Action Summary -- Quarantined Viruses what >> mean in file/ entry

Hello

There is one thing I don't understand in Action summary in SEPM . In File/Entry tab there are those ">>" characters . i.e C:\Users\SymantecAdmin\Desktop\File_name.msg>>__subhgfg1.8_888888>>urgent 888888.js

Console report this file in quarantine list and there are 4 entry of the same file but with this >>. What does it mean ?
