2 Strange folders

[SoheilY]

Hi all

I have 2 strange folders in my 2 servers (Host root directories). I want to know that if they are not important so I could delete them because they are over 70GB.

Address:

Server 1: D:\inetpub\default\6334\localuser
Server 2: D:\ErnaHostServer\default\15349\localuser

they are a copy of all my hosts with some other files which are infected.

COULD ANYBODY HELP ME ?????

Thanks with best regards
