exchange.shikbraves.org doesn't appear to have any malware on it.
avast does not say there is ....... URL:Mal means URL or IP is blacklisted for whatever reason, there can be many, it does not have to be infected
virustotal does not scan the site for malware, it check URL aginst blacklists
killmalware and Sucuri say clean, and IP seems not Blacklisted
