Normally, when I run into a PC problem, I'm quite capable (or lucky) to solve them.
With the latest Avast Free update, I'm getting stuck because it seems to be a bit weird.
I'm running Avast Free on AMD 64 with XP and SP3 fully updated.
Right after installing the upgrade 10 days ago this is what happens.
The first startup of the day, after exactly 4 minutes, the screen freezes, no mouse response,
no keyboard response and no disc activity.
The only 'cure' is a hard reset (power switch off and on again), after that the PC runs fine.
When turning on the PC the next day, same thing. First start up, PC freezes
after 4 minutes, hard reset, PC runs fine. The freeze happens regardless whether
a program (i.e. browser, mediaplayer) is running or not.
I looked through the system and Avast logs, nothing there at the time of freezing.
There are entries from MS Defender that avastTestService was detected making changes to the system.
So I disabled Defender, no change.
I also did a repair on Avast, no change
Also ran a full system scan using Avast, both safe mode scan and start up scan, nothing found
(freeze doesn't happen when Avast runs a start up scan only after log in to XP)
Next was Superantispyware, with the same result, nothing.
Then I ran Autoruns (MS), which showed some invalid registry keys and some missing files and repaired those.
Removed all start up programs, only keeping the ones necessary for the system, no change.
Planner is checked for possible hidden task, starting after start up, nothing there.
The only program active (as seen in taskmanager) at the time of freeze is Avastsvc.exe, taking about 3-4 % CPU load.
The only positive at this moment is that my PC is faster than ever before, but
I'm at a loss, so any help would be greatly appreciated.
-
What is MS Defender ???
How much RAM does the system have ???
-
Sorry, I meant Windows Defender and it's 3 GB of memory
-
I do not run Windows Defender on XP as it is un-necessary.
-
That may be, but it most likely not the cause of my problem either,
since Defender is disabled and the problem persists.
-
Even with it disabled its drivers have to load.
-
What version of Autoruns are you using ???
-
It's Autoruns v10.06
-
Make sure there is nothing in Applnit
-
AppInit is empty for system, user and administrator
Some additional info:
AMD Athlon64 3500+ 2.21GHz 3GB, 2 x 160 GB HDD
XP home + SP3, IE8 + Avant Browser, SAS, Avast v5.1 Free

Do you have the BITS, Background Intelligent Transfer Service running and set to auto?
Do you have Comodo Firewall 5.3 installed?
-
The BITS function is required for windows update, no BITS running no updates.
-
So, yes on BITS :) and no on Comodo, only the standard windows firewall
-
Have you un-installed Windows Defender ???
@ wtfwtfwtf
As you do not know what you are talking about please do not offer advice! ::)

Every other time iv seen this lately uninstalling the behavior shield has helped, control panel/add remove program's, double click avast and scroll to change and untick the BhS, click ok and reboot.
-
I saw that possible solution in another topic, uninstalled BhS, first start up today and PC still freezes :'(
Going to uninstall Windows Defender, but have to wait till tomorrow to see whether that's effective or not. I'll be back
-
Turned out I didn't have to wait. It's update tuesday and, after installing
a bunch of Windows updates and removing Windows Defender, I restarted the PC and
the system froze exactly 4 minutes after login.......aaaarrrgh.
Restarted again, runs as usual. Any idea would be very welcome.

Since I can't stand having mysterious problems like the one described,
I've been fiddling around to see if I could produce the system freeze
intentionally, and I did manage.
If I start the predefined fast scan from the Avast interface, Avast scans
with no problem. However, if I turn on the PUP option, the system freezes
after a few seconds. And it is reproducable, PUP off - scan's fine,
PUP on - system freezes. Tried it at least 6 times to see whether
it's any particular file causing it, but the freeze happens with different
files although its always one of the .sys files in windows\system32\drivers.
I hope this info sheds some light on the issue.
-
Or should I just give up ::)?

hey goto avast settings -- troubleshooting and enable : load avast after other services.. this is recommended because, even if avast hangs/freezes or watever, your windows wil be working fine , and allow u to repair avast, reinstall..
now press start button- run- type services.msc . search for avastsvc.exe.. if its status is started/stopped/starting reply back. i think we have similar problems
-
Done that, under services Avastsvc.exe is shown as started, which by itself is not unexpected.
-
I cant say for sure, but I got this problem after running the opera 9.5 beta. It hasnt happened since I uninstalled it. Just a suggestion.
-
in case u dint find any solution to this problem , u can try this
hope u dint have problems in prev versions of avast. goto safe mode of xp, by pressing f8 while booting, uninstall avast from control panel and install 5.0.677. this build is pretty stable
http://www.filehippo.com/download_avast_antivirus/8292/
after installation keep prog update as manual
i too had similar problem, the desktop took 5 min to load after booting, which was solved when i kept the xp service named 'eventlog' as automatic in services.msc.. may be it can work for u :)
-
Haven't installed the older version yet.
All the changes I've made to my system do show some effect,
i.e. instead of freezing 4 minutes after logon, it now freezes
after 8 minutes after logon.
Not sure whether that is a real gain :-\
