Search Engine Redirect Problem

I got a seach engine redirect problem. Yahoo!/Google/Bing on Safari/IE, search result links randomly get redirected to various ad search engines or pages.

I've tried everything including HijackThis, and the problem persists.

From what I've been reading on similar forums, I think I need to try ComboFix.

Can someone help me?

We don't handle malware cases in here. I suggest that you read this & post another thread here. You are advised not to do anything with HJThis other than the scan unless one of our experts instruct you to. Currently none of the malware experts are online but they should be tonight. The general rule of thumb is 24 hours.

I'll move over to the other forum.

Thanks.
