I am seeing malware in the "severe" category being detected every day. WD says it quarantined them but they keep showing up daily. Right now as I am typing this I have seen 3 detections of Nemucod (by Windows Defenders' naming).

 

Also experiencing long periods of excessive HD activity and unresponsiveness for no apparent reason, sometimes have to power off to stop it.

 

The trojans reported by Windows Defender over the past few days include:

 

TrojanDownloader:JS/Nemucod

TrojanDownloader:JS/Swabfex.P

TrojanDownloader:JS/Ransdown

TrojanDownloader:JS/Donvibs.F

 

OS is Windows 10 Pro

Use the programs below to clean, remove malware and remove adware.

 

Use CCleaner to remove Temporary files, program caches, cookies, logs, etc. Use the Default settings. No need to use the

Registry Cleaning Tool...risky. Pay close attention while installing and UNcheck offers of Google Chrome and Avast.

After install, open CCleaner and run by clicking on the Run Cleaner button in the bottom right corner.

What about the other scans? Need to see results of both Malwarebytes scans and Eset before offering further comments....
