Malware can attack multiple ways. The technology (spyware, trojan, rootkit) and the attack vector (fake software, e-mail attachments, direct hacking) has remained the same.
It's the intent that is different, malware always has some type of fraud behind the purpose of distribution.
Some examples of how malware works
Trojan Horse
You download a cool calculator program and install it. The calculator works fine. In a few days you start to have problems with your computer and when you search on the internet you start to get annoying pop-ups. Then you start to get popups at random when you are not searching the internet. The malicious pop-up program was most likely hidden away inside the calculator program. The installation also may have implanted itself inside programs that already existed on your computer. This makes it difficult to remove.
Rootkit in e-mail attachment
Your friend sends you a funny video, when you double click on it you get a security warning, but you want to see it so you click OK to get past the warning. However nothing happened, you think nothing of it..maybe it was a bad copy.
Later you talk to your friend however he says he didn't send you a video. Something did happen in the background when you clicked on the video, malware was installed. There is no way to know the intent behind it. You may not notice anything, your computer could be used as a bot net drone to attack web sites or other computers.
Spyware in "drive by download"
You click on a link in search results and immediately get pop-ups. You close the pages but get weird errors. You think nothing harmful could have come of it, you simply "drove by" the website. You didn't install anything. However your computer had a software flaw that let the website install spyware without your permission. You didn't get a warning because it was a flaw in the programming of the web browser. You now have spyware resident on your system. What you type in web forms, login pages, chat and what sites you visit could all be sent to the hacker's website.

Malware can be very harmful to your personal computer so firstly you need to scan your PC frequently with a strong virus detector such as AVG or Avast to see if the threat still remains, then to be on the safe side, I would strongly recommend an anti-malware software, specifically designed to get rid of dangerous malware. The most popular is Malwarebytes Anti-Malware. It's also important to back up your files regularly in case you happen to encounter a virus that got into your computer before you had any anti-malware support or was able to hijack your computer via the Internet. In the case that you didn't back up your files and you don't want to buy a new computer or sacrifice all your important files, (eg. pictures, documents...) there are programs that are specially designed to cure certain viruses, provided that you know the name and/or problem.
Why do you need to study science and technology?
We are at the age were technology is the one spinning the world. All of the things that makes our lives comfortable nowadays; from the tiniest microscopic robot doctors to enormous space shuttles going to the unknown space in search for information are made through technology. Technology is science is the application of the sciences. Centuries of researches and countless ideas made every technology that we are enjoying today.
We need to study technology mainly because of the important role that it plays in our lives. Without it we would still be living in the Stone Age. Without it centuries of hard work and enormous research activities done by several intellectual men and women will be put to waste because as we all know facts and theories alone will not directly be of help to us. Technology plays a vital role in almost every aspect in the society. It gave birth to cellular phones, telephones and other ways of making communication a lot easier; thus making distance not a hindrance in business and trades. Medical milestones were also achieved through the use of technologies like powerful microscopes, scanners and robotic equipments that made procedures impossible to men not long ago doable today. The computer and its various types that are everyone's best friend nowadays are also one of the greatest children of technology. Computers not only boosted the business process but also mobile. You can do business almost anywhere as long as you have your laptop at your side. Computers were made to be very versatile and can be of use from gaming, sports, sea navigation, simulations, and other things beyond your wildest imagination. Technology also gave breakthroughs in building and road constructions. The development of high grade cements made it possible to make skyscrapers and bridges that literally crossed oceans. To sum it all, technology is like a virus that infected our society. But unlike typical viruses, this virus is not harmful unless used in wrong ways.
It has been said by some analyst that men will destroy themselves in the future. That the genius minds behind the different technologies that we are having today will soon create a community that will destroy themselves in search for power and greed. In my opinion technology will have a great role in the continuing existence or the destruction of men. If technology will be used properly, our society will benefit from it and man will continue to exist and face the challenges that time brings but if technology will be abused then we are like making the sharpest knife just to stab our own heart.

Has anyone been prosecuted for using LimeWire?
It is not illegal for anyone to use Limewire. It is simply illegal to download copyrighted files on Limewire, and the only people who may be charged for this is the original downloader. When other Limewire users download the existing file, it is simply called "file sharing," and it is most definetly not illegal.
Soooo....no, no one has been prosecuted for using Limewire-just for downloading coyrighted files on to Limewire. If you aren't copyrighting anything, you have not broken the law, and have simply participated in file sharing.

The 2o7 cookie is a tracking cookie which registrates the sites you visit on the net. It invades your privacy and who know what else.
More Information:
I found what appears to be legitimate websites. There were many queries about 'cookie 2o7'. My security always catches it. The address used is my username on my web mail. They, as with many other tools, legit or otherwise, use MSN to validate their existence. I have no evidence to support the 'virus' theory. Their ISP is 207.112.xx.x I do not know all the nrs. But that is what is on 'Bing'. I do not go past the webpage. I simply do a windows scan with my security daily. My whole computer, including hardware, weekly. I also compress my disks and clean the temporary files, recycle bin, etc. I have seen problems created to sell tools. Some through 'insider trading'. I just keep my computer clean, my DSL clean, use 'in private', filter 'lock block', and try to remember no one 'gives anything away', sometimes a lucky deduction from a big corporation may fall to the end user.
I had big problems with this cookie 2o7 until I did this:
click on Tools\Internet Options\Security Tab\ Restricted Sites\
Then click on 'Sites' and then in the box that reads 'Add this website to the zone:' type in *2o7.net
And no more cookies from them! Hope this works for you too... Remember its a lower case letter 'o' not the zero '0' - in 2o7.
What protects a spacecraft against overheating upon re-entry?
On the space shuttle, there are a number of protective devices, but the most obvious are the insulating tiles. These are made of various materials, but mostly from a silica based insulation with ceramic coating.
See the Web Link to the left for more information, but note that it predates the loss of Columbia from damage to tiles at a vital position on the orbiter.
In earlier space programs, the spacecraft were protected by a shield which actually partially burnt away as re-entry progressed, thus taking away the heat from the craft.
