Sality Virus

Sality Virus (Win32 Sality Virus)(W32.Sality.AO, W32.Sality.Z)

Sality Virus is presently giving a headache to cafe owners today. That is why i wanted to post this information about this type of
bothersome Virus. Sality is a family of file infecting viruses that spread by infecting exe and scr files. The virus also includes an autorun worm component that allows it to spread to any removable or discoverable drive. In addition, Sality includes a downloader trojan component that installs additional malware via the Web.

How would i know if i have this kind of Virus in my Computer or Computers?
As with many other malware, Sality disables antivirus software and prevents access to certain antivirus and security websites. Sality can also prevent booting into Safe Mode and may delete security-related files found on infected systems. To spread via the autorun component, Sality generally drops a .cmd, .pif, and .exe to the root of discoverable drives, along with an autorun.inf file which contains instructions to load the dropped file(s) when the drive is accessed. The Sality virus joins infected machines to its own P2P network. Updates to the malware are fed via decentralized lists of HTTP URLs.

 What to do? How to Remove Sality Virus?
Understanding its characteristics is one helpfull way to remove or prevent your computers from this type of computer headache. You may search the web too for more ways on how to remove Sality Virus from your Pc's.


 1. Scan the system with up-to-date antivirus software. If a file is found to be infected with Sality, allow the antivirus software to clean the file. If other malware is found, allow the antivirus to delete or take the action recommended by the scanner. (For assistance, see Clean, Quarantine, or Delete?). If the malware persists, use a bootable antivirus rescue CD to boot the system cleanly and scan the system again. To prevent re-infection via infected USB drives, disable autorun.



2. Download the latest Panda AV software and after downloading, remove any antivirus sofware installed in your  computer   then run the installation setup of Panda AV and connect it for the latest updates. Then run for a Full Scan.Note do not run any programs and applications while having the full scan.After finishing scan.
 Restart your computer and you are almost done. Your computer is now safe in W32.Sality virus!

3. Download and install Kasperzky or NOD32 and update into the latest virus definition. Run a Full Scan immediately. After scanning has completed, restart you PC and you are done. Your PC is safe now.

Factors to consider when choosing Laptop Coolers

Laptop cooler’s sole purpose is to do one thing and one thing only, to cool down your laptop so that it doesn’t overheat and break down. Laptop coolers were designed with the purpose of blowing cool air towards your laptop to reduce the heat emitted from the internal system.


5 Factor to consider when choosing Laptop Coolers

Price - Choosing the best laptop cooler is not based on its price, there are good laptop coolers that can perform well as expensive ones. Since most of them can function equally. So you should pick one that is affordable and yet possesses a heigh quality.

Durability - You should choose the laptop cooler which are durable if possible with  a design that wont easily clogged up and is easy to clean, in such way you can get the most value of your money. 

Quietness - a noisy laptop cooler fan can be irritating. It is better that you should try to test it out before you buy it.

Portability and Size - The best laptop cooler should be very light in weight and can be powered through a USB port for energy.
When ever you are going to buy a laptop cooler, choose the appropriate size.

Cooling Power and Design - Some laptop coolers have multiple fans that make it more powerful than one with just a single fan. The positioning of the fans are important as well. Is it directly positioned where your laptop gets hot? How well does it keep your laptop cool? Two other key factors to examine are angle of the laptop cooler and the material of its surface. Is the laptop cooler angled to allow air to pass between the laptop and the laptop cooler? Is the laptop cooler made of plastic, metal or aluminum? This can greatly affect the cooling power of the laptop as well.

Electrical Storm & your Computer

Electrical Storm can damage your Computers and your Electronic gadgets.


I had a clients who complained that she can not connect to the internet after a bright flash of lightning struck outside their house that night, another one said the same thing though he wasn't using it and his computer was turned off when that happen.   
When i inspected their computers, both clients have the same problem. A damaged LAN card.
Somehow that lightning traveled through the telephone lines and damaged their LAN card even though the other one was turned off.

My advice is, during Electrical Storm you should unplug your LAN cables from your modem to avoid this kind of problem. If you are going out for a trip or vacation, before leaving your homes or offices take time to unplug your cables. Who knows, an Electrical Storm might take place while you are away.

Additional tips when a strom is Approaching:
- Unplug your appliance power cords and cables from outlets
- Lightning can travel through wiring and water pipes, so unplug appliances
- Turn off the air conditioner
- Draw blinds and shades over windows. If windows break due to the wind, the shades will   prevent glass
   from shattering into your home    
- Avoid taking a bath or shower

Warning: 
Computer vendor and Mother
Board manufacturers customize their BIOS to
the individual specifications of the mother
board. Care must be taken when applying a
BIOS update. A BIOS update should be applied
to the exact make; model; version; etc.
specified in the update description.

Applying the BIOS update to the wrong BIOS
chip can render the system unbootable and
could necessitate a Mother Board or BIOS chip
replacement.

PC MEMORY TYPES

RDRAM -- Rambus DRAM

 If you are using RDRAM, make sure that all memory sockets of a channel are filled with either a memory chip or a continuity module. RDRAM often has to be installed in pairs of the same type of memory chips.

RDRAM devices may be configured into single-, dual- or quad-channel RIMM modules. For dual-channel or quad-channel (4-channel) RDRAM chipsets and motherboards, memory module upgrades should be in matched pairs. For instance, to add 512 MByte of memory into a dual or 4-channel system, two matched 256 MByte modules should be inserted.
 Example of RDRAM speeds include PC 800 (PC-800 or PC800) and PC 1066 (PC-1006 or PC1066).

SDRAM -- Synchronous DRAM (JEDEC SDRAM)

SDRAM (synchronous DRAM) is a generic name for various kinds of dynamic random access memory (DRAM) that are synchronized with the clock speed that the microprocessor is optimized for. This tends to increase the number of instructions that the processor can perform in a given time. The speed of SDRAM is rated in MHz rather than in nanoseconds (ns). This makes it easier to compare the bus speed and the RAM chip speed. You can convert the RAM clock speed to nanoseconds by dividing the chip speed into 1 billion ns (which is one second). For example, an 83 MHz RAM would be equivalent to 12 ns.


Example: PC-133 CL2 SDRAM = 133MHz (SDRAM, PC133 • CL=2 • Unbuffered • Non-parity • 133MHz • 3.3V )

DDR SDRAM -- Double Data Rate SDRAM

DDR SDRAM is synchronous dynamic RAM (SDRAM) that can theoretically improve memory clock speed to at least 200 MHz*. It activates output on both the rising and falling edge of the system clock rather than on just the rising edge, potentially doubling output. It's expected that a number of Socket 7 chipset makers will support this form of SDRAM.
Synchronous DRAM speed is measured in MHz rather than nanoseconds (ns). You can convert the RAM clock speed to nanoseconds by dividing the chip speed into 1 billion ns (which is one second). For example, an 83 MHz RAM would be equivalent to 12 ns. 
Example:
PC 66
PC100 = PC-100 DDR RAM was sometimes called PC-1600 SDRAM because of its data bandwidth (transfer capacity) of 1.6GB per second.
*comes in 184-pin DIMM and 200-pin SODIMM formats
PC133
PC2100 (DDR266)
PC2700 (DDR333)
PC3200 (DDR400)

DDR2 SDRAM -- Double Data  Rate  SDRAM 
Example:
PC2 3200 (DDR2 400)
PC2 4200 (DDR2 533)
PC2 5300 (DDR2 667)
PC2 6400 (DDR2 800)

DDR3  
Example:
PC3 8500  (DDR3 1066)
PC3 10600(DDR3 1333)
PC3 12800(DDR3 1600)
