A virus connected to a spoof internet advertisement. When you click on the ad it infects your computer often telling you that you have a virus and asking you to purchase a program to get rid of it.
I keep getting a flashing icon telling me my computer is infected - which it isn't . It is really bugging me cos if I ignore it, it installs a program and then wants paying for it! I must have clicked on some maladware.
When a singer gets tense knowing that there is a high note coming up.
