Ways they Attacked and Tips to Avoid Being Victimized
1. E-mail:
Hackers use this type of technique to acquire what they need by sending an e-mail containing a link to a site they expect you to input your details they needed at. And, by entering those details, you have become a victim.Avoid Being Victimized
Never click on a link sent to you through e-mail unless you know its destination.
2. Website Forgery:
This method means that hackers will create and design a site that is much more identical to the original site you intend to visit, and after visiting the site and you recklessly input your details, you just did what the hacker wanted.
Avoid Being Victimized
Always check page information (whenever you visited a site that requires you to provide your personal details) to verify the site authenticity or just rest your mouse on a link you wanted to visit for a moment to see if the address matches the link you expects.
3. Phone Phishing:
Hackers might risked to pick a phone to call you and sounds like an IT administrator from the company you are working with and will tell you that something just happened and he/she will like to have your password to be able to rectify the problem.And, they can also send messages that claimed to be from a bank and told their victim to dial a phone number to rectify a problem with their bank account, and, once the victim dialled the phone number, he/she will be prompt to enter his/her account number and PIN.

Ignore every calls or messages you got that requires your password or PIN.
Besides, if bank need to rectify a problem with your account, they will not ask for your password/PIN before they can rectify it.

Is your computer system restarting frequently and sometime after the bunch of restarting, it will boot normally and ends up freezing.
Hi readers! This is not an article but a tip i thought it will be useful for my readers, incase you got the same problem with your system.
When using my computer today, i just noticed that it freezed, then i off it and on it back, and after i pressed the on/off button to on it, what i noticed is that when it was about to boot, it will start restarting itself for some couple of minutes then ends up freezing after it boot.
You know how it will look, right? I was like, how can this happen today and the lame man thought just hook me up that may be i should try and format it, but for me not to loose my documents and some software i downloaded and didn't have back up for. I insert my OS software and instead of formatting it, i ran the repair option, but when the repair was about to start, the system hung again.
That is when my critic try to settle down and my real engineering brain started the work by removing the OS software.
I on my computer and after it boot i saw a short window prompting to send an error report to microsoft.
So, i clicked to view which type of error the system want to send and i saw this code BCCode: 1000000a BCP1: 87f27AC4 BCP2: 00000002 BCP3: 00000000 BCP4: 804DC42A OSVer: 5_1_2600 SP: 2_0 product: 256_1.
After i saw the code, what came to my mind immediately is to remove the CMOS battery to reset it to factory setting but that is not the solution.
The solution is just that, i opened my computer case and remove the two memory card from their slot.
After i removed the two memory card, i started by the first memory card by cleaning it and re-fixed it to is slot. Then, i pressed the on/off button to on the computer but it end up freezing. I removed it, i cleaned the second memory card and fixed it to its slot, then on the computer and the problem solved and i started working on my system again without any error.
That's just it, hope it help?

Sometimes, we have money to purchase a new computer (desktop/laptop) with us but contemplating on which computer (desktop/laptop) to buy.

Business and Gaming laptops comes with lot of memory, good screen size and medium weight. As the name states, it is suitable for business and gaming purposes.
Desktop replacements are well suited for the computer users who plan to move their computer some of the time. This type of laptop comes with larger screen and big memory which could replace the functionality of a desktop computer.
Windows (7 or 8) laptops are more affordable and offer a wide range of choices from major vendors. Also it provides business friendly features like biometric and smart card verification.
Mac is the operating system from Apple which is easy to navigate and use. Mac OS X Lion is the latest version of mac and it has advanced technology features.
But we have various sizes of memory e.g. 1gb, 2gb, 4gb, 8gb e.t.c. So when purchasing a laptop 2gb is the least recommended size of memory a computer must have before purchasing it.
So i recommend back up of at least 3 hours of durability.
Graphics cards: ATI or NVidia offers graphics chip for better video and 3D graphics performance. Intel also deals integrated graphics hardware for games and HD video playback.
