We were recently informed by some people that apparently the Avira anti-virus protection shows an alert on MS Internet Explorer 7 for this blog "HTML/Infected.WebPage.Gen.", which is a trojan around since last fall (damage potential: low). This alert which seems to appear since 2-3 weeks is not reproducible neither with Symantec, nor Trend-Micro on neither MS Internet Explorer nor Firefox. Some googling brought up that others have reported the same problem for blogs on blogger or wordpress.
I suspect this is a bug with the virus protection, not with this website, and that it wrongly interprets part of the html code. I haven't changed anything about template (e.g. add-ons) for several months, and the rest of the website is generated by a blogger-script that runs for everybody on blogspot. There also aren't any trackbacks which show up on the entry site, so that can't be a cause either (in some forum you'll find a recommendation to delete all trackbacks, but it doesn't sound plausible to me).
Another bloggy thing: Stefan and I, we had to notice that the 'publish' button under the comment preview presently doesn't work. Again this is a script we have no influence on, so we can't do anything about it. Please use instead the 'publish' button under the word-verification which seems to work just fine. If you use the wrong button and notice your comment doesn't appear (there is no error message), scroll up - the comment isn't lost unless you leave the site, it just stays in the textbox.
