    That is unsettling.

    Panda Antivirus bricked my Windows 7 install several weeks ago. No one should ever use any Panda products because they have demonstrated a level of incompetence so extreme it’s almost deliberately malignant.

    This is not even a new issue that only just appeared with the new update. I and others have experienced Panda Antivirus completely borking Windows long before. I even recall this issue with Panda happening to expert testers who were doing an antivirus product comparison in PC Magazine or a similar publication. Panda borked one of their computers entirely.

    This cannot be stressed enough: Absolutely no one should ever use Panda Antivirus or any other Panda product.

    Oh, that’s concerning. Hope your system has recovered now. Thanks. Ankit

    Thanks for your comments, you are correct that this is not a new issue. There has been many instances in the past when other AV programs have deleted Windows files.

  6. Yes I was one as well huge problems I reformatted in the end and used another antivirus, i wiped the cost and put it down as a bad experience

  7. I tend to agree with you

    I’m in luck then, i use the antivirus and haven not encountered the problem and it shows is up to date, but i will do a back up of the hard drive just in case. Thanks for posting this news.

    Happend here for hundred computer of my office. For those who didn’t switch off pc, panda restored quarantined files after a while. For the ohers (I did), some cmd command in admin mode where necessary to cut panda services (see panda website for more details) , then executing the ps-recovery. Good as new, as moonlight said. But what a waste of time!

    For w7 users who switched off, … not good new because no solution founded yet without restoring all

    True, Panda Antivirus is not the first to break users’ machines, & neither will it be the last to do so.

    Perhaps we need insurance policies for the end-users of 3rd-party software, as well as Windows Updates. It appears that we are much more likely to have our machines badly bricked by program updates & installs than being run over by a car.

    Dec 2014: Bad Windows Update patch broke certain versions of Windows. Some users ended up having to reinstall the OS.

    May 2012: Paid versions of Avira Antivirus received an update that blocked almost all Windows EXE files & prevented the OS from rebooting.

    Apr 2010: A McAfee Antivirus update quarantined critical system files, terminated core services & made Windows unable to reboot.

    There’s not many anti virus programs, that white list window’s files, and that can be a pain later on, if the anti virus, starts removing windows files. I normally use Norton Internet Security, it’s a really good anti virus program, but it has it’s flaws to.
    Malware Anti malware, is the best to use if your computer is oinfected, but is not good enough to protect against virus.

    If it was up to me, i would have a program, that “Scans windows folders and index’s windows files, then it white list’s the windows files” and then protect the system. So there is no windows files that can be removed.

    it caused a massive problem for me as i am a university student with essays due in 6 days, and i couldnt save or do my work, with my files disappearing everywhere. Luckily i had a back up of my uni work and when i re-installed windows everything is fine. Do i keep panda on my pc or change, im not sure?
    Its now going to take me days to re-download all my games etc with student halls internet being so slow haha

  13. Get rid of it there are other anti virus programmes in the cloud

    Does anyone know if it is safe to restart now?

  15. Juan Figueroa

    The Antivirus is good, is not the only one that had encountered that issue in the past, it has been fixed now with a new virus definition.

  16. Juan Figueroa

    If you unistalled Panda and fixed the problem about the deleted system files you can install it again because it will use the most recent signature file.

    good to know. i ll have plenty of work for the next weeks 🙂

    We have had a huge problem as a result of this Panda update. None of the fixes worked (we had re-booted). Result? I’ve bought a new computer, re-installed the company’s accounting package along with everything else and taken the original computer back to nothing to start again. Lost days of time and much £. I now need another Antivirus – or is it safe to use Panda again? I’ve tried avast, and avg but both are causing the network drive to fail so I’ve had to get rid of them. Help please!

    Hi Did anyone answer this? I too need to know!

  20. DaGoldenBall

    Had this problem, myself used system restore to get rid of Panda antivirus. The stupid software moved a critical windows file into quarantine which stopped AV from working itself. I couldnt go into the AV program to restore the file from quarantine, so my only option was to use the windows system restore. Very disappointed in this software. Wont be using them again!

    So, I lost my Panda Antivirus program. Literally everything from the Panda Antivirus program disappeared. It doesn’t exist on my computer anymore, and I didn’t uninstall it or anything. Would this error with rebooting possibly be the reason why the Panda program disappeared???

    Panda just bricked my laptop last night.
    It will not boot in any mode, not even recovery mode.
    Fxxx You Panda.
