Well this is my first time in the forums So hello to everybody.

Now onto my problem:

My Homepage is set to about:Blank( a search for... site) and everytime i change it back to may normal homepage it changes back to that about:Blank.

Ran ad-aware, spy-bot, AVG not seems capable of fixing it. This problem appeared right after my AVG detected a backdoor.agent.BA.

Here's my hijackthislog

Try the same fix again, then Download CWShredder from here & run it. Select the fix button & it will get rid of everything related to CoolWebSearch that is stored in it's database. Close ALL windows, including IE, before running CWShredder. Reboot.

To help prevent this from happening again, install the patches for the vulnerabilities that this hijacker exploits by going here for your critical updates.

Then disable system restore & re-enable it following the instruction here.

Note that all previous restore points will be lost.

Reboot after doing this & post another log please.

Ok here's the log
