How to Remove Kaspersky Temporary files to Free up disk space

If you have Kaspersky Antivirus or Internet Security installed on your PC, then you will notice a 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).

Here’s how you can 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.

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.

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

    kaspersky is gud but i hate these temp files….

    anyway, thnx again….

  2. Rohan says:

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

    by the way thnx for he tip 🙂

  3. sameer says:

    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)

  4. jerry says:

    Thanks for this; hate trash kicking about my system.

  5. Mave says:

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

  6. Mave says:

    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?

  7. Mayur says:

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

  8. Mave says:

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

    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

  28. wings says:

    thanks buddy…i can save space more then 1G 😀

  29. Glyn says:

    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)

  30. NISHANTH says:

  90. JR says:

    I ended up uninstalling Kaspersky and getting rid of it for good. Noting but issues over and over. It eat up a little over 1TB of disk space in under 29 days. No thanks I was locked out of my computer for a couple of days due to no more space on C drive and it trying to protect its self from damage. I took 9 days to run a full scan and would crash all of the time. The only thing that worked part of the time was the root kit scan that was because it ran constantly all the other scans would start and stop after a couple of minutes. It would run updates constantly over and over to the point that I could not use my internet connection. And talk about a pain in the backside the Money, and Adult Account setting for every user being forced to instal the cap into my browser slowed it and Outlook down too. Overall have to rate it total Crap ware and stay as far away from as possible lots of bells, whistles, to make you think its doing something that its not. Not to mention the fact that once installed if you can’t find the help you need online or need to ask be ready to pay through the nose to troubleshoot a product not ready for market. In other words be ready to debug their product you paid for at twice the price once to buy and again to fix. Have heard stories of at least $69-99.99 per half hour for “Tech” support. To again fix issues that should of been fixed before being released for market. Anyone want to argue with me from the Company happy to take it up with you, have had it take mine and others Systems hostage refuse to let me on my own Computer.
