Copy n Paste problem

where are you trying to paste it into??
if you are using word you might want to check for any macros that are executed when you press Ctrl+V or paste. If it's happening in any app then you probably have a virus. A Virus seems the most likely cause for this issue anyway.

Update your antivirus software n go for a complete scan.

If you are in an urge,Try to save the webpage as *.mht. so that u can do the research of copy n paste later.
