No, You misunderstood my question. I know what is R0 to R3. My question is why my scan result has no R1, R2 & R3 but the log starts from O1 onwards. A normal scan will consist log that starts from R1 or R0 onwards but mine is that R0 to R3 is missing from the log.

Hope your understand my question.

Please advice and thanks in advance.

R0,R1,R2,R3 Sections

This section covers the Internet Explorer Start Page, Home Page, and Url Search Hooks.

R0 is for Internet Explorers starting page and search assistant.

R1 is for Internet Explorers Search functions and other characteristics.

R2 is not used currently.

R3 is for a Url Search Hook. An Url Search Hook is used when you type an address in the location field of the browser, but do not include a protocol such as » or »ftp:// in the address. When you enter such an address, the browser will attempt to figure out the correct protocol on its own, and if it fails to do so, will use the UrlSearchHook listed in the R3 section to try to find the location you entered.

Some Registry Keys: HKLM\Software\Microsoft\Internet Explorer\Main,Start Page
HKCU\Software\Microsoft\Internet Explorer\Main: Start Page
HKLM\Software\Microsoft\Internet Explorer\Main: Default_Page_URL
HKCU\Software\Microsoft\Internet Explorer\Main: Default_Page_URL
HKLM\Software\Microsoft\Internet Explorer\Main: Search Page
HKCU\Software\Microsoft\Internet Explorer\Main: Search Page
HKCU\Software\Microsoft\Internet Explorer\SearchURL: (Default)
HKCU\Software\Microsoft\Internet Explorer\Main: Window Title
HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings: ProxyOverride
HKCU\Software\Microsoft\Internet Connection Wizard: ShellNext
HKCU\Software\Microsoft\Internet Explorer\Main: Search Bar
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\URLSearchHooks
HKLM\Software\Microsoft\Internet Explorer\Search,CustomizeSearch =
HKCU\Software\Microsoft\Internet Explorer\Search,CustomizeSearch
HKLM\Software\Microsoft\Internet Explorer\Search,SearchAssistant

Example Listing R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start Page = »www.google.com/

A common question is what does it mean when the word Obfuscated is next to one of these entries. When something is obfuscated that means that it is being made difficult to perceive or understand. In Spyware terms that means the Spyware or Hijacker is hiding an entry it made by converting the values into some other form that it understands easily, but humans would have trouble recognizing, such as adding entries into the registry in Hexadecimal. This is just another method of hiding its presence and making it difficult to be removed.

If you do not recognize the web site that either R0 and R1 are pointing to, and you want to change it, then you can have HijackThis safely fix these, as they will not be detrimental to your Internet Explorer install. If you would like to see what sites they are, you can go to the site, and if it's a lot of popups and links, you can almost always delete it. It is important to note that if an RO/R1 points to a file, and you fix the entry with HijackThis, Hijackthis will not delete that particular file and you will have to do it manually.

There are certain R3 entries that end with a underscore ( _ ) . An example of what one would look like is:

R3 - URLSearchHook: (no name) - {CFBFAE00-17A6-11D0-99CB-00C04FD64497}_ - (no file)

Notice the CLSID, the numbers between the { }, have a _ at the end of it and they may sometimes difficult to remove with HijackThis. To fix this you will need to delete the particular registry entry manually by going to the following key:

HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\URLSearchHooks

Then delete the CLSID entry under it that you would like to remove. Please leave the CLSID , CFBFAE00-17A6-11D0-99CB-00C04FD64497, as it is the valid default one.

Unless you recognize the software being used as the UrlSearchHook, you should generally Google it and after doing some research, allow HijackThis to fix it
