Registry errors and High CPU usage

[Cassie72]

 ::)Hi everyone, I`m new on here and having problems undrestanding certain messages that pop up onscreen!
1)  What are registry errors?  I keep getting a message that says I have 102 registry errors and inviting me toget them dealt with.  When I click on I see that it will cost me an amunt of money and am not sure so I close it down.
2) I keep getting a message showing me a graph and saying there is high CPU usage.
  This is from Internet Explorer.  No information about solving the problem whatever it means.  I`m really green, not at all technical, but these messages that keep displaying onscreen worry me!   Any advice please?

First, ignore the messages and do not buy anything or try to repair "registry errors" - there are none. Second, it may be malware - let's find out.
