    Anything left before I have to reinstall windows?

    So I'm actually on a fresh install of windows, bought a new machine with it pre-installed a month ago.

    Yes I torrent. But I've been using PCs since the 90s. I know what to click on and what not to (at least I think).

    I've tried most things on this page

    I've looked through the registry, nothing. I don't have other AVs installed. I downloaded Malware Bytes and it found 42 threats but quarantined them all.

    I searched the registry and nothing looks amiss.

    I tried running System File Checker and it said: Windows Resource Protection did not find any integrity violations

    I don't get it. Do I need to install an AV temporarily get at a potential virus. I really don't want to re-install Windows, this is so ffd.

    Task to auto update windows defender definitions disappears

    My mom has a new laptop with windows 8.1, we always set the windows updates to manual.
    On our other windows 8.1 computers I have created a task for auto updating windows defender definitions, which works fine for us.

    This is how I created this task:

    "Click on "Create Task", name it what you like (mine is Daily Signature Update), set the trigger as the time you want it to run every day.

    For Action browse to Program Files\Windows Defender\MpCmdRun.exe and select it. In "Add arguments" add -SignatureUpdate -MMPC"

    But somehow this task disappears once it has run on my mom's laptop.
    I'm logged in as admin and then I also tried it with running the task scheduler as admin, the task just disappears every day for some reason, while it works fine on our other windows 8.1 computers.

    Anyone an idea why this task disappears every time?

    Thanks.

    My Windows Defender disappeared and I've tried everything on Google.

    Browser hijack? GPU 15% when using google in FF

    So as the title suggests I have an issue with FF when I perform a search from the address bar (google is default) or even going directly to www.google.co.uk, my GPU usage goes from 0 to 15%, it stops if I close that tab or change to another or bring another window to the forefront but it consistently displays this same behaviour.

    So I have tried the following to try and find out if there is some kind of malware/hijacker going on.
    • Uninstalled FF and reinstalled.
    • Installed no miner, miner blocker, ublock origin and adblock plus extensions.
    • Run numerous scans of Windows defender, avast AV and MBAM
    All of the above to no avail and every time I am on a google page the GPU useage stays at a constant 15% and the vRAM usage inscreases. Scratching my head is there anything I am missing?
