So you've probably heard of Unlocker and used/or are using it but recently I stumbled across another similar tool called LockHunter.
Ok it's been around a while but we all find things that have already existed for a time and decide to give it a go, so here's the sp.
LockHunter is a foolproof file unlocker It is a free tool to delete files blocked by something you do not know. LockHunter is useful for fighting against malware, and other programs that are blocking files without a reason. Unlike other similar tools it deletes files into the recycle bin so you may restore them if deleted by mistake.
It is available as a 32bit and 64bit application and has (as yet) No Bundling.
