Virus 101

Share Button


Virus or computer viruses are uninvited visitors of a computer unit. Early viruses are self-replicating program that floods the network and usually send spam messages. The first known virus is known as “Creeper” wherein it will send out a message saying “I’m the creeper, catch me if you can!” to the network. Later on, Reaper was created to delete the Creeper virus.

People are usually confused about computer viruses, Trojan horses, computer worms, rootkits, spyware and adware. Here is a short description of their differences:

• A computer virus is a program that can easily multiply and can infect one computer to another and needs to attach itself to a computer program.

• Trojan horses, just like in the Trojan War where the Greeks gave the city of Troy a wooden horse as a gift, with a bunch of men hidden inside. Trojan horses can steal information or harm their host computer systems by disguising as a helpful program which will eventually allow other viruses to infect your computer.

• Computer worm is somewhat similar with a computer virus but it doesn’t need to attach itself to a computer program and it frequently needs a network to multiply.

These three are the major types of Malware (Computer Virus, Trojan horse and Computer Worm)

Rootkit came from the word root plus the word kit. Root refers to the target computer and the word kit is pertaining to the set of tools used to gain access to the target computer with administrative privilege. Rootkit usually hide its existence from antivirus and modifies the operating system to hide the malicious activities performed by the attacker.

Spyware is another type of malware wherein the actions of the computer user is being monitored by a software hidden in the computer. The main purpose of this malware is to collect data and track the user’s activities on the computer.

Adware is the so-called unwanted pop-ups or sometimes a form of advertisement that shows up on your screen. It is somewhat related to spyware for it is mounted on users’ systems without their consent.

As we all know these computer viruses, Malware, Trojans, Rootkits, Spyware and Adware will cause inconvenience to each and every one of us, so we should be very cautious not to have any of these. As they say, prevention is better than cure and the most effective way of avoiding your computer from being infected is proper knowledge and good practice. Keep your antivirus updated! 🙂

Difference between Cold Boot and Warm Boot

Share Button

Ever heard of the terms Cold and Warm boot?  Yep, you read it right, Cold and Warm boot!  Now, let me explain the difference between the two in the simplest way I can.

A Cold boot refers to the process of just simply turning on the power button/switch of your computer after it has been powered off for sometime.  An instance of cold booting a computer is when you turn on the power after being off, let’s say you turned off the computer last night and this morning you turn it on.

On the other hand, a warm boot is restarting a computer that is already turned on.  It is applied in re-opening a computer when a program is not responding or encounters an error from which it cannot recover.  It is also performed whenever a BSOD (Blue Screen Of Death) appears on the screen.  A warm boot can be performed by simultaneously pressing the Control, Alt and Delete keys.  As per experience, the usual cause of these errors is a possible memory problem.  If ever the computer still does not respond after a warm boot, let it rest for a while, then perform a cold boot afterwards. Troubleshooting this kind of issue will be further discussed in my next tutorial series, so please stay tuned :).   A warm boot is also known  as the soft boot.

There you go, 2 simple computer terminologies to add in our computing vocabulary.  By the way, what time did you cold boot your computer today?

Hello! I am JM, a graduate of Bachelor of Science in Information Technology at AMA Computer College.

I love computers and gadgets and I am also a big fan of online and LAN games. I may not be a Tech guru but I am always updated with the latest news and trends in computing and gaming, the reason why was born. Through this blog I would be sharing my knowledge and experiences by creating tutorials, computer tips and tricks and reviews on the latest gadgets and technology.

My interest in computers and gadgets started when I was in fourth grade wherein my very first computer was running on Pentium 3, my foremost handheld gaming device was a GameBoy color and the initial gaming console I own was a Family Computer. I can still remember, before if you have a Nokia 5110 you’re cool, you’re cooler with a Nokia 3210, but having a Nokia 3310/3330 will make you the coolest kid in town along with the acetate and colorful backlight. Can you guess how old am I now? 😀

As the years go by, technology keeps on progressing, advancement gave way to rapid development of the latest gadgets and computers. People are looking forward to advanced and futuristic gadgets, so I’ll be talking more of these so called “new innovations”.


Please join me in exploring the wonderful world of today’s technology!
