I have faced the problem in my company that sality virus regenerating inside after detecting and cleaning. Currently we are using Symantec Endpoint Protection. But the virus spreading over the network and immediately disables the Symantec Antivirus and also I have tried to clean using lots of tools like rmsality, sality killer, combofix, dr.web, rescue disc, even many antivirus like Kaspersky, McAfee, Symantec, AVG, etc. nothing can detect this main virus, its detect something but regenerating itself. Kindly give me a solution. Thank you for your extreme help.
