I was looking for a file I had lost, but in the search Twunk_32 came up. I found what I had been looking for, but was curious as to what Twunk_32 actually was. After Googling I was confused as some sites said it was an undesirable, others said not so. I'll be back in a few mins, as I'm scanning with Superantispyware.
You were both right, all scans are coming up clean, Superantispyware came up with only a few cookies, and Avast is finding nothing. I've had another look at the file and have been able to identify the company its related too. (Wouldn't show me yesterday), but yes, you guessed it, its HP. Sorry for asking the question, but I had to know, as I was worried one of the kids had downloaded a bug again.
But I guess it is to do with the scanning capabilities of my All in One. (Big Sigh!)
I'm resolved so will tick, thanks to both of you, and all else who replied.
