"ssearch.biz" is a nasty one so I will leave it for one of the experts to help you. You will probably need more tools than what you listed. I'm also not familiar with "Doctor Spyware". There is a program that is called "Spyware Doctor", which is not condemned but is also not condoned. Also, what do you mean by "and the likes"? There are a lot of ripoffs out there so please be specific also what you are using. The others that you listed are good although there are a couple more I would add if you don't already have them.I'm just prepping you for one of the experts because they will probably ask you the same questions.
I have a problem with Trojan detected by McAfee as StartPage-EH. The antivirus says that the file being infected is BEHKNQTW.DLL (located in directory windows\system). However, the antivirus cannot clean it nor can it delete the infected file.
I then tried deleting it manually (by using both windows explorer and DOS command line but not succeeded that's to say the BEHKNQTW.DLL cannot still be deleted. Is that file required by the windows, I mean what file is it?
The symptoms I undergo is when I opened the IE Browser to a certain address, say www.yahoo.com. It redirects me to page http://ssearch.biz displaying look like Search Engine but Nothing can do with it.
I use Win98SE with IE v6, many removal tools I have been trying i.e. SpybotS&D, CWShredder, Doctor Spyware,Spyware Guard, and the likes. I also tried resetting Web Setting to its default
But the Trojan is still there. It comes back again.
Your help to get rid of this annoying thing will greatly be appreciated.
