Found this string on my wife's computer on my last virus sweep:
C:\Users\Meme\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\28\2e002d9c-6c2ebeb3|>com\bitcoinplus\applet\MiningApplet.class is infected by Java:Bitcoin-A[Trj]   

My wife has never even heard of bitcoin. Any possibility that someone tried to use her computer remotely for mining?

Mining very PC these days is very unprofitable, you barely can make a cent in a month. I think it's outdated malware created to mine bitcoin or malware created to steal user's bitcoin.
But, i think you better focus on delete/remove that malware instead thinking the reason/purpose of that malware Roll Eyes

There are several different pieces of malware that are designed to hijack people's computer in order to mine Bitcoin. It is very likely that the virus is such a miner, although I have never heard of one written in Java. Either way, you should still have your antivirus remove it.

You could check out this --> https://forum.avast.com/index.php?topic=101341.0 and also http://runescape.salmoneus.net/forums/topic/362822-how-did-i-get-hacked/

People are still using CPU's to mine Alt coins, so even if it is not Bitcoin, it might be some malware that was installed to use your wife

computer as part of a bot network.  Angry .... What AV software is she using?

Doesn't even seem to be partly worth it on the side of the hacker to go ahead and use someones computer to mine, ASIC's have taken over and it wouldn't make him enough money to cover the time spent to even hack into your wipes computer.

Though, I guess some people are desperate and still do this. Could have actually happend or maybe a false positive from something that you downloaded so you may want to check on your most recent downloads on that computer.

This is the first time i heard about this kind of virus or malware. But it doesn't make any sense to me. Hacking someone's computer just to do mining. Anyway, its still a virus that should be deleted. You're still lucky tho. You haven't lost any important infos. In your wife's computer. Good thing you have an antivirus that blocks virus on your wife's pc.

Good thing you wife does not know bitcoin or else shes a goner. Nothing is safe from those miner they would steal every bitcoin they find. This is why I don't keep that much and always deposit it to some casino making them my bank.

Just because the file has bitcoin in its name, it does not really have to do anything with it.
But I have noticed that the malware is located in the java folder.
Personally I would say that it's not wise to let java store any kind of files on a computer (there is even the question if she needs java at all).
I would really change the settings in the java controle panel so that it does not store any temporary files on the computer anymore, deactivate java in the browser content and empty the cache folder as well.

Possibly thats a virus that will steal your bitcoins in your wallet. You are just lucky since your wife doesnt have bitcoin otherwise they will harvest your bitcoins. The most trending virus that is occurring to computer of bitcoin users is the bitcoin wallet address virus.  When you copy your wallet address and the moment you paste it another address will appear. And if you dont crosscheck the address then it will go to the hackers bitcoin wallet.

I recommend you to disable Java on your browser if you don't need it.

Anyway, its still a virus that should be deleted. You're still lucky tho. You haven't lost any important infos. In your wife's computer.

This is not new, someone else's hardware is much cheaper than mining with the best ASIC hardware and the cheapest energy ever.

Definitely disable Java in the browser. If you don't use Java for anything on the PC, I'd even recommend removing it entirely. At the very least, you should ensure that Java is completely up to date. Java has had a ton of security issues so if it is outdated, there is more potential for exploitation.
