I got this pop up twice, at the first time I ignored the message and shutdown the laptop and then it was really dead and failed to restart, luckily it was under the warrantee and they had to change the hard desk which was damaged with no apparent reason. Hence , in the second time, I called the number and paid the money and they had remote access to clean it up ( as the they claim), I , then search the net for their company and realized that it was a scam, since then they were trying to call me back 10;s of times and I was blocking them and felt worried about my security. Kaspersky is not detecting any thing, is that a relief or my PC is still exposed?
