What is your computer make and model? Which operating system are you using? Have you scanned for malware? If not, please try the steps in the link below:
If no malware is found after performing all the scans, (it will take a while to perform them), then try using the free "Unlocker" program from the link below to unlock the file, then allow you to delete it.
You might also try restarting into Safe Mode and manually delete the file from there.
Hope this helps.
I go to setting set pages but it won't allow me to delete http://www.22find.com/?utm_source=b&utm_medium=mlv&from=mlv&uid=ST3750528AS_9VP9FV9MXXXX9VP9FV9M&ts=1363929177
