osi.od.ua - banners are spreading malware

The other day osi.od.ua came up with a proposal to place a banner.
Installed, now Yandex in the extradition writes "The site may threaten the security of your computer."
The webmasters section on Yandex confirms that an unsafe code was found on those pages where the banner was placed.
We are not the first, familiar webmasters confirm the situation with banners.
They give money weekly, they ask for two days of dough, they demand a frame.
Apparently so trojans spread.
ICQ, which is addressed: 483-040-098.
Just in case, be careful.
