These are the tools used in removing virus manually:
- Process Explorer
The Process Explorer display consists of two sub-windows. The top window always shows a list of the currently active processes, including the names of their owning accounts, whereas the information displayed in the bottom window depends on the mode that Process Explorer is in: if it is in handle mode you'll see the handles that the process selected in the top window has opened; if Process Explorer is in DLL mode you'll see the DLLs and memory-mapped files that the process has loaded. Process Explorer also has a powerful search capability that will quickly show you which processes have particular handles opened or DLLs loaded.
- a-squared HiJackFree
a-squared HiJackFree is a detailed system analysis tool which helps advanced users to detect and remove all types of HiJackers, Spyware, Adware, Trojans and Worms.
- Trend Micro HijackThis
HijackThis lists the contents of key areas of the Registry and hard drive--areas that are used by both legitimate programmers and hijackers. The program is continually updated to detect and remove new hijacks. It does not target specific programs and URLs, only the methods used by hijackers to force you onto their sites.
It is used to delete any file including access-denied files.
- Security Task Manager
Security Task Manager shows comprehensible information about programs and processes running on the computer. For each Windows process, it improves on Windows Task Manager, providing unique security risk rating, comments from our experts and user community, free online scan with all known Antivirus engines, full directory path and file name, process description, CPU usage graph, embedded hidden functions and process type.
