Can remove all malware from your domains and close security holes. Im use few malware scanners like ai-bolit, antidodo, malware detector and soft for find rootkits - chkrootkit and rkhunter. Viruses have no chances. Can find all kind of viruses such as viruses/backdoors/shells/spammers etc. Also can update software for actual versions. After works done, you will get full report. Thanks.
