About three weeks ago, I got some troubles with my laptop. This was after I plugged a USB 
FlashDisc into it. I clicked a random file in the USB Disc, stupid me, I didn't scan it before. As a result, there were 2 kinds of virus infected my laptop, the first one should still be considered as worm I guess. But the second one was a real threat to my laptop. It was SALITY !!!!

Indeed, this was also caused by my stupidity for neglecting the importance of AntiVirus. Hence, to avoid the same thing happens to you, guys, I suggest to use these AntiViruses :
Moreover, for you who often connect your PC or laptop to the internet. Those AntiViruses will be your PC/laptop's protectors from viruses' threat.
You might think that I'm just promoting others' products. Well yeah, I was also a person who was not really care about AntiViruses. But SALITY changed my mind afterwards.
Just to share you my experience, I worked hard to get rid of SALITY for the virus was really annoying me. With an assistance from a colleague, UCILELEK, I and him had to stay awake for the whole night, just to kill it
TEMPORARILY, as I thought it was solved but unfortunately appeared again and spread a massive threat just the day after. Damn !!! SALITY even ruined most of my Program masters and saved games. What a threat, ha?? Anyway, to answer my curiosity about SALITY, I managed to get more info about it. Here is what I found, just if you, guys, want to know more about it.
Continuing my previous post on SALITY VIRUS, here I would like to share some other facts about it which i just found.

===========================================================================
In addtion, sality W32 is an appending file infector virus that uses an entry point obscuring technique to hide its presence on the system. What's sophisticated is that Sality has the ability to download and install additional malware on the system. Moreover, can also terminate the running AntiVirus program.
When Sality has infected your computer or laptop, [System]\drivers\[random].sys is dropped into the system and will be detected as Virus.Win32.Sality.ab.
Soon it will copy itself to removable drives and shared folders as one of the following :
• [randomname].exe• [randomname].pif
• [randomname].cmdt
After that Autorun.inf will be formed so that he malware will be executed when it is connected to a computer.
It also modifies %windir%\SYSTEM.INI by adding the following section :
• [MCIDRV_VER]DEVICE=[random alphanumeric string]
Once on the system, the virus searches the hard disk (starting with C:\) and infects any files with the following extensions:
• .exe• .scr
It also infects files with .EXE extensions that are referenced as data in the following registry keys:
• [HKCU\Software\Microsoft\Windows\CurrentVersion\run]
• [HLKM\Software\Microsoft\Windows\CurrentVersion\run]
The virus appends itself by creating a new 73728 bytes sized section named "[random characters]data". The section contains Sality.AA's obfuscated code.
When run, Sality.AA creates a mutex to ensure only one instance is running. It then modifies a large range of registry entries. The virus attempts to disable processes and services containing strings related to major antivirus software.
The malware connects to the following website to verify an Internet connection
• http://www.microsoft.com
The malware may connect to the following sites to download and execute additional malware :
• http://kukutrustnet777.info/[...].gif
• http://kukutrustnet888.info/[...].gif
• http://kukutrustnet987.info/[...].gif
• http://www.musikrajt.sk/[...].gif
• http://macedonia.my1.ru/[...].gif
• http://jrsx.jre.net.cn/[...].gif
• http://www.musikrajt.wz.cz/[...].gif
• http://www.solidarnosc.org.pl/lublin/[...].gif
• http://gotcha.goldeye.info/[...].gif
Downloaded files are encrypted. They are unencrypted by the malware to the %temp% folder and executed.
The following URLs may possibly be used to get further instructions:

*** PS: I had to re-install my OS for SALITY had too much ruined my systems and programs
