I hope someone may be able to help me with my question . For the last few days I have had problems with avast updating engine and virus definitions and program version. I keep getting the following message
avast.setup. the instruction at "0x004c5c12"referenced memory at “0x00000000” the memory could not be read
it asks me to either terminate to click ok or click cancel to debug…but then nothing happens except avast becomes unresponsive.
I did run a full system scan and nothing was found.
Can anyone help please ? my current version is 7.0.1451
I have been having the same problem. The avast support guys I’ve emailed more than 7 times have not been able to solve the problem either. Am about to dump this utility
Thank you for your replie. In some way It’s kind of comforting to find out that you have been having the same problem as it puts my mind at ease slightly as I thought maybe I have a virus which AVAST can not detect.
Was you ever told by AVAST to uninstall and re-install AVAST ? because I was thinking of doing this to see what happens but if you have tried this then there maybe not much chance of it working for me either.
First try a repair of avast:
XP - Add Remove programs, select ‘avast! Anti-Virus,’ click the Change/Remove button and select Repair, click next and follow.
Vista, win7 - Control Panel, Programs & Features, uninstall a program, select ‘avast! Anti-Virus,’ click the Uninstall/Change and select Repair, click next and follow.
I too have been recieving the same message when trying to do a manual or automatic update,just recently updated to Version 7.0.1451,now can’t update V.7 or definitions,what to do?
Anyone posting in this thread with a problem needs to let us know what version of Avast they are using for us to help you. For example are you using v. 7.0.1451 and upgraded or did a clean install, or are you using 7.0.1426?
Did your problem start after you upgraded or before that?
When you get an error message, tell us exactly what it says or take a snap shot and post it.
If you tried an Avast Repair then rebooted, did it resolve your problem or not? If not, what is wrong (be specific)?
Tell us what your OS is and if you previously had another AV on this machine. If you had a previous AV, how did you uninstall it?
If you already did an Avast uninstall, did you use the Avast Uninstaller tool http://www.avast.com/uninstall-utility or do it some other way (explain if you did it another way)? What problems still exist after doing this (be specific).
I have been told to uninstall and reinstall. Di that twice and the problem still comes back. I was then asked to send some log file which I did and till today no help has come ffrom support.
The problem is that the system cannot perform an update on the virus defination or a program update
When we manually execute the update after a few seconds a dialog box (avast.setup-Application error" come up with the following statement
The instruction at “0X004c5d42” memory at “0X000000” The memory could not be ‘read’
Click on Ok to terminate the program
Click on cancel to debug the program
When we click on the cancel (to debug), we get another diaglog box with the following statement
The instruction at “0X004c5d42” memory at “0X000000” The memory could not be ‘read’
Same problem here.
Windows XP
avast program version 7.0.1451
Problem began after getting avast’s false positive of cercsr6.sys as Sirefef-AAP [Rtk], although I suspect that is not related to this problem.
It’s possibly just a registry error and I’m waiting for my Advanced System Care to update before scanning for registry errors. (We only have dial-up internet here… kinda slow!)
Update: Advanced System Care failed to fix the problem. So now I not only can’t update avast, but I also keep getting pop-ups that tell me about a false positive because the correction that avast made can’t be updated into the program! If avast included an option to ignore the false positive instead of confining it to the virus chest or deleting it, then it wouldn’t be so bad. Very frustrating… I hate to abandon avast for another AV program but I might have no choice.

Is there any link to some technical details in the error message ?
Hello Igor, this is the error message I always get when trying to update virus/engine and program —
"avast.setup. the instruction at “0x004c5c12"referenced memory at “0x00000000” the memory could not be read”
This message appears as soon as my PC is booted and when trying to update manually or automatically
my current version is 7.0.1451
when I try and repair the program I get the following message–
ERROR PROCESSING PACKAGES.PLEASE YOU FULL UPDATE
Does this mean uninstall and install a complete new AVAST package ?
Also I have not uninstalled AVAST or recently installed the software I have been using AVAST for years, It all of a sudden within the last week or two been giving me problems. I’m using Microsoft Windows XP Home Edition Operating System Version 5.1.2600
No, try the manual update using the full virus definitions.
Manual update of VPS - avast! Virus Definitions Update - Manual Download VPS Update (virus definitions, vpsupd.exe, approx 31MB). - Save the file to your hard disk, locate where you saved it and double click it and that should carry out the virus definitions update.
Note: Ignore the file name in the images of the page that is displayed after clicking the download link, they are for the main program, not for vpsupd.exe which will be downloaded.
Ok so I downloaded and attempted to update via the VPS - avast! Virus Definitions Update - Manual Download link. When I tried install I got a message saying the virus definitions are already up to date.
So why do I keep getting red pop up windows in the right corner saying that AVAST can not update virus definitions and to try manually and then I get the error message
"avast.setup. the instruction at “0x004c5c12"referenced memory at “0x00000000” the memory could not be read”
and I also get this at least 3 times from boot UP of the PC.
The error message asks me to click ok to terminate the program or cancel to debug but nothing happens.
Ad:)
It will need more input by Igor as I’m just an avast user like yourself. What has been suggested has normally resolved the update failure followed by the repair failure.
Same issue (((
Win7 64-bit, Avast 7 free…
Try full scan, boot scan - nothing. Repair - failed with instruction at “0x00115c12"referenced memory at “0x00000000” the memory could not be read”
Now it says htat it is updated, but 3 shields turned off and I couldn’t turn them back on…
Malwarebytes quick scan - nothing.
Just one note - my CCleaner usually finds out some registry issue with avast, never paid attention on this -
Invalid file reference ImagePath - “c:\program files\avast software\avast\afwserv.exe” HKLM\SYSTEM\CurrentControlSet\services\avast! Firewall
may this be the case?
The download is a zip file, you need to extract the procdump.exe file to the root (C:) folder.
Then it is pretty much as explained before:
If when you open the cmd prompt you aren’t in the C:\ folder type cd C:\ and enter.
Now type the c:\procdump.exe avast.setup and enter.
This should then create a .dmp file, which will also be in the C:\ folder.
I don’t have a problem, so I just tested this tool using avastUI.exe as the target process to dump, I forgot to disable the self-defence, before I ran the command you need to do that.
See image example (click to expand) when used with avastUI.exe as the target you should be using the c:\procdump.exe avast.setup command string. It will show the name of the .dmp file once it is written.
