ok so after all that i did another Avast Boot Scan and it detected 2 files

C:\WINDOWS\ikuracjg.old infected by Win32:Agent-PSI (Rtk)
moved to chest

C:\WINDOWS\System32\drivers\cjphnmli.dat infected by Win32:Agent-NGL (trj)
moved to chest

the file C:\WINDOWS\System32\datacle.dll is still present in the folder, but Avast no longer detects it as being infected. Good news???
