We've nailed it down. A legit tool was backdoored and loads a malicious dll with zero detection at VT which loads the following encrypted payload:

I expect the detection to be available momentarily via streamed/pico updates.

Also please confirm that you have enabled the LiveGrid Feedback system for maximum protection.

LiveGrid Feedback system is active. Should I format to Windows 10? Will this problem take a long time to resolve? :)

You can scan the content of the folder that you supplied to me. If not detected yet, reboot the machine to enforce update of the LiveGrid blacklist.

I see the warning text has changed after restarting the computer. I scanned again and saw it deleted two spyware. You got him, Sir. The alert is no longer displayed. Thank you so much! :)

Looks like my suspicious were correct. It was a coin miner.

The question is was HashCalc actually and deliberately installed? Always opt for portable download versions of utility software like this.

-EDIT- Also think twice about installing or running directly any unsigned software which I assume this HashCalc software was.

I am absolutely not interested in mining. What are mining software? I do not know. I have never used it. There was no problem with CPU and GPU statistics. But the important thing is that problem has been solved. I am very grateful.

This was because Eset was blocking execution of it when loaded into memory. You're a lucky fellow on this incident.

Hackers usually target servers to drop a miner on to mine bitcoin. But, it does happen with client devices also.

I suppose the question is have you downloaded or installed anything new recently or opened any email attachments that may have been malware

For example this for Bitcoin :

Quote

By mining, you can earn cryptocurrency without having to put down money for it. Bitcoin miners receive Bitcoin as a reward for completing "blocks" of verified transactions which are added to the blockchain.

Malicious software programmers will program miners and spread it to many devices over the internet so they can mine cryptocurrency for themselves on your device , saving themselves the costs of hardware and electricity , now it doesn't look any helpful because still it's 1 device and possibly be weak and not strong

But they aim to infect much larger numbers so they can benefit from it.

So by making a miner , instead of mining on your own 1 PC or buying several devices/GPUs for mining , they go ahead and infect thousands of devices so they can mine fast and without costs.

If it has kicked in and worked like it should , it should utilize most of your CPU/GPU or both and probably your PC will be tired after a good amount of time this has been running.
