoRootCause
OS Version:     6.1.7600.2.0.0.256.1
Locale ID:     1033

Obviously, I tell it Don't Send, and it leaves me with either "View diagnostic and repair details" or "View advanced options for system recovery and support". Under View diagnostics, Startup Repair shows most results Completed successfully. Error code = 0x0

There is a Root cause found:
System volume on disk is corrupt.
Repair action: File system repair (chkdsk)
Result: Completed successfully. Error code 0x0
Time taken = 1950403 ms

and

Root cause found:
Unspecified changes to system configuration might have caused the problem


Everything was fine until AVG asked for a reboot.

So under view avdvanced options for system recovery, I have already tried Startup Repair 4 times, system restore once, system image recovery doesn't work because I don't have an image file and the DVD drive doesn't work anymore anyway.

Right now I have opened a Comand Prompt window, and the machine recognized a thumb drive at the USB port. I also have access to C: drive and it appears to be functioning properly. I did a quick test copying files from C: to the thumb drive, and it worked fine; so I hooked up a 1TB external hard drive to the USB port and I am currently backing up all the files while I have access to them. After I have all the data and documents copied, I will try to find these minidump files I have seen reference to in other posts so I might pass them along to whoever needs to see them at AVG.

It may take hours though, to copy all the data off of this machine, so I'll post my question(s) now:

Has anyone else had this problem with a recent definition update?

Any ideas what is going on here? This laptop has never had an issue with AVG, and has been running it for years now.

Any ideas on how to get this machine to boot correctly again? My next option is the Toshiba Recovery Wizard, which says it will destroy all my data. I'd really rather not go there if I don't have to.

My primary desktop took the update without issue. My secondary desktop is now asking to restart, but I have postponed it until I have some idea what is going on. I have 2 other computers running AVG that I am sure will ask for the update as well; and I cannot afford to have this happen with any others.

Thanks in advance, for any help this community can provide. I really like AVG, and hate to have something like this shake my confidence in the product; but this laptop is actually my wifes, and if AVG is the cause of this issue I will have to remove it if I can't find a solution.

Hi Brett,

This is really strange. I'm glad to hear you've already backed up all the important files. In this case I'd recommend inserting the Windows 7 installation disc and running the repair installation. It should not harm your files but some programs may stop working and will have to be reinstalled later.

Thanks
