|We can do a malware scan, but not sure we will be able to recover the files...|
Try the following:
Download Malwarebytes' Anti-Malware (MBAM):
Save the program to the Desktop
On the Desktop, double-click mbam-setup.exe to install the program, and follow the prompts
If an update is found, MBAM will download and install the latest.
At the main program window
Make sure the following is checked: Perform Quick Scan
Click: Scan (The scan may take some time to finish, so please be patient.)
When the scan completes, a message box appears, click OK
At the main Scanner screen:
Click on: Show Results
A screen displaying the malware found shows
Make sure everything found is checked, and click: Remove Selected
When the disinfection is complete, you may be prompted to Restart the computer. Please do so.
When MBAM finishes removing malware, a log opens in Notepad
The log is automatically saved and can be viewed by clicking the Logs tab.
Please provide the contents of the MBAM log in your reply to see where we are at..
