Okay, so i would be very security conscientious at the most part but just recently i downloaded several miners, all linked to from these forums, for different crypto-currencies as a means of testing.
Having read someone who was asked to run a Java program randomly which proceeded to run an exploit to enable the hacker to remove his funds (cant recall the topic but it's here somewhere) i was fortunately prepared when i was asked to execute a very suspicious 'Java Upgrade' less than 10 minutes ago.
I'm now doing a full run of Anti Malware / Anti Virus searches and removing all the mining software i downloaded.
I am posting this to ask everyone to be very careful when downloading miners as i'm as certain as i could be that this was a virus (Java update was not from Oracle, some random address) and i'm sure i got it from the Miner software i downloaded as there is no other avenue it could have came from.
Be careful and stay safe!
