Today i see that from the 6th February, every definiton update keep 450 mb from my hard disk. I can see in the avast directory from this date all the folder with the definition. The avast installation occupy now 8 gb on the hdd.
I can’t delete the older definition. I tried to repair the installation but nothing is change. What can i do now. I have no more free space to lose… Sorry for my bad english, it’s a little bit complicated for me to explaine the problem. :-[
Windows xp sp3, hdd 80 gb avast free 9. Hdd is ok, no error.
Someone can help me? Thanks.
Can you please generate a support package (as described here: https://support.avast.com/en-ww/article/Submit-support-file), submit it and post the package ID here?
Normally the old definition folders are deleted automatically of course, so there has to be something strange happening with Avast on your system…
Thanks.
I have found that the Avast Housekeeping isn’t running as it used to with several old DEFs folders still remaining on this XP system, but most of them only have the SWCUEngine.dll file. Invariably only the current and previous VPS folders are full.
Rebooting the system (which would ordinarily remain ON) does appear to work to remove old folders. On occasion there is still the current and previous defs folders remain and may be fully populated.
For MartinZ, disabling the Self-Defence doesn’t allow deletion of old folders, even disabling the avast shields doesn’t allow this. Previously I can recall being able to do this.
EDIT: Inclusion of defs folder image attachment after reboot.
Thank you to all. I see that the problem is more complicated as I thought. As soon as possible ( i write on this forum from another pc ) i will try to do what asked. I hoped to free the space as MartinZ told me. Now I’m fearfull and worried But really thanks. I se that the avast installation in the application menù use 8 gb of space… I’m confused… Sorry.
===========
Unfortunately the avast support tool give me an error. Maybe because my cpu don’t support sse2 instruction. The situation is now very complicated for me. I have no more place on the hdd, I add some images.
All the problems began on 6th february. Now i have no idea. How can I delete the old definitions folder without make a disaster, when and if is possible? In windows safe mode maybe? Thanks for any answer.
Did you try the manual deletion of the old defs sub-folders (first disable the avast self defence module) as suggested. I’m thinking this may still work in your older avast 9 version, unlike mine with a fairly recent avast18.5 version
Have you done a system reboot, as that for me clears dated defs sub folders ?
If so and no change.
3. Try an Avast Repair - Control Panel > Add Remove programs > Avast Antivirus - Change, from the next window select Repair. Reboot after the repair.
Ty for the answer.
I’ve just tried the point 3 unsuccessfull
I turn off the pc every day. So i make a new boot every morning. The folders you can see are the folder created every day.
I’ ll try as you tell me the manual deletion. If also this don’t solve the problem i don’t know…
You’re welcome, you’re bumping into having an old system and old avast version. Unfortunately most of the regular users on the forum haven’t used the version for years and things change.
Inside the C:\Programmi\Alwil Software\Avast5\defs folder, there’s a small file called aswdefs.ini.
Can you please open it (e.g. in Notepad) and post its content here? (There’s a value Latest=something inside - and I’d like to know if it refers to the latest folder you have on disk, or for example to the very first one - 19020600).
Also, could you please create a list of the files in the folders and attach it here? Just open a command line prompt (e.g. press Win+R and type cmd.exe into the box). Then copy&paste the following command to the command prompt: dir /s “C:\Programmi\Alwil Software\Avast5\defs” > c:\windows\temp\aswlist.txt
After that, please attach the file (c:\windows\temp\aswlist.txt) here…
Thanks!
Thank you all so much for your help As soon I can i’ll do what you told me. Today I have tried what MartinZ told me. I have deleted all the folders from february except the folder from 6th Feb. I have rebooted the pc and made the virus definition update ( the hdd was completely full ). I must see if all is gone good O.o
Hello. So, the content of my aswdefs.ini is this
[Definitions]
Latest=19020600
The same date of the creation of the file. I don’t know at the moment if my Avast work with the virus definition of that day, or with the updated defs. :-\ For Windows xp my antivirus is not updated, but for Avast ( read another file .ini ? ) is all updated.
Here is the file aswlist.txt. I hope it will be useful. I saw that this question of the date of the virus definition is not only a problem of mine. In the original post another guy quoted the same problem with the same date. 6th Feb 2019 :o
Thanks a lot for the info. I’m afraid it shows that your Avast is really using virus definitions from 6th February - any later are incompletely extracted on disk. That’s also why they are not removed - Avast always removes the definitions older than the ones it’s currently using…
Could I please ask you for one more file? Normally this does the support tool, but that’s not working on your machine. Problem is, I honestly don’t know where to find it on your machine… you having Italian Windows, plus the installation is updated from an even older version of Avast (so it’s “Alwil Software”, not “Avast Software” that the new versions got).
The file is called Update.log and it’s in a folder which, on English Windows XP, is called C:\Documents and Settings\All Users\Application Data
In that folder, it may be in AVAST Software\Persistent Data\Avast\Logs… but for you, it may be Alwil Software instead, and I’m not sure if Persistent Data will be there.
Maybe you could use Windows Search (Win+F) to find the location?
There’s one thing I would try to fix the problem - download the full virus definition update from https://www.avast.com/download-update and run it… chances are it may help.
Sorry for the troubles.
Thanks a lot for the help. I will search the file as soon as possible, unfortunately, I’ve just try to use the offline definition package. It was the first attempt after the repair function. I was worried that avast don’t use the newest definition. You confirm my suspect. You and all the people that asking me are so nice. Thank you so much. Using the removal tool and installing the last version available ( 10 for not sse2 cpu ) can be a solution?
Thank You so much
