I’m just looking a google images of he avast popups and I’m wondering whether one of them at least didn’t say ‘infection detected’…
However as I said nothing came up in the scan but the three urls were in the history of the web shield.

Confused and very worried.
The more I read online… (a bit like googling illness) the more I become worried…
There has, however, been no strange activity from either my computer or my twitter account since the clicking incident this afternoon.
