There doesn't appear to be anything malicious in QuickWit's post itself. It's possible one of the banners at the top or bottom of the page tried to do something it shouldn't have.
Can you tell me what the error message says, or post a screenshot of it? Did it only happen the one time or does it happen every time you load that page?
Hello StoneTable,
I think you could be onto something there, about a banner doing something.
The message said, that a threat was detected and than it showed where it was located. I should have written the next bit down, but it said the type of trojan or virus it was related to. It did not however say the cause for it. I closed it, without doing anything as it was just hanging on my desktop. I couldn't clean it or delete it, as it said there was an error each time. I hope this helps in someway.
The page seems to load fine since then, and no trouble of anything neither.
I just went and searched for the file or the log that caused this, in ESET but can't find anything. The only mention of it, is on the front page where it says
number of blocked attacks - 2. (These two - which happened today, I went back to QuickWit's page to see if it would do it again, and it did. In the end I discarded the threat, as the threat pop up wouldn't go away)
