how do I get rid of that bug that underlines words and produces random links?

[DottyDot]

'cos it's happened again and I can't remember...

It underlines random words on websites and the underlined words are links to different websites.

V. annoying. I've run a Malware scan thingy but it's not got rid of it.

Thanks to whoever can help

Does this help?

Ooh thanks will take a look!
