I know that VK,com code is OK as it is, still it is exploitale via a SQL attack.
The OVERDUE malware that is detected at your site is Andr.Exploit.Rat → http://support.clean-mx.de/clean-mx/viruses.php?id=31224650
See:

Whenever that is a FP, report virus@avast.com and mention this link https://forum.avast.com/index.php?action=post;topic=163923.0;last_msg=1168394
Also I do not know the reason why the good guys z Petersburgu (DrWeb’s) added your website to their list of malicious sites.
Maybe it had to do with this detection: https://www.virustotal.com/nl/file/c5c99eba741eb1c84ead856510e5e7bb721bd1da197dbf2f64e247d08e20ff9b/analysis/

Malware can come through advertisements and admitad is not a trustful site when it comes to delivering adds.

If you look at the links we provided, you will see that your website has multiple issues.

Well Alexa states that admitad is unsafe. At least given as suspicious: http://www.scamaudit.com/domain/admitad-lounge.ru
