Look at this page which an innocent Google image search result led me to last night:
As well as a bogus scan with blinking displays and an imitation desktop window (displayed within the browser) — supposedly checking my computer for malware and viruses telling me the ‘alarming’ news that ‘Your computer is infected‘ the website also kept trying to download an unrequested .zip file with the wolf-in-sheep’s-clothing file name of ‘anti-malware.zip‘. (God knows what you’d unleash if you unzipped that file!)
Yeah, sure thing. Oh yeah, you really are the ‘Apple Security Center’ popping up unexpectedly after a Google image search with a web address like: http://69.50.201.182/files/e13c9c5[snip]a04e3bef3b8fc0ecb80699ab1.zip
Oh yeah, I believe you.
Dirty trick. Rotten scoundrels like this prey on the innocent and the naive.
Loathsome weasels.
