Firstly, sometimes when I copy a line of text in a web page so I can use it elsewhere I get a drop down box telling me I have copied something and it could be malicious, however the box disappears so fast it is hard to read it all and digest what it says (I think it comes from Malware bytes but there is so little time to read it before it disappears) so don't ask me to copy it so you can see it, can I some how get it to stay there so I can understand it.
Secondly, about the same time as the above problem started I have found that when I highlight a line of text and do a right hand click so I can get a drop down menu so I can copy it to clip board that option is not available to me this is most annoying, my guess is that Malware bytes is blocking that action.
