How to Remove Happy99.exe (ska)

6/22/2009 09:32:00 AM Posted In Edit This 0 Comments »

These are the steps you can follow to remove Happy99.exe

Steps marked optional are not absolutely necessary and are completely safe to skip. If you’re not comfortable with DOS, get someone knowledgeable to help you with this. I cannot make guarantees of perfect safety since its a manual removal, Perform these at your own risk. If you have Windows NT, you don’t have to follow the removal steps.

1. Click Start, then Shut Down, then “Restart Computer in MS-DOS mode”, then click Yes. It’s important to exit Windows in order to be able to replace the file WSOCK32.DLL which Windows normally has in use.

2.At the DOS prompt type this exactly and press enter at the end of each line:

CD \WINDOWS\SYSTEM

3. Delete SKA.EXE and SKA.DLL by typing

DEL SKA.EXE
DEL SKA.DLL

If you get “File not found” you’re either not infected or in the wrong directory. Make sure you’re in your Windows System directory; check to see if you followed step 2 exactly.

4.Copy WSOCK32.SKA to WSOCK32.DLL by typing

ATTRIB -R WSOCK32.DLL
COPY WSOCK32.SKA WSOCK32.DLL

Answer “Yes” if it asks if you want to overwrite WSOCK32.DLL.

WSOCK32.SKA is a backup of the original WSOCK32.DLL. You are replacing the modified DLL with the original. If you get a “Sharing violation” make sure you followed step 1.

5.Optional Delete WSOCK32.SKA by typing

DEL WSOCK32.SKA

You can leave WSOCK32.SKA on your system. It is a copy of your original WSOCK32.DLL Do not delete WSOCK32.SKA if you are unable to replace WSOCK32.DLL with WSOCK32.SKA.

6.Return to Windows by typing

EXIT

7.Optional Delete Windows Registry Key.
Click Start, then Run, then type regedit in the text box, then click OK. Click HKEY_LOCAL_MACHINE, then Software, then Microsoft, then Windows, then CurrentVersion. Under RunOnce check for SKA.EXE and select it if it is there. Press delete and then click Yes. Close Regedit. Don’t change anything else without making a backup of the registry first. If you don’t find SKA.EXE in the registry, it doesn’t mean you’re not infected. SKA.EXE is only added to the registry if HAPPY99.EXE is unable to modify WSOCK32.DLL when you run it. Also, you’ll only find it in the registry if you haven’t rebooted since you ran HAPPY99.EXE.

8.Optional Choose Start, Programs, Accessories, Notepad, choose File, then Open then type C:\WINDOWS\SYSTEM\LISTE.SKA in the File Name box. Warn the people on the list, then delete LISTE.SKA. Make it clear to the people you warn that they won’t be infected unless they ran happy99.exe, to avoid alarming them unnecessarily. If you haven’t sent out any infected e-mails, there won’t be a LISTE.SKA.

9. Optional Delete the HAPPY99.EXE file. The location of HAPPY99.EXE will vary depending on where you saved it. You can delete it simply by dragging it to the Recycle Bin from within Windows or whatever method you prefer. You may still have some messages with HAPPY99.EXE attached in your mailbox. These cannot do anything unless you run them. You can delete them if you want to or just ignore them. 10.Optional If you aren’t sure whether WSOCK32.DLL is infected, choose Start, then Find, then “Files or Folders”. Then type WSOCK32.DLL in the “Named” box. In the “Look in” box choose drive C: or whatever drive you have Windows on. In the “Containing Text” box type “ska.dll” without the quotes. Then click “Find Now”. If you don’t find any files, that means that wsock32.dll isn’t the modified version. If you don’t have the modified WSOCK32.DLL, the virus has no way to attach to e-mails, even if you have SKA.EXE, SKA.DLL, and WSOCK32.SKA in the Windows System folder. If you have SKA.EXE in the RunOnce registry section, and you haven’t deleted SKA.EXE, then the virus will try to modify WSOCK32.DLL the next time you restart the computer.

How to remove SCVHOST.exe (W32/YahLover.Worm.gen or Win32/Autorun.R.worm)

6/22/2009 08:53:00 AM Posted In Edit This 0 Comments »

This virus/worm installs itself in autorun.inf and once double click it will spread itself unto your system. Furthermore, it copies itself through all the shared folders on your computers throughout the network and installs itself in the registry entries remotely.

Here are indication that your computer is infected with this virus.

  • This virus/worm blocks the task manager
The worm changes the registry to prevent running task manager and editing registry for harder detection.
  • It automatically restarts the computer when you try to go to the command prompt.
  • It duplicates itself to different locations of the shared folders. The duplicated virus/worm uses a FOLDER icon with an .exe file extension. WARNING! DO NOT double click these folders.
  • It autostart via registry keys Windows->Run and add itself to WinNT->WinLogon->Explorer.exe

How to remove the virus

You can use NOD32 or any strong antovirus programs to remove this virus but if you don’t have a anti-virus or your antivirus can’t remove this virus try following the steps below to remove it manually.

  • Boot your system in Safe Mode Command Prompt Only
  • After you log-in the command prompt will be opened (LOG-IN AS ADMINISTRATOR).
  • Type CD C:\WINDOWS\SYSTEM32 (I assume that your Windows System files are located at Drive C)
  • Type DIR /ah, this will display all hidden files on this directory folder. You will see the following files which is used by the virus to spread itself: AUTORUN.INI, BLASTCLNNN.EXE, and SCVHOST.EXE
  • Type ATTRIB -H -R -S SCVHOST.EXE
  • Type ATTRIB -H -R -S BLASTCLNNN.EXE
  • Type ATTRIB -H -R -S AUTORUN.INI
  • Type DEL SCVHOST.EXE
  • Type DEL BLASTCLNNNN.EXE
  • Type DEL AUTORUN.INI
  • Type CD\
  • Type ATTRIB -H -R -S AUTORUN.INF
  • Type DEL AUTORUN.INF

After following the steps on removing the virus/worm files, the virus should now be removed from the registry of your system.

  • At the command prompt type REGEDIT and press ENTER key. This will run the Registry Editor
  • From the registry, look for the keys: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run, you will see an entry Yahoo! Messengger (it’s spelled like this) with a value c:\windows\system32\scvhost.exe, Delete this entry.
  • Look again for the key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon, there’s an entry named: SHELL, it has a value = Explorer.exe SCVHOST.EXE , DON’T delete this entry!!! Just edit this entry and REMOVE the SCVHOST.EXE so that Explorer.exe will be the only value that remains from this registry entry.

After carefully following all the steps restart your computer on normal mode and the virus should now be gone.

A computer can be restart because automatically downloaded an update package needs install its updates and work out this by itself restarting the computer. Probably these could be malicious programs.

  • Overheating:
Overheating of the parts also cause for this kind of matter. In fact the proper response of a computer to overheating is the power off. Nothing is gained by restarting. However overheating could cause the BIOS or power supply to malfunction causing it to restart.

You can improve the airflow through the machine or invest in a water-cooling system. These are favored by gamers, who put a lot of stress on machines heating them up.

  • Microsoft Auto Update:
Microsoft Auto Update can force a reboot to the after countdown (Many pc's are set to do this at 3am by default) if the update requires a dll reload/change.

  • Remotely Shutdown:
Also someone can use shutdown -i which is a command to remotely shutdown a computer all they would need is an IP address (Internet protocol Address).

A measure of the width of a range of frequencies, measured in hertz

  • Spectral line bandwidth:
The width of an atomic or molecular spectral line, measured in hertz

Bandwidth can also refer to some other specific areas too:

Dynamic IP Address vs Static IP Address

6/22/2009 06:03:00 AM Posted In Edit This 0 Comments »
Computers use IP addresses to locate and talk to each other on the Internet. It is the unique identifier of a computer on the net.

A dynamic IP is an address that is assigned your computer temporarily by ISP when you connect to the internet

For the duration of you connected it will remain the same IP address but when you disconnect and reconnect you will probably be given a new (different) IP address. The IP address you had before will be given to someone else.

A static IP address is an IP address that is assigned to you computer by an Internet service provider (ISP) to be its permanent address on the Internet. Every time you’re connected the same IP address will be assigned.

If you need to make your dynamic IP address into static IP probably you have to contact your ISP (Internet service provider) and ask them for assign you a static IP. So you can have an IP address permanently assigned to you which you can use every time you are connected.

Making your IP address static cannot done yourself because an IP address needs to be globally unique, you can't just pick one for yourself as you desire. It needs to be assigned to you by your ISP.

  • Advantages of having Dynamic IP:
1. If you have a hole in your firewall and a dynamic IP, then every time you disconnect and reconnect any hacker who found you by your IP address on the first visit, will much more difficult to find you again because your address will be different.

2. Fixing IP bans from Forums, chartrooms and etc.

3. Override Time limitations which are depend on the IP address (I.e. Rapidshare).

  • Advantages of having Static IP:
The only reason I know why you would need a static IP is if you want other users to be able to connect to your computer through internet. (I.e: Web server)
