I.I.Dangerous Viruses

If you are reading this thread then you must be a member or guest on Greyhat-Security,that means you like downloading stuff,off the web. But you never know if the stuff you download are clean and have no viruses. But then one day,you download something and you reboot and then ,what do you know? Some files are created by themselves,some files can't be accessed. What to do? Go to Google and download an Anti-Virus,here are some links:
AVG-

Code:

http://free.grisoft.com/

Avast-

Code:

www.avast.com/eng/download-avast-home.htm

Kaspersky-

Code:

www.kaspersky.com/downloads

NOD32-

Code:

www.eset.com/download/

When you download,install,update and run a full scan. Your windows is now cleaned from viruses. To make sure,scan again.

Then download Spyware Doctor here:

Code:

Download,Install,Update and run a full scan. Your windows is now cleaned from Spywares.

Then download a malware remover:

Code:

YOUR WINDOWS IS NOW CLEAN.

Now when you finish the above,use Disk Cleanup to delete anything unwanted. And then run Disk Defragmenter. Your windows is now back to normal.


I.II.Blue Screen
Blue screen a.k.a Blue screen of death is an error that windows xp has. It is mostly there when you have a system error.And that blue screens saves the day. It helps you prevent any damage to your computer by shutting it down. How to recover from Blue screens:
Get your windows xp installation cd Stash it inside your CD-Rom and restart computer. And boot from the cd. When a blue window i think will come up click R Type in Quote:
CHKDSK /R

and enter. When the repair process is done type in Quote:
BOOTCFG

.
When that is finished restart and keep your finger on F8. When a black windows comes up with option select Quote:
Last Known Good Configuration

Your windows is now recovered.

I.III.Error messages
Some error messages show at startup and some when starting an application. I will talk about both. For the error messages at startup is probably a missing DLL,I will talk about that later. And sometimes it a unknown message sent to a window component like autoexec.bat or command.com(this also will be discussed in the Missing DLL part) For starting an application sometimes it's the setup file,maybe a file wasn't completely installed use Reinstall in the Add/Remove Programs,but some programs don't have Reinstall so just Uninstall and install again,if the problem persists then it is the download link. Try downloading from another source.
Like if you are going to download for example LimeWire.Don't download from http:

Code:

//www.download.com

but from

Code:

http://www.limewire.com

.
Always better to download from original site.

I.IV.Missing Dlls
When something bad happened a DLL is corrupted. Dll's are mostly in System32. So find your corrupted DLL(To find the corrupted DLL take a look at the startup erro,you should see the dll name there. When you find your DLL go to :

Code:

http://www.dll-files.com/

And search for it. When you find it download and replace it with the old DLL.

Then download registry booster 2 here:

Code:

http://www.liutilities.com/products/registrybooster/

And run a full scan. That should clear things out. Then go to RUN and type drwatson.exe, drwtsn32.exe or dwwin.exe depends on your windows version. And follow this Wiki:

Quote:
The information obtained and logged by Dr. Watson is the information needed by technical support personnel to diagnose a program error for a computer running Windows. A text file (Drwtsn32.log) is created whenever an error is detected, and can be delivered to support personnel by the method they prefer. A crash dump file can also be created, which is a binary file that a programmer can load into a debugger. Dr. Watson can be made to generate more exacting information for debugging purposes if the appropriate symbol files are installed and the symbol search path (environment variable) is set. When a program error occurs in Windows, the system searches for a program error handler. A program error handler deals with errors as they arise during the running of a program. If the system does not find a program error handler, the system verifies that the program is not currently being debugged and considers the error to be unhandled. The system then processes unhandled errors by looking in the registry for a program error debugger for which Dr. Watson is the default. A third-party debugger can also be used in place of Dr. Watson. The Watcom C compiler includes a similar crash-analysis tool named "Dr. Watcom"


I.V.Minor Viruses
When you have small,spammy,annoying viruses a system restore might be your best bet.

I.V1.Very Dangerous Viruses.
Very dangerous viruses cannot be cleaned with a Anti-Virus,but only with a format. Here I will teach you how to format:
First make a backup and stack all your needed files inside.
Then stash your Windows Xp installation cd inside the CD-Rom.
Restart and boot from CD.
A blue window will appear and look down you will see different
options.Don't click any,be patient and you will see that the cd is
running some files you will see name(like sound device...)When that is
done you will see options,Click enter.
A new window will appear.You can see all your drives/partition.Choose
your system drive , or the drive that you want to format and click
"D"(sometimes you only have C:/ and no D:/ so the step before is not
needed).New window,press L.
You are back to the previous screens,but instead of C:/ \ D:\ you have
sizes ( e.g 1515MB ),highlight the size and click C.New window,click
enter.
Previous Window.You will have something that looks like this : “C: Partition1..."Highlight and press enter.
New window choose NTFS(this is just my recommendation),there will be a 4 options i think, quick and full i don't know,but don't choose quick choose the other one and click enter. That will format. Than there is the configuring it's up to you. When you finish configuring install the windows drivers and that's it a new windows.

II.Preventing
So you just been saved from the viruses and now you don't want to make the same mistakes again? Here is how.
Always use the internet using a proxy , it will be almost impossible to connect to you. Then change IPs every now and then.
Tick your firewall on. And every 2 weeks update your windows. Always use an Anti-Virus. Check your download links. Always use fake Email-Address , and Fake Name. Disable telnet/NetBIOS. Never download hacking tools that you think might be viruses. Prevent yourself from making batches and saving them as something.bat( because if they are destructive you don't know when it will
automatically launch. DO NOT USE P2P for softwares,maybe for music. If a friend tells you I created a similar website to Myspace/Gmail/Hotmail.. Don't accept it's probably phishing. Make sure that you never log on MSN at your friends house as it might be keylogged.
