Think moms computer is infected not sure

[fivealive]

So on Wednesday avast came up saying it found 45 files labeled rootkit:hidden file. avast couldn't remove them and when I contacted avast they said it wasn't a false positive(personally I think the guy on the phone was wrong), So I formatted the computer, well the computer is saying it has another infection same label rootkit:hidden file,

the file in question is labeled

C:\Windows\SoftwareDistribution\DataStore\logs\tmp.edb

Of note both Wednesday and Thursday(after the format and reinstall) Windows was running updates. On thrusday I though I had all the updates installed but apparently I was wrong since even today their was updates being installed.

The 45 files found on Wednesday where on SoftwareDistribution folder as well.

The detection by avast! is a false-positive, and your FRST logs are clean. Unless you are experiencing any other issues, there is no reason to suspect your machine is infected. 

 

However, we can run the following scans to double-check.
 
STEP 1
 Malwarebytes Anti-Malware (MBAM)

• Open Malwarebytes Anti-Malware and click Update Now.
• Once updated, click the Settings tab and tick Scan for rootkits.
• Click the Scan tab, ensure Threat Scan is checked and click Scan Now.
• Note: You may see the following message, "Could not load DDA driver". Click Yes, allow your PC to reboot and continue afterwards. 
• If threats are detected, click the Apply Actions button. You will now be prompted to reboot. Click Yes.
• Upon completion of the scan (or after the reboot), click the History tab.
• Click Application Logs and double-click the Scan Log.
• Click Copy to Clipboard and paste the log in your next reply.
   

STEP 2
 TDSSKiller Scan

• Please download TDSSKiller and save the file to your Desktop.
• Right-Click TDSSKiller.exe and select  Run as administrator to run the programme.
• Click Change parameters. Place a checkmark next to Detect TDLFS file system and Verify file digital signatures.
• ​Click Start Scan. Do not use the computer during the scan.
• If objects are found, change the action to skip.
• Click Continue and close the window.
• A log will be created and saved to the root directory (usually C:\). Copy the contents of the log and paste in your next reply.
