A pop up for downloading adobe flash update appeared, started to download and it asked for $9.95 to finish download. We did not finish download. Then a blue screen appeared in Safari window asking us to call a number because our system was attacked
A pop up for downloading adobe flash update appeared. Started download and quit when it requested a payment of $9.95. Then the Safari page turned blue with a security warning and a voice came over the speaker telling me to call a phone number. When you call they want to take control of your computer to fix the problem. This sounds like a scam so I hung up. Wondering if it is possible that my security is compromised by starting to download this so called update.
