Hey there,
I am really sorry for the delay of this reply as it is a weekend for us here.
It is possible to remove that, but we need to take a look of your current menu structure, I suspect your existing menu item alias have called Easyblog.
If you already double check there do not have any menu item call Easyblog, then I suspect you have install those 3rd party SEF extension e.g. Sh404sef, then you need to purge the SEF URLs first then let it regenerate those SEF URL on the site.
If you didn't install any 3rd party SEF extension, perhaps you can update your site backend and FTP access at
