    Manual Virus Removal Tool

    Manual Virus Removal Tool

    MVRT is a small utility to unhide all files and help in virus deletion

    Manual Virus Removal Tool 1.01-beta Platform: Windows ============ Information: ============ 1- This is NOT an Anti-Virus so don't assume it to be one. 2- If you don't know anything about file types specially (.exe/.bat/.vbs etc) then this application is useless for you. =========================== What this application does? =========================== You select a folder, click 'Unhide All' and MVRT unhides all the files and folders (even super hidden ones) inside the chosen folder. Then you can either go to that folder in the Windows Explorer and delete the .exe,.bat,.cmd,.vbs files or shortcuts you suspect to be viruses. Or you may choose the file in MVRT itself and click 'Delete File' to delete it. You can also check basic information about files like attributes and file size by choosing a file from tree and clicking "File Info". ==================================

    Windows Defender Central v0.5

    Windows Defender Central v0.5

    Windows Defender Central

    A very basic centralized management for Windows Defenders. It is in BETA state, but it is usable. It works only with Windows 10 Defenders. Updated the code: it is now compatible with build 2004 and it uses multithreading to query the machines. It uses PowerShell and SysInternalsSuite(PsExec.exe) to gather the information and it stores the data in a shared network drive (what the computers can access and have write access). It can store the data locally, if needed. What are the "computer name" background colors? -White: idle -Green: querying state -Pink: any other action besides querying -Red: one or more protections are disabled It can't show color on the highlighted row... What is planned? -to see the quarantine -delete from quarantine -whitelist from quarantine What else?
