I have SCCM server. SCCM server detects the virus Ransom:Win32/WannaCrypt.A!rsm for windows 7 pcs. But it can not completely delete that virus. After scanning those PCs with SCCM server, it detects that virus. But after someday it come back to those pcs. Around 1421 pcs of windows 7 are affected with that virus. Our whole system are in vulnerable condition. Is there any way to remove Ransom:Win32/WannaCrypt.A!rsm Virus Completely from Windows 7 PCs?
