Re: virus infecting microsoft programs
Its the W32/Rungbu-A virus, it infects Microsoft Word DOC files by
copying itself to the same filename but with an .SCR extension,
appending the DOC file to the SCR copy, and then hiding the original
The W32/Rungbu-A then sets the computer not to show
hidden files (in order to hide the DOC file), to give SCR files a Word
icon (so the SCR file looks like a Word file), and to hide file
extensions (so the SCR file just displays the filename, not the SCR
extension). When the SCR file is run, the Word document is displayed as
To recover your .DOC files just follow these steps:
You have to delete all files detected as W32/Rungbu-A.
Set the following registry entries in order to show extensions and hidden files:
You must change the attributes of the original .DOC files to stop them being hidden.
My answer to your second question, is in November of 2007 the .SCR file extension started to be used to transmit
a Trojan. As a script or a screen saver this file can execute other
files which carry the Trojan. The SCR file may be embedded within a ZIP
file which could also contain a file with a double extension. Many Windows screen savers come with a .SCR extension by default.
Usually these will be found in the Windows main directory. Use caution
if you receive a screen saver file via E-mail. These files can contain
executable code and can be worms or viruses. Note: This file type can
become infected and should be carefully scanned if someone sends you a
file with this extension.

Removing viruses, though technical, is yet a very simple process if all the required steps are properly followed.
The basic steps are:
Buy or download a reliable antivirus software
Install the antivirus software
Update antivirus software with the latest virus definitions
Perform a complete system scan
Install an Antivirus Program in the System
What is Antivirus program? An antivirus is a program that searches for, identifies and removes potential viruses existing in the computer system. Antivirus software: Some of the most commonly and reliable antivirus programs available in the market are -
Symantec Norton antivirus
The antivirus software should be updated regularly to retain its effectiveness.
Before installing the antivirus, close all open applications and
terminate any suspicious processes using Task Manager. Sometimes, you
may need to boot into safe mode or safe mode with command prompt to
delete suspicious programs and references to them in the Windows
Registry (run regedit from the command prompt to open the registry
editor). Search engines are
excellent tools to find out whether a certain process is harmful or not.
You can also get steps on how to remove a specific virus manually.
Removing the virus beforehand might be necessary, as some viruses
will not allow an antivirus to operate. However, if you are not
successful, you may still continue with the installation.
Scan the System to Identify and Locate the Virus
Usually, the antivirus will run automatically when the system reboots
after the installation. Therefore, it might identify the virus
automatically. Moreover, you may want to run a quick system scan to
locate the virus.
Troubleshooting the Virus Infected Areas
After the antivirus identifies the infected areas, the next step is to rectify those areas. Methods of Eliminating Viruses
Generally, the antivirus adopts one of two methods to eliminate the virus:
Removing the virus - When the
virus can be easily identified and can be removed without affecting
other files, then the antivirus removes it from the host place.
Quarantine - his is done when
the virus cannot be easily identified removed from the file and the
removal of virus means the removal of the complete file. In this method,
although the virus is not eliminated, it is rendered inactive by moving
the file into "quarantine" and renaming it.
Perform a Full System Scan
Even after the virus is removed from the system, the next step is to
scan the whole system to ensure that no infected files remain.
There are 2 solutions to this problem.
1. Formatting of your laptop. as a result of formatting your laptop, you may loose valuable informations as well as programs.
2. Downloading a Norton 360 antivirus program into your laptop. after download, you can scan and fix viruses. this will work perfectly well.
If your computer doesnt allows you to perform a download, simply download from another computer into an external device such as a USB device and transfer the Norton 360 setup flies to your laptop and run it. after installation process, scan for viruses and fix.
I hope this helps.
It might be really what it says, but chances are you have accidentally
started a "fake virus scam" malware, that acts a bit like a virus, but
with an added function of luring you into paying for some miraculous
anti-virus, that will cure your computer of the multiple "infections" it
has allegedly "discovered". Whether or not it is a real infection, the best idea is to prepare on a clean computer (at a friend for example) a startup antivirus CD,
from which you could boot your computer and run an antivirus program.
You should have an antivirus program always running on your computer. If you have one it should be able to get rid of the virus. If you don't have one or you have one but it can't get rid of the virus, try AVAST. It is free at http://www.avast.com. Once you install avast, it will want to run a sweep before your computer restarts. That is the best way to get rid of a virus, before the virus is activated.
XP Antivirus 2008 is one of the latest counterfeit antispyware that devastates the wolrd wide web. XP Antivirus 2008 usually come up after you installed a video codec that come with Trojan, malware and virus.

This is one of the warnings from the net about this program.
a system restore with disks or a full reinstall may be in your future.... reboot and tap f8 and then boot to safe mode.... does that work ?
Format your disk and Reinstall operating system or find out which all are the infected registry and remove the virus registry contents manually.
or delete (hidden file) autorun.inf from all drives if it exists.
