I'm hoping the answer isn't to uninstall an reinstall as this would render the update button in the UI useless.
Thats what a clean install is, completely fresh.  The ui button isnt usless! it does it's job but sometimes for alleviating issues we suggest a clean install just to make sure there were no previous bug or coruption involved.

To clean install you must uninstall avast via remove programs then reboot into safemode and run the removal tool to eliminate remnants, then reboot back to normal mode and re-install the current AIS version.

Thanks. Understood.
Where is the removal tool found?

Possible solution
« Reply #20 on: July 07, 2012, 09:52:25 PM »
I have Win 7 64 bit with 4 GB RAM, fast dual core processor, fast HDD, etc. It started booting up slowly a couple of weeks ago.
 
Investigating this today, I discovered AvastSvc.exe has been triggering performance reports since late June. The longest delay was 57.6 seconds!

After doing a clean install of the latest version there were no performance events, but still close to two minutes from power on to a usable desktop. I rebooted twice more after re-registering and updating. Still no real difference.

After more research, I then ran "defrag.exe C: /b" (no quotes) from an elevated command prompt. The command runs Windows Disk Defragmenter with the parameter to place files relevant to startup in sequential order.

I found this site with a good explanation of the command and what it does: http://www.autoitconsulting.com/site/performance/windows-7-self-optimizing-boot-process/, or just search on "defrag.exe /b".

It cut boot time in half for me. Hope it helps!

Windows 7-64-bit: AIS: My boot up time after the update is ridiculous. Anywhere from 2-5 minutes. When my desktop is loading, first my screen turns black for about a minute and then it takes a good while for my icons and task-bar to appear. Anyone else having this issue after updating avast through the avast UI?

Thank gooness someone is having the same problem. I thought I had system problems since updating. Am also running Windows 7-64 bit with AIS and my boot up time and black screen etc mirror your experience. Have spent hours trying to tweek my system to improve boot up and can only conclude that it is Avast causing it. I also updated through the gui.

I also updated through the UI and my 64 bit computer has none of the symptoms described.
Guess I must be lucky or, something else is in the mix that's not part of my system.

If an update fails, there is always the possibility of an installation from scratch.

Seems normal. avast! and Comodo use network interaction drivers and this delay does not seem to be out of the normal range.

Ok ... After using Avast for a very long time, I too have come unstuck with this latest update.

Perfectly stable laptop, running Win7 Pro x64

Had just performed a cold reboot prior to updating my accounting software.  This restart was normal.  Prior to doing anything else, Avast announced the update.

Like others, a no brainer I thought.  Didn't get to update the accounting package.

My laptop has an SSD and usually boots in under 30 seconds, it is completely stable and well maintained. Until this update.  I am still staring at a spinning wheel and 'Welcome' after 6 minutes.  No desktop

How certain am I this is Avast related?  Given a normal reboot immediately prior, about as certain as you can be.

I will attempt uninstall / removal  in Safe mode (I can get a desktop) unless something happens in the next 5 minutes.

At this stage, this is more of a boot failure than slow boot.  Not happy.

4 other computers in the house won't be getting an update till this is sorted.

update, in case it helps someone else:
  • Booted into Safe Mode (no normal startup after waiting through 15 minutes of spinning wheel)
  • Uninstalled Avast via Control Panel
  • Ran Uninstall utility (outlined above)
  • Registry Clean (cCleaner) for good measure  --- doubtful this contributed to solution
  • Restarted (normal desktop, no problems)
  • Fresh Full download and install of Ver7 package

Modest increase in Boot time, within the realms of what I would expect.  Problem solved.
