Dllhost.exe still persist in task manager, taking up cpu memory

[Zypher]

Hi I'm new and I seriously need help I'm at my wits end, I tried everything and nothing works. Tried malware bytes, hitman, rouge killer, clean boot, went into safe mode. Changed codecs for the thumbnails. Nothing works.

The dllhost.exe virus still persist. A temporary fix I found was disabling the network adapter and the virus stops replicating in the task manager, but as soon as I turn it back on the virus starts replicating and takes up cpu memory

I'm think of backing up my data and do a clean install to get rid of the stress.

it can take weeks to clean a virus and even then you can never be 100% it's gone completely and it's a lot quicker to reinstall Windows if you can so back up your data and use the below tutorial to reinstall and it's good for retail also

One last question. If I backup my files using an online backup service like OneDrive. And then reinstall windows will I lose my backups there?

You won't lose your backup on OneDrive or other online services but I also suggest to make a backup to an external hard drive and disconnect it from the computer once it's done. If you do intend to reinstall windows use the below tutorial for a better experience
