Can't change homepage

I recently had a problem with "www.searching.net" being set as my homepage. So, I ran HijackThis and fixed it. However, now my homepage is set to about:blank and I don't know how to change it. Here's the log:

First, move hijackthis to a permanent folder like C:\Program files\Hijackthis\hijackthis.exe
Running it from a temp folder means you will loose backup and restore options on reboot or if temp files are emptied.

Second you have a trojan\
O4 - HKLM\..\Run: [Win Server Updt] C:\WINDOWS\wupdt.exe

Use starter or task manager to kill the process

Then delete the file
C:\WINDOWS\wupdt.exe

You have mediamotor/ popuppers

Kill the process [popuppers64]
Run Hijackthis with all windows closed and choose scan only and select those entries and choose fix.
Locate and delete
C:\WINDOWS\a64sddd.exe
Go to IE tools/ internet options/ security/ trusted zone/ sites and make sure those sites are gone.


You have adware delfin
http://securityresponse.symantec.com/avcenter/venc/data/adware.delfin.html
O4 - HKLM\..\Run: [motoin] C:\WINDOWS\mm15201518.Stub.exe
Kill process, run hijackthis and fix entry , delete file.


O4 - HKLM\..\Run: [ViewMgr] C:\Program Files\Viewpoint\Viewpoint Manager\ViewMgr.exe
Uninstall with add/ remove programs , and have hijackthis fix this. Delete the folder C:\Program Files\Viewpoint You do not want all the movies and songs you view/ listen to reported.

O16 - DPF: {FF65677A-8977-48CA-916A-DFF81B037DF3} (WMService Class) - http://download.overpro.com/WildApp.cab



Reboot, if you have not yet done so disable system restore and reboot again.
Run hijackthis and post a new log.
