Unwanted intrusion

For about a week we had some uninvited software on the KvsCC website. After loading a page, the next click to look at a different page caused a new window to open with an advert for easy money or in the case that finally caught my attention, a voice that told me that it was a Windows message to say there was a lot of bad stuff on my computer and clicking a button on the page would deep clean it away. I hope this did not put off regular readers of KvsCC, and I have now eliminated the source of the problem since the 21st June. Never respond to any pop-up pages. If you are unsure what to do then shutdown your computer to clear the message.
