Have a Malware problem-Hijack this won't launch

Hello Malwareremoval.com. My name is Mike B and I was here once before. First I will say that I have put Hijack this onto this computer as instructed. However it will not launch when double clicked on. I've removed it and tried it several times and it will not launch. Part of my computer's new problem? Not sure. Anyway around this?
I first recognized this problem early this morning-July 6,2009. Whenever I do a search on Yahoo,Google,etc... the search engine
completes the search. However when I click on any of the results I am not directed to the website searched for. I am always directed elsewhere. Here is a example. I searched for Lance Armstrong,I click on the result -lancearmstrong.com-and I click on it and I'm directed here:http://www.toseeka.com/search.php?q=Lance+Armstrong. Any help is appreciated. Thanks Mike B

We understand that you are having difficulty running HijackThis. However, in order for us to help you it is necessary that you provide us with a HijackThis log, and it is possible you may be able to trick the malware into letting you do this. First, download HijackThis to a clean computer, then rename it from HijackThis.exe to any other name you want, using an .exe extension, for example... YourLastName.exe. Once you have done that, burn it to a CD (preferable to using a flash drive that may easily become infected) then transfer the renamed file to the infected computer and run a scan, then start a new topic and include your HijackThis log.

Please follow the guideline at the link below to start a new topic and post your HijackThis log. If you are unable to create and post a HijackThis log, then your only option may be to reformat your computer and reinstall the operating system.

This topic is now closed. Please start a new topic by following the HijackThis Guideline posted here, just be certain to rename HijackThis: >Guideline for posting your HijackThis log<
