I thought I would make a separate thread as way of an announcement to explain what happened where some users saw their virus software flagging TSP as having issues.
One of our add-on providers was comprised and we had a script called Coin Hive added to our site without our knowledge. Coin Hive is a legitimate script, which uses your CPU power to mine "bitcoins" which are a type of currency. Essentially, the script is using your computer power to process lots and lots of mathematical sums which can be converted into money.
Coin Hive is legitimate, but it was added behind our backs and therefore is malicious. Coin Hive isn't going to steal personal information, install software etc it's just using your processing power unbeknownst to you (and us).
We are in the process of removing the script from the site, and then the next stage will be finding out exactly how it was added to prevent it happening in the future.
Hope that helps to explain! Here is an interesting article:

In essence, instead of seeing banner adverts everywhere, a bitcoin miner would simply use a little of your computer's processing power to mine some bitcoins which would pay for things in place of advertising, so it's interesting to read up on!
