How did "one" get changed to "Half-two"?

You need to run a full scan with Malwarebytes Anti-Malware. You were also asked if this is only in IE...no response. You were asked to try System Restore...no response. We can't help you much if you don't answer questions for us.

Thanks again to all of you on this. I don't know if the problem ever came up on IE; I use both IE and Firefox and I am pretty sure that once when I tried to get to some .../mathematics/... web site it failed. I did full scans with both Malwarebytes and Avast! and I contacted Malwarebytes. They said the site could be dangerous and recommended staying away from it so that's what I'm doing. Thanks again.

Just went to the site and had no problems.

Hey MacGyvr...I think the OP meant that Malwarebytes said the OP's original site where he got the problem from was dangerous. OP still hasn't stated the results of the Malwarebytes scan..like scan clear or what other results there may have been
