Blocking of bbs.vbstreets.ru forum

Why site http://bbs.vbstreets.ru/ is treated as dangerous and blocked by Avast? I’m almost shure that it’s not. I’m registered at that forum for a long time and it’s a very good prograaminng forum and it has a good rating. Also I’ve checked it now via DrWeb online tool ant it shows that site is clean. What happend?

I did not find anything apparent.
