We all know that there are BTC trojan miners, which mine BTC in your computer. But how to detect this trojan ? If I understand right, you can not see this through the task manager. So you must check your CPU speed ? And the main question - how to delete this parasite ?

On windows there is anti-virus and anti-malware software. This software may detect this trojan.
Alternative is boot from a live disc, which is usually another operating system. This prevents a trojan from getting on your hard disk in the first place.

That's what the Antivirus is good for. to detect potential threats! If you have a good antivirus and keep it updated it will protect you from that kind of harm.

And if you know you have one I would blow OS away and reinstall.  I don't trust it's gone if I knew I had something.  Might sound extreme to some but it's really not that hard to do.

If you do this then make sure to get current updates, anti-virus, anti-malware, etc.  After you get all that back up then stay away from whatever got you the trojan in first place.

Not all antiviruses or in fact, no antiviruses can detect every threat in the world. It is not easy to check for such a virus. Some virus are only programmed to mine if the computer is inactive for X minute or when the task manager is not open.

A good example is looking at botnet's.  Sadly a "bad guy" could have a ton of computers in his botnet.  He chances are sells it to highest paying person as it truly is a criminal enterprise.  I mean if your computer is infected with something where they control it like a  botnet your computer can be doing some very bad things.

You could be doing anything from sending spam, attacking websites, to yes mining.   And you could change depending on who is paying botnet owner. 

I agree not all get detected.  You might get lucky and get them all but quite possibly part is left.  Honestly if you have one or had one blow away system and restart. (Make sure if you had a hot wallet to get private key or wallet file, and honestly don't keep much in any hot wallet).

Use a good premium (not free) version of Antivirus + Antimalware and install them right after you install the OS and get them updated, I use Avast + Malwarebytes Anti-Malware and they both provide real time protection and stop any such programs from entering the computer.

Here's a guide if you suspect that something of that sort is running on your computer: http://www.malwareremovalguides.info/trojan-bitcoinminer-removal-guide/

Apart from using Antivirus and Antimalware it also uses  HitmanPro and RogueKiller.

There are some free ones that are not to bad I would say.  Granted it varies greatly depending on which ones were talking about.  Avast really has grown in userbase over past years.   

I would agree with Malwarebytes being a very good layer to have in addition to have.  I would suggest having multiple layers.  One thing I would also suggest is keeping router current and having a firewall on it.  It gives you a layer before something can hit your network (hopefully).

i have this setup for now, hitmanpro+malwarebytes+zemana, i'm satisfied they catch almost everything and i'm secure enough

any antivirus was slowing down too much my pc and was not really needed, i remember with avira, it even let one virus pass...

I prefer avira+malwarebytes - whatever you do, get malwarebytes. also, make sure to keep windows up to date.

I am using this as well, since awhile and it works quite well for me.

I would just like to add that I am very careful in what sites I am visiting and also at the smallest suspicion I just go ahead and reformat my computer. With all of this above, I never had a single problem!

You can use any anti virus to scan for it. In most cases, the software is able to detect them ;D if you want to be sure that there's none left on your PC, try format the whole drive ;D

My question is: would it be worth designing a Trojan that will mine BTC with a CPU?  In order for this to be worth it, you would have to have over 10,000 computers working just to bring in 1 BTC per year.  That hardly seems worth even designing the virus.  Once it has been found, someone will update virus scans and take care of it before you would earn anything.  Does this make sense to anyone or am I barking up the wrong tree?

No it's not worth it for 1 computer (unless that computer had sensative info and they are getting info off it).  A lot of these go into a botnet.  So they will do what ever highest paying person asks most likely.

I think of botnets as a owner rent's them out to people for cash.  And there is a lot of scary things they could be doing you don't want to be a part of.  So really make sure your protected from virus type applications.

Actually the computer got infected can be used in many purposes especially DDOS. And that service can make more than just 1 BTC a year ;D

I can hear the fans when i am on this forum.. ;D
