    Antivirus: Windows Defender, Disabled

    Please help me if you can..........
    Something disabled Windows Defender and is letting very large bogus files onto my computer so I installed the latest free version of Avast. I am using win 8.1 in a Lenovo computer. I just discovered that some mystery files are being inserted into my computer by the dozens and these mystery files are extremely large so the hard drive was almost filled up!
    Here is what I found by using an app called WinDirStat:
    the mystery files look like this: 12754694899610736661_2853498758043839360_4480_4480 ~ 960 MB
    and this: ver1
    they are sent to this location in my computer: C:\$Recycle.Bin\S-1-5-21-2712117882-3860235528-2112810399-1002

    When I open the mystery file with FIREFOX, it looks like this:
    which is an application/octet-stream (960 MB) from C:\recyclebin

    Note: file opens in Firefox but there is no information in the page and, after selecting Ctl - U, there is NO code at all!

    These files are still coming into my computer after installing Avast so PLEASE help me if you can. I can catch these files with the help of WinDirStat but want to stop them altogether. I believe a virus has invaded my PC and had hoped that Avast would catch and kill it but not so far!

    Hello jim rich,

    Please download Farbar Recovery Scan Tool from here and save it to your desktop.

    Note: You need to run the version compatible with your system. If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.

    • Right click to run as administrator. When the tool opens click Yes to disclaimer.
    • Press Scan button.
    • It will produce a log called (FRST.txt) in the same directory the tool is run from.
    • Please copy and paste log back here.
    • The first time the tool is run, it makes also another log (Addition.txt). Please also paste that into your reply.
