Title: Avast is hanging XP's shutdown
Post by: Peetah on November 15, 2004, 10:27:09 PM
Versions 4.5.518 and 4.5.523 is causing my system (Windows XP SP2) to "hang" when it's shutting down, forcing me to do a "hard shutdown" (hold down the power button).

The event logs have nothing in it.

If I shutdown the "Avast! Antivirus" service before shutting down the system, the shutdown process is ok.

However, if the service is not shutdown prior to shutting down the system, the shutdown process appears to "hang".

I can replicate this problem easily and it only started to appear when 4.5.518 was released.  Uninstalling and reinstalling has not helped.

Help!

Thanks

Can you try repairing avast from the control pannel, and have you tryed shutting off other programs before shut down aswell (such as your firewall).

Shutting down/killing programs prior to shutdown didn't help.

Repairing it doesn't help either.

Small update:

Right clicking on the Avast icon and stopping the On-Access Protection will let the system shutdown proceed normally.

Right clicking on the Avast icon and stopping the On-Access Protection will let the system shutdown proceed normally.

Which file is being scanned at that time?
Can you see this into the provider (on-access protection) window (last file scanned)?
Did you schedule any scanning that does not finished yet?

The last file scanned varies.  The last one was c:\...\tgbvpnlog000.txt  This is a log file for my VPN program.

Since I have re-installed Avast several times, no scans were scheduled or were in progress, performed or interrputed.

Just in case, I'm running a scan of the system right now.  If I find anything different after the scan, I'll post it here.

Also, I checked to see if Avast was scanning for a floppy, CD, or removable media at shutdown, and no it's not.  They are unchecked.

At least yours will shutdown after a minute.  Mine won't ever shutdown.  Even after 8 hours.

true a slow shut down is better than none

Sorry if the question is stupid but did you apply all Microsoft updates?
Some of them solved shutdown problems in the past...  ::)

I thought I was the only one....
Same thing here....takes about a minute or two to shutdown.

I read somewhere that SP2 has a special care while shutting down windows and security related applications (firewall, antivirus, etc.)...
But, you're right this should not happen... Maybe some other user could help you... I can't  :-[

Well, apparently, Avast got it right before they released 4.5.x.  It'd shutdown pretty fast in previous versions on the same system.

My guess is that Avast is not releasing a resource, or not telling the operating system that the resource it's holding is no longer needed.  Thus Windows thinks it can't shut down because it's unsafe to do so.

One thing I did notice is that when I check the: (about Avast)
I notice the product says: server.
I thought I was to chose workstation.
or does Avast make this a default and no problem is here?

Ok guys
I just upgraded to the latest Avast
4.5.523  I think
now it is shutting down after a 1 minute 10 second wait.
10 seconds slower.
a little worse, and still way to slow.

It's still occurring, even after trying different shutdown scenarios.  The only sure method of making my system shutdown is to shutdown on-access protection, or shut off the service.  Neither of which is acceptable.

It was working in versions prior to 4.5.518.  So something has changed between now and then, and it's not my system (except for avast upgrading itself).
