    HELP "Need permission from SYSTEM to change this file."


    So My computer has been acting up. I downloaded a "free" antivirus that turned out to be a virus. It just slows my computer up and hasn't fried anything yet, However i was able to download AVG and stop any major issues from occurring. Now I am trying to delete said "free" antivirus, yet i keep getting this message. "Need permission from SYSTEM to make any changes to this file." I have no idea what that means especially considering I am the SYSTEM as far as I am concerned with this computer. Somehow my firewall and antivirus had been disabled months ago and I know I didn't do it. This was a couple of weeks ago. Since then, I have been fighting to keep my computer alive. Please help me figure out how to have my like new laptop.

    Try kaspersky TDSSKILLER

    TDSSKiller Rootkit Removal Utility Free Download | Kaspersky Lab US

    Malwarebytes has one too, they are both pretty good. If it is a rootkit, you can remove it all by running the rootkit killer and you wont have to run a full antivirus scan. Many viruses and rootkits evade programs like mcafee and norton, and I think even Windows Defender more effective than those, use Windows Defender to check for any main virus bodies, but run TDSSkiller to check for rootkits.

    Joe,
    use another pc to download Microsoft offline security scanner(its free) burn it to cd or save it to a bootable usb flash drive, then put it in your new laptop and boot to it by using the boot option on power up screen and follow directions. have used this to beat several nasties for friends.
    Good luck, but have patience ; at worst you can reinstall your operating system
