No, the problem is not in any way related to malware/virus infection.
Disk file-system corruption sometimes happens, most often when the computer is shut down improperly (for example by using the pwoer OFF button instead of the proper shutdown procedure) and quite often when the hard drive starts developing bad sectors.
Assuming your computer has loaded Windows successfully, let's run chkdsk /r again, and get a look at any recent logs.
- Please post all recent logs that you can find.
Use the Windows Error Checking
utility (Check Disk), with the options to fix file system errors and scan the disk surface for errors, attempt recovery of data and repair the disk.
A log of the disk check is recorded only if the scheduled re-start is used, and only for drives on the same HDD as the Operating System.
- Open "My Computer"
- Right-click on the drive that you wish to check > Properties > Tools > and in the "Error checking" section, click on "Check now".
- Place a tick in both boxes > Start.
- If the disk you have chosen is the system disk:
- A message will notify you that a restart is necessary: Click OK, and close all windows.
- Re-start the computer. The disk will be checked when the system boots.
This test will take some time to run and at times may appear stalled but just let it run.
- When the disk check is complete, the system will re-start automatically and load Windows.
To open Event Viewer
and view the log:
- Go to Start > Run > and type eventvwr and press the <ENTER> key.
The Event Viewer window will open.
- In the left pane, click on Application.
- In the right pane, at the top, click on the column heading Source to sort the list alphabetically.
- Look in the Source column for "Winlogon", with an entry corresponding to the date and time of the disk check.
- Double-click on that entry to view the log.
- Click on the button to copy the log text to the clipboard.
- Paste the log text into your next reply.
