64 bit Win 7 SP!, Avast (Free), Malwarebytes (Free) and Super Antispyware (Free)
Yesterday evening, about 10 pm, I went on-line to check my e-mails, then have a look at 'The Register' and then come here. As soon as I went to open a page on 'The Register' I got a pop-up from Avast saying it had stopped an infection, see image below. This repeated every page until I stopped and switched to Chrome to find the same behaviour and IE 11 decided it didn't want to start.
At this point I ran a quick scan with Avast, result clean, then S/Antispyware which found and deleted a few persistent cookies, then a Malwarebytes quick scan which came back clean and finished up by running JRT which said it had found a few problems in Chrome which it had fixed.
Following a re-boot I went back to 'The Register' to pick up where I had left off to find I was getting the same pop-up. At which point I shut down and re-booted into Linux where at least i am not getting the warning pop-up.
I must have taken this screenshot when I was in Chrome, but the one in Firefox except replacing 'Google' with 'Mozilla' and 'Chrome' with 'Firefox'.
My question is - have I a problem or, since everything is coming up clean, is this some kind of false positive ?
