I would recommend using any available linux live CD (could be some cover disk from magazine related to nix) and USB media to save your work files. Then using restore CD for notebook to get it back to work. That's in general. Otherwise one needs more information on what's working, OS type and such.

Virus alert


Glad to HELP YOU!

Well, it depends on what kind of AntiVirus software you do have installed on your machine.
Some like Kaspersky or BitDefender are tagging many files as being "viruses" EVEN they are not harmfully!
Just go in the VAULT of your AntiVirus software and see the file; if it souns "familiar" (like a driver or an executable file) and you trust it just choose IGNORE and you will "bypass" the "virus alert".
But if looks "odd" and "unfamiliar" just run a SYSTEM CHECK with your AntiVirus. You will never know.
Always remember where you have been taking your files from! If are UNTRUSTED web sites it's a rule of thumb to scan such files!

GOOD LUCK!

How to Reduce Spreading of Virus on the Hard Drive


<b><u>An insight in VIRUS INFECTION and VIRUS SPREADING</u></b><br /> <br /> In today's computing spreading of virus is fast and very common.<br /> Even with an up to dated antivirus software the spreading of the virus infection is fast.<br /> This is because, we are not aware of how the virus spreads in our system.<br /> Once we know how the virus infects and spreads in our system then we will definitely reduce the risk, time and money spent.<br /> <br /> <b><u>Here is a short insight about viruses:</u></b><br /> <br /> 1) Virus is a small program code enabling it to to mingle or merge with other program codes.<br /> <br /> 2) The Virus Program Code is written such that it deletes data, corrupts data, steals data send it to the maker of the code, etc.<br /> <br /> 3) The virus cannot run on its own. It has to be executed just like other exe program files. That is why the autorun.inf file is required.<br /> <br /> <b><u>Now for an insight how we get infected:</u></b><br /> <br /> 1) Thorugh the internet: Usually when we browse any web site files are downloaded from the web server to our temporary internet folder(in windows) Then our Browser software reads the files and executes them in the browser window for us to view the web site.( If you are a website Designer you would understand this for others get an insight how internet browsers work), So when we are in the internet Virus files attach themself to the downloading files and enter our system in the temporary folder, From here they are executed by our browser software or when any program accesses the temporary folder.<br /> <br /> 2) Another one is we download a lot of data from the internet, we should be careful on what we are downloading because if the data downloaded is infected with virus then we are downloading the virus to our system along with the data, Don't download the data unless you are sure you could trust the maker of the data, program,etc.<br /> <br /> 3) From other medias like Flash Drive, CD's, DVD,s,etc.:<br /> We copy a lot of data to our computer from our friends and relatives, so if the data is already infected with virus we copy the virus to our system also, when we run os use the data the virus is executed along with it.<br /> <br /> <b><u>Now for an insight how Virus Spreads:</u></b><br /> <b></b> <br /> Just like any other program code the virus code has to be executed.<br /> That is why the virus merges with other exe's which are executable and not with the data file.<br /> <br /> For eg: a file with .avi, .dat, .3gp, etc. all these files are data files they dont execute, but they are used by exe files like wmplayer.exe, winamp.exe, vlplayer.exe, etc. The .avi .dat .3gp files are data files, the wmplayer.exe, winamp.exe vlplayer.exe are program files. Thus mostly exe program file get infected with virus.<br /> <br /> Usually when our system gets infected and any antivirus program cleans our system you can notice that the windows media player or winamp player or vlc media player does'nt work because it is removed or deleted by the antivirus for virus infection but the songs or video you saved is unharmed in the harddisk.<br /> <br /> That is why the virus code hangs or merges or infects mostly exe program files, So that it is executed along with the program file.<br /> <br /> So when you run an infected windows media player to play a song the virus code is also run along with the windows media player. Thus the virus is run again and again.<br /> <br /> There are hundreds of program files in the os for doing various tasks.<br /> we are going to look into just one program which the virus uses to spread itself in our system.<br /> <br /> The Program is non other than explorer.exe in windows. This program is needed to view or browse the data files stored in the hard disk.<br /> When we double click the My Computer Icon on the desktop the explorer.exe is executed which show you a window on your screen with the hard disk drives and cd dvd drives in the windows Now you can imagine how frequently you use the explorer.exe. You use it to view any data on the computer, even our desktop uses explorer.exe. This program is executed right when windows logs us on.<br /> <br /> When this program file is infected, it keeps on executing the virus each time we use the program. by this method the virus spreads fast to every parts of the hard disk.<br /> <br /> Likely there is a method to avoid executing the virus along with the explorer.exe each time we use it.<br /> <br /> When we double click any icon or object on our windows screen we execute the default command in the right click menu. Usually it is the Run Command. for eg: when you double click word the word.exe runs, similarly when we double click the my computer icon the default right menu option is <b>Open</b> which run the explorer.exe program.<br /> <br /> Instead of using this method to view files and data in our system we could use an alternate method which is using the explorer menu option when we right click my computer or right click the windows start button or in fact the explorer option is there whenever you right click any object on the screen.<br /> <br /> By using this explorer option in the right click you get a window with two panes one to the left and one to the right. In the left pane you have the directory structure showing all the directories and folders in our hard disk and in the right pane the content of the directory or folder selected in the left pane.<br /> <br /> Thus in this process we dont execute any code or program command when viewing the data in our hard disk. because we do not execute the explorer.exe more than once.<br /> <br /> So, Imagine how we reduce the spreading of virus by using this method.<br /> <br /> Say you have a file saved in your hard disk in this location<br /> <br /> <b>C:\data\monday\20-11-2010\office\media\todaysjob.doc</b><br /> <br /> If you want to open the file with word we will double click my computer, then double click C Drive, then Double Click data folder,then double click monday folder, then double click 20-11-2010 folder, then double click till you come to the media folder then you double click the todaysjob.doc which will execute the word.exe program which reads the data in the todaysjob.doc file and displays the content as required. In this process see how many time you will execute the virus, You will run the virus Seven Times.<br /> <br /> In our Alternate method You will run the Explorer.exe only once, Then on you just navigate to the media folder then double click the todaysjob.doc file in the right panel. So you execute the virus only once. <br /> <br /> Hence you reduce the spreading of VIRUS to a great extend.<br /> <br /> Good Luck, If there are any mistake please bare with me, I am not a good writer. If you have any Question Keep Me Posted.

Trojan Horse Removal


A virus is program that has malicious content in it and replicates itself and a Trojan horse is program that will only work if the user executes it. Sometimes, a Trojan horse covers itself as a fake folder while in fact, it's an .exe file.
The good thing about Trojan horse is that it is not that hard to get rid of them. But the bad thing about Trojan horse is that it is a little bit difficult to find them.
Although, it does not corrupt files or delete data stored on your hard disk until you execute it. Once executed, it will allow the hackers to indentify your credit card number, social security number, bank account details or some other private information.
You can delete or remove the hidden Trojan horse with the help of antivirus software. Either, you can also try the manual process to delete it or you can follow these steps:
STEP 1 Open the System Information Utility (msinfo32.exe). You can find the System Information Utility by typing “msinfo32.exe” in ‘Run’. This program lists all the processes running on any Windows system, even those processes that are hidden from the task list. Now open your virus scanner and run the executable or .dll through it.
STEP 2 Open your antivirus software and run a virus scan. If you don't have a antivirus software installed, download AVG Anti-Virus Free Edition 7.5. And run a scan using it. After the scanning process is completed, delete the value that was detected from the registry (before doing this step, take a backup of the registry files):
A) Click ‘Start’ > ‘Run’.
B) Type "regedit".
C) Click "OK".
D) Go to the subkey:

HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRun
HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRunServices
HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRun
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServices

E) Now delete any value from the right pane that was detected during the scan process.
F) Exit the Registry Editor.

What is virus and their description


A computer virus is a computer program that infects files, make changes in OS , file system , & edits registry to spread itself for furthur infection. They do it by putting their own code into the exe file & executes as a normal program & creates problems like deleting/hiding data,download programs from particular websites automatically,denial of service,formatting disk & much more.
Commonly we use the term virus for all types of malware,spyware.
A true virus can only spread from one computer to another (in some form of executable code)when its host is taken to the target computer; for instance because auser sent it over a network or the Internet, or carried it on aremovable medium such as a floppy,cd & USB drives(most chances).
