Restoring Hidden Or Unreadable Files

How to Remove Viruses From Your Computer

Some viruses can modify files to make them unreadable. You might need to take extra steps to recover your files. If your files are blank or look like shortcuts, they are probably just hidden. Launch the command prompt, then browse to the location where the files are stored. Type the following command to restore your files: attrib *.* -h -s /s /d then hit Enter on your keyboard.

Disconnect From The Internet

Now that you have your weapon, its time to cut the connection, so the malware cant use it to share your data or send itself to all of your contacts. Turn on Airplane Mode, switch off Wi-Fi connectivity, or unplug the internet cable, and youre done. If the virus is blocking control of those functions, and your connection is wireless, turn off your cable modem or router.

    Get Rid Of The Malware

    I am using Malwarebytes for this example. You can use another application that accomplishes the same thing, but it is the one I am most familiar with. You can download the application from the link below and install it. You must reconnect to the Internet for this. Once the download is complete, disconnect from the Internet again. If you cannot access the Internet, or you cannot download Malwarebytes on your computer? Download it on another computer and save it to a USB flash drive or CD/DVD and transfer it to the infected computer.

  • Run through the setup and follow the installshield wizard. Malwarebytes checks for updates and then launches the user interface .

  • NoteYes to download the updates,OK

    Keep the default scan option – Perform quick scan and click the Scan button.

    The application offers a full-scan option, but I recommend that you perform the quick scan first. Depending on your computers specifications, the quick scan can take anywhere from 5 to 20 minutes. However, the full scan takes up to 60 minutes or more. You can see how many files or objects the software has already scanned. It shows how many of those files that it has identified either as being malware or infected by malware.

    Removing A Virus From A Windows Computer

    In Windows computers, the virus removal process begins by booting up the computer in Safe mode. In this mode, your computer starts with only essential programs running. This prevents a viral program from starting up and blocking your antiviral scans. In older versions of Windows, you can access this mode by pressing the F8 button during the startup process.

    In Windows 10, the process of opening in Safe mode is slightly more involved:

  • Press the Windows button and click on Settings.
  • Go to Update & Security and choose Recovery.
  • Choose Restart Now under Advanced Startup.Your system will restart, but a new option screen will appear.
  • Choose Troubleshoot.
  • Go to Advanced Options and choose Startup Settings.
  • Choose Enable Safe Mode.
  • Once your system restarts in safe mode, you will be able to run an on-demand viral scan. Because the number of viruses is always increasing, you may find it helpful to run several different scanning programs to catch any newer virus. It is important to use antiviral programs from reputable vendors so that you do not make the problem worse.

    You should also follow these best practices:

    Backup your critical data Clean up temporary files and cached content Uninstall any/all applications no longer in use Update OS and remaining applications Check startup apps, disable unneeded apps Run the MMC Run a full Scan of the system

    Obtaining Windows Security Updates

    If you do not have a broadband connection that is always on or you want to check for updates, you can manually check for and install security updates for Windows Security.

    Virus, spyware, and other malware definitions are files that Windows Security uses to identify threats to your computer. Microsoft regularly provides critical updates to make Windows more secure. These updates are important for protecting a computer. To keep these definitions up to date, Windows Security works with Windows Update to automatically install new definitions as they are released. If you have a broadband connection that is always on, set the Windows Update tool to automatically check for updates daily.
