Registry Editing::Manual Trojan Deleting

[OS]

My little brother tends to download anything that appeals top him (he is not very Internet savvy). Because of this, I have two new Antimalware programs that both say there are High rated threats in my Registry! I checked out the Reg. and discovered that the paths given to me lead to real files, and a few of them were bad. But I need to know if it is Okay to delete them? The latest High risk threat is a Trojan [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\SharedTaskScheduler] with a value of {8d8c2387-7f80-4022-9be6-43630a969558}

I remember that the value above is the same as the first Trojan I deleted, but it seemed a bit more harmless in it's other location. Is it safe to delete this one? Or should I change its value to something else?

Please Help, and Peace Out!
