Data extraction is a very complex and delicate process as in this process professionals only get 1 or 2 chances to recover files.

Types of Recovery :
Software Recovery:
·       Deleted Data – This is usually done by very expensive advanced processional Software which is  able to scan and read sectors on drive which were deleted.
·       Inaccessible/ Lost partition - In this case data is on the storage drive but is not accessible.

·       Logic Board Failure – This happens when the circuit board on HDD is not working or HDD cannot be turned ON. It is not easy to perform this kind of recovery as HDD need same exact same logic board from same manufacture and model of the hard drive.
Should I attempt to Recovery Data on my own?
Yes if you definitely don’t want your data back then go ahead and try it. Recovering data by users on their own is not recommended by Mac Hard Drive Recovery HK at all, if you do so then you will be the one destroying hard drive plus any possibility of recovering data by professionals.

Is Windows & Mac recovery same?
According to Macbook data recovery Hong Kong it is important to understand that windows and mac both are using different file systems. Windows hard drive is formatted as NTFS whereas Mac uses HFS+. That’s why software recovery of both the systems is performed in different way using different typed of recovery program.

·       When your mac OSX is not booting up then do not force boot it or turn it OFF & ON multiple times as this will lead to complete HDD failure.
·       If your camera memory card is not readable just take it out and leave it. Don’t try inserting it in other devices as it reduces recovery chances.
·       Never attempt any kind of recovery on your own.
·       Always keep a backup copy of your data no matter what device you are using.
·       If your hard drive is making clicking sound that means it needs hardware recovery so never attempt to open it physically.
·       If you have deleted data by mistake then right away turn OFF your computer and don’t use it unless data is recovered. If you do so you will be overwriting sectors and recovery will be impossible.

Data recovery is a very complex and time consuming process and it requires highly skilled engineers to extract files from damage drives so it will be always an expensive process no matter which device you recover. Data Recovery Hong Kong Whenever recovery is required of files such as photos, music, videos do not attempt to recover on your own and always ask for professional help.

What to do in case of Liquid spill on Mac? Spilled Liquid on Macbook Repair Hong Kong

Every day we receive many Macbooks being damage by liquids like coke, juice, sodas, coffee, tea or other kinds of party liquids like Beer, Whiskey, Cocktails or plain water. Many customers ask us what to do in case of liquid damage as they have already damage their machines so it’s too late to explain procedure. Now you can know the procedure to save your macs in case of liquid damage before it is too late. 

What happens when liquid spills on mac? Do liquid spill really damage laptop? Why computers don't work after liquid spill?

Usually liquid wont damage your computer right away in fact most of the macs are damaged by actual user itself and not the liquid. What we have seen is after spilling liquid every person tries to turn on their macs or if it is already on they don’t turn it off instead they run around to get tissue or towel to dry it.

Mac Liquid Spill Repair Hong Kong will tell you step by step procedure what to do in case of Liquid spill but before that you must know what kind of liquid you have spilled on computer. We have divided liquids in 3 types of categories:

1.     Sugary drinks/Sticky Liquid - These are liquids that are sticky in nature due to presence of sweetener or sugar inside. These liquids always damages keyboards, trackpads and are most dangerous kinds of liquids e.g. Juice, Sodas, Coffee, Hot Chocolate, Milk etc.
2.    Water base Drinks - These are drinks that are mixed with water. These may or may not have sugar inside so they are less dangerous like Green tea or Chinese tea.
3.    Alcoholic Drinks – With this category people have wrong assumption that alcohol does not damage computer but actually it does as they have water or sugar inside like beer, vodka, whiskey and Pinna Colada which girls always spill :) 

Now as you are familiar with categories of Liquids so we can proceed to procedure of saving mac. Computer Repair Hong Kong will tell you what to do in case of Liquid Spill in the procedure below.

The Procedure

  1. 1.   DON'T TURN ON YOUR MAC. If it is already ON then hold down power button for 5 seconds to power it off.

    2.    Remove any charger or battery connected to your mac. MacBook’s where you cannot remove battery DO NOT ATTEMPT TO OPEN Just leave the battery inside.

    3.    If the liquid went onto your keyboard then flip the computer upside down (see picture) and keep it at the corner of the table in same position so liquid can drain out and this will prevent liquid from entering further onto logic board.
    Leave it in that position overnight if you spilled liquid  at night. If in Daytime then bring it to MacWin Technology immediately as our Water damage experts will clean your mac and save it from damaging completely.

    4.    DONT USE HAIR DRYER - Every person tries to use hair dryer as they think it will dry out the liquid but instead they end up burning the vital logic board components and specially keys on the keyboard. Using hair dryer will not dry the liquid that has already entered mac no matter for long you dry it. 
    Another reason not to use dryer is, everyone after blow-drying try to turn ON their computer and that’s when the board blows off.

    5.    Bring your computer to Liquid damage repair Professionals and not to any computer store as most of the cases technicians don’t know how to deal with liquid damage boards and they try to clean the board with various Chemicals. We have also seen cases where technicians attempting to turn ON macs in spite of knowing it is liquid damage.

    Take your computer to repair store ASAP as this really helps in saving logic board. This is the most important STEP as cleaning internal components saves it from rusting.

Dos and Don'ts

  • Do not turn ON your mac at any cost before you take it for repair.
  • Remember you spilled a drink be ready to pay for it and accept your mistake, don't try to save few dollars on cleaning and don't try to do things on your own as 99% cases it gets worst.
  • Bring your mac to Macbook Repair HK at earliest possible as in that cases damage will be minimum.
  • Some cases people just turn on their mac after spill and it starts working and they think OK nothing happened. We have seen cases where people used there mac for 2 days and then suddenly board or screen blows off. Don’t think it is working now and nothing will happen, you must not turn it ON. Liquid stays inside and will move around, secondly it starts rusting board components so take it for cleaning immediately.
  • Keep tissue on keyboard while carrying your mac to a repair store as it will absorb all extra liquid while your mac is moving and also it prevents screen from being damage.
  • Do not use any chemicals or house hold cleaning liquids to clean your Mac.
  • Do not follow instructions online and videos to open and repair your mac yourself. Remember professionals know what they are doing and this there daily job so let them do the things in right way.

Follow the steps provided by Water Damage Laptop Repair HK and your mac will be fine. Remember never turn ON liquid damage computers and must seek for professional help immediately. Contact MacWin Technology Hong Kong (852) 64037272

How To Hack Anyone’s password – Using Keylogger Program

In our previous post we told you How to identify Keylogger program and ways to block or remove it. In order to identify Keylogger it is also very important to know how Keylogger program actually works or how to use this program.

Keylogger - What’s that?

It’s spying software that records each and every Key stroke a user types on a target computer in a log file. This log file is send back to owner via email or uploaded on FTP. This program can be installed very quickly and starts working immediately. It records all sensitive information like email ID, password, credit card no. etc.

How does Keylogger Work?

Once Keylogger is installed it will run in background in a hidden mode so victim won’t see any unusual activity on his computer nor he will able to find it in control panel or installed programs. This program starts automatically when vitic turn of computer and starts recording every key strokes as soon as victim types. Suppose victim logins to hif Gmail account then Keylogger will record that was types and IE was opened. Then it will record his user ID and Password.

Advanced Keylogger also records screen shot which is also quite helpful to understand victim’s system environment.

Keylogger – How To Use?

Keylogger are very simple and easy to use. Anyone with basic computer knowledge can use it. In order to use Keylogger simply download a good Keylogger  programs ( Search Online) or you can choose to have free Keylogger.

After downloading if you have physical access to victim’s computer then simply install Keylogger on his machine just like normal program and configure it to send log to your email.

Remote Installation -
If you do not have access to victim’s computer then you can send him keylogger file remotely. Just install Keylogger on your machine and create remote installation module. 

Mostly Keyloggers will have feature where you can attach this module to any picture. You can send this module to victim via online chat or email (for email use .rar or zip). As soon as victim open up your attachment he will see the picture file on his screen but in background Keylogger will install silently and start doing its job J
Keylogger runs in full stealth mode so there will be no window popping up plus it will never be seen in start menu, task-bar programs or control panel.

Conclusion: There are Key loggers for Mac and Windows both and if you are using good antivirus and AntiSpyWare program then you won’t get infected.

Easiest way to steal someone’s Password - Keylogger – How to protect?

Keylogger are the most common software used these days to hack someone’s email password, identity information, credit card details, and many other important login Passwords. Keylogger are very easy to use program and even a primary school kid with basic computer knowledge can use it to hack your computer. Surprised? Furthermore Keylogger can also be installed remotely through other computer so person sending you Keylogger program don’t need physical access to your computer and most important it can also be attached to any picture so when a Victim opens picture file he won’t even know Keylogger is installed in background on his computer. 
So how to protect your computer against these Keylogger? We will tell you some Good ways to be secured J
First you should know what a Keylogger is? Keylogger is a program that records every key stroke of your keyboard as you type. So when you login to your email or when you make online purchase all the password and numbers you type are recorded in a log file and automatically sent to actual owner of Keylogger. Keylogger programs are also capable of recording screen shots and mouse clicks.

Ways to protect your computer -

1. Install a Good Antivirus Program

Installing good Antivirus is first and most important step. Do not compromise on Antivirus program and never buy antivirus software based on cheapest Price.
There are so many Antivirus software in market which one to buy?
To get the answer you can ask our hacking professional who keeps testing all new Antivirus software’s every month and suggests best and reliable software. Let experts at MacWin Technology build your system security so your computer is well protected. Mac users don’t think your system cannot be infected or Mac cannot be Hacked. Always make sure your antivirus program is up to date. All good antivirus programs can detect most common Keylogger.

2. Antispyware – Another most important program

Now you must be thinking if I have Antivirus software then why do I need Antispyware?
Well Keylogger is considered as spyware and not a virus and not all antivirus programs are capable of catching spywares. Spywares Algorithms and behavior is completely different from a virus. A spyware is meant to steal information and they are programmed to doge Antivirus programs. Antispyware reads programs behavior and they don’t work on same basics as Antivirus. In today’s date Antispyware is more important and must program than a Antivirus. Most Antivirus software has AntiSpyWare function but most of them are useless. We recommend Pc Tools Spyware doctor.
Apart from these other methods by which you can find Keylogger are:

3. Scanning file online

If you receive a file from some untrusted source and if you are not sure about file security then another good free option is to scan file online. There are many free online scanning websites where you can upload file and run a free scan. Usually these online scanners use more than 20 different popular antivirus programs to scan file and they provide you full report about file security. Good free online scanning website is Virustotal

4. Using a Antilogger Program

Most of you guys may have not even heard of Anti logger program. Antilogger is a program that is made to detect Keylogger in a system. Usually all good Antivirus software’s will detect Keylogger but advance hackers will use technique like Crypting and Binding to doge antivirus programs. We have tested many Antiloggers and we recommend Zemana Antilogger.

5. Using Key Scrambler

Key scrambler is a program that encrypts all your keystrokes when you type so even if a Keylogger manages to doge your antivirus program it still cannot record key strokes. Keylogger installed on your computer will record encrypted key stroke scrambled by Key scrambler and not originally typed keys stokes. Keyscrambler is free utility for basic protection. You can download and use it on a public computer for further safety.

Conclusion: Keep your computer fully secured and scan regularly and if you are not very good with computers then you can ask for experts help at Computer Repair Hong Kong.
