How to Remove Kaspersky Temporary files to Free up disk space [Featured]

by Mayur on January 24, 2009

in How To's, Tips 'n' Tricks

If you have Kaspersky Antivirus or Internet Security installed on your PC, then you will notice loss of disk space. This space is mostly acquired by the temporary files that are stored by Kaspersky. I freed about 1.3 GB of space from my PC by removing these temporary files, which were around 200+ each having a size of 5MB (Approx).

You can also free up your disk space, by following the simple steps below:

1. Open Kaspersky Settings > Options and disable the Self -Defense option.


2. Now Exit your Kaspersky product ( KAV or KIS ).

3. Enable “Show Hidden files and folders” option from the folder options.

4. Go to C:\Documents and Settings\All Users\Application Data\Kaspersky Lab\AVP8

5. Open the “Data” folder where you will find many files named as av1A.tmp, av2A.tmp, etc. and other files and folder.

Properly select all the files having a .tmp extension and leave all other folders and files. Then delete all the temporary files ie. .tmp files. Make sure you don’t delete any other file. You will now notice a high reduction in your disk space.

6. Now Start Kaspersky and turn ON Self–Defense.

>> It is completely safe to remove these files as they are temporary files which have been used earlier by Kaspersky. I have tried it myself on my PC, So Don’t Worry :D

Update – Windows 7 & Vista users need to open this path: C:\ProgramData\Kaspersky Lab\AVP9\Bases\Cache to find the .tmp files and delete them.

thnx for this very useful info…..

u have helped me recover around 6.5gb of space…..

god!!! i didnt think it wud occupy this much space….

kaspersky is gud but i hate these temp files….

anyway, thnx again….


Rohan February 16, 2009 at 7:03 pm

In Vista the DATA folder would be at
C:\ProgramData\Kaspersky Lab\AVP8.

by the way thnx for he tip :)


sameer February 26, 2009 at 1:13 am

recovered 2.5 Gbs of space after doing this. Every kaspersky user not using the email feature should do this. Those tmp files are actually email files which have been scanned by kaspersky. Also disable the anti spam feature before this otherwise those files will reappear.( only if you dont use outlook, the bat! and thunderbird)


jerry February 28, 2009 at 12:57 am

Thanks for this; hate trash kicking about my system.


Mave March 2, 2009 at 1:25 pm

When I delete, it says, “Make sure disk is not write/ full protected” something… WTF!


Mave March 2, 2009 at 1:46 pm

For, every file, there’s an error when I delete. ACCESS DENIED… “Make sure the disk is not full or right-protected”… How do I deal with this?


Mayur March 2, 2009 at 2:20 pm

@Mave Make sure you have firstly disabled Kaspersky using the above described method. Then try to delete the files.


Mave March 4, 2009 at 8:30 am

@Mayur Thanks man… I was actually disabling “Enable Protection” instead of “Enable Self-Defense”… Problem Solved.


goutham April 26, 2009 at 9:44 am

Sandeep Khanna June 13, 2009 at 7:45 pm

Thanks a ton.I was really bothered with this issue and you really did a great job.The Kaspersky site is quite a misery and to even register is a pain if you are not an American resident.

Thanks once again

Dhavish June 19, 2009 at 3:32 pm

where will this enable self defense option be in internet security 09


Savy August 18, 2009 at 12:21 pm

Excellent. Truly wonderful.
I had to once re-install the C drive since I was running out of space.
These files have took about 10 GB and I couldn’t delete them.
Again after that these files are building up . Your trick worked and I was saved from re-installing again


HARI August 19, 2009 at 1:33 pm

thanks man,
i had recovered 3.5gb from c:/
my probs get solved from this huge memory loss.
thank you once again

wings September 8, 2009 at 7:57 pm

thanks buddy…i can save space more then 1G :D


Glyn September 14, 2009 at 4:41 pm

I figured this out and just deleted all starting with AVP8 (except the initial briefcase). Seems to be fine now and has freed up an incredible 15 gigs …thats just after 7 weeks ! ….Why doesn’t Kapersky dump these automatically from time to time? Lol I thought my comp was slowing down. Come on Kapersky ..this is a bit whatever eh!
P.S. Just do it as outlined above and don’t worry, it still works without all this damned data. (Bitdefender doesn’t do this, but it ain’t good ….so slooow)


NISHANTH September 20, 2009 at 11:19 am

thank u.. it ws very use ful… i freed about 6.10 GB 0f my disk space…

but still the kaspersky lab folder is of 3.3GB.. is it possible to delete any other files..

plz let me know


jayb September 30, 2009 at 7:31 pm

kaspersky Internet security 2010 doesn’t have temporary files…. maybe all 2010 products…. I think they fixed this issue already


Mayur September 30, 2009 at 8:29 pm

No Kaspersky 2010 products also include this issue. Just checked my KAV 2010 in Windows 7. See Here C:\ProgramData\Kaspersky Lab\AVP9\Bases\Cache

It didn’t work with my computer, “Cannot delete av**: Access is denied”. How can I make sure the disk is not full or write-protected and that the file is not currently in use?

I’m using Kaspersky Internet Security since 2008, the temp files accumulated are now close to 30G.

Pls help. thanks in advance.


josee October 23, 2010 at 12:04 am

i think that you have to disable self-defense


saurabh December 2, 2010 at 3:34 am

Even after Disabling self defense. The Error is still persistent, even with my Desktop.
