System froze under 5.1.864

Avast Free Antivirus / Premium Security
1

I never had any problems with 5.0 but upgrading to 5.1.864 results to unexpected system froze. It was nothing special in processes - Firefox with multiple tabs, several copies of Far and Avast UI. It was nothing special - mouse cursor was alive but I can not swatch to another tab or scroll current tab. After Ctrl-Alt-Del I got usual light-blue backgraund for this soft reset but absolutely no buttons on this screen. Subsequent C-A-D gives nothing. After hard reset system is working.
Question: what I should do to give some additional info to developers about this froze?

do you update your avast throgh program update? if yes

uninstall it through removal tools then do a fresh install

But this is not the real solution of this problem. My system is working fine after reset. The problem is that there are some unknown conditions sometimes resulting to system froze. And the questing was: how to reveal these conditions?

I’m freezing as well same as reported here http://forum.avast.com/index.php?topic=67766.msg570645#msg570645.

Tried a few betas since plus release.

Never expected a problem with Avast.

Avast was the only security programme on my PC. Replaced it with Panda Cloud.

Please try disabling the startup rootkit scan in avast settings → Troubleshooting → “Enable rootkit scan on system startup” (uncheck the box and reboot the computer).

Does that make any difference?

Thanks

With disabled rootkit scan it works.

Thanks. We will (at least temporarily) fix this with a VPS update later today.

Freezing here too while using Opera 11. This is on an older IBM laptop (1G RAM, P4), Win XP Home SP3 and the only way to fix it is to pull the plug (or battery, if I’m using it) and power up again and reboot, then it seems ok.
I have not tried to disable the rootkit scan.
I run the file, web, and network shields.

I never had this problem with version 5.0, but will wait for the temporary fix?
Otherwise, back to version 5.0 :frowning:

I updated through the GUI.

The VPS update has now been released (110101-1). Please update to it and report back if the problem is solved.

Thanks

Updated to the latest VPS on the laptop, With anti rookit scan off, it works fine, but with it on, still freezes when attempting a scan with it on…

5.1.864,Clean install of Avast 5.1 and Windows XP, thought i had a hard drive problem last night lol

Problem Resolved–Thank you all so much, now to finish reinstalling all of XP updates

11

Do I have to keep the rootkit scan unchecked?
It seems to work with it checked.

12

You just answered your own question…! :wink:
asyn

13

I wasn’t sure because of bikemanAMD’s post.
So far, no problems.

14

I’m actually a bit confused by bikemanAMD’s post… he said “Problem resolved”, but 3 lines above that he said that the machine was still freezing… so I’m not quite sure how to interpret that.

In any case, the VPS update should allow you to avoid the hangs even with the default settings (i.e. rootkit scan enabled).

Thanks

Meant after updating to the new VPS, Problem is totally resolved VLK, sorry for the confusion

Have 6 Machines here, and even i was confused why the laptop was only one freezing, and then i read VLK’s post to update to the neW VPS, then i did that, and edited my original post and put in problem resolved, sorry i should’ve been more clear eariler all

16

Same here, out-the-box defaults settings working fine with new VPS.

17

Thanks for the confirmation guys.
