have never made any online purchases using a credit card before because it isn’t an ideal way for me to deal things & I don’t have friends that purchase items on the Internet using a credit card too. I feel that it isn’t ideal based on the some of the points that I’ll state but there are other negative points.

1. A big disadvantage of online shopping is that we do not see the item physically till it arrives and it might have a defect on it.
2. We all know that it takes a few days for our items to arrive after our payment. Hence, we might be excited about the item that we bought for the first few days before it arrives. But we might be less excited then compared to the day when we bought on that day we made the payment.
3. There would also be shipping charges applied but there are also some websites that offers free shipping. This is considered a bad point if we want to save money buy purchasing items online.
4. If you computer is infected with a spy ware. People might get to know your particulars and your personal data like example your credit card information but we cannot put the blame on the sellers.
5. There are risks of online fraud too.

One of my friends had encountered a click-jacking virus before & I managed to help my friend fix it by following the steps in the following website http://www.cyberciti.biz/tips/firefox-stop-clickjacking-attack.html . I’ll explain what I understand about it. A Click jacking virus, or click jack attack, is an attacker to collect an infected user’s clicks use vulnerability. The attacker can force the user to do all sort of things from adjusting the user's computer settings to unwittingly sending the user to websites that might have malicious code. Also, by taking advantage of Adobe Flash or JavaScript, an attacker could even place a button under or over a legitimate button, making it difficult for users to detect. A virus scanner might be useful. I personally advice you guys to get the best virus protector which is Bitdefender and I am using it myself too. It is rated as one of the top virus scanner. It slows down your computer at times as it is updating and occurs especially during start up. Just have a scan once a month and it will help a little.

Click jacking is essentially hijacking a click. This means that you will think that you are clicking on one thing, when in reality you're clicking on another. This probably doesn’t sound like much of a big deal on the surface, until you consider that you might think you’re clicking “submit” on your bank’s website, and really you have just given your username and password to somebody who plans to drain your account in the next five minutes.


The real sticky widget in this situation is that you could be clicking a button that looks completely normal and is even on a completely legitimate site. You can actually be on your bank’s website and still get click jacked.

But luckily I had never encountered click-jacking viruses neither my friends.

One of my friends had made an online purchase with his father’s credit card before as he had not enough cash to pay for the goods that he wanted to buy. He got scolded when his father realized that.


I personally feel that online purchases are not very secured as Internet scammers have been working very diligently on new and more interesting ways to separate you from your money or information. So, I would rather purchase goods from shops than purchase them from online.

No, I have not encountered a click-jacking virus before but I know a friend that had encountered it before. He clicked it as he thought it was a link that was sent by his friend.


Click-jacking is able as it seems harmless features of pages can be used to perform unexpected actions.

A click-jacked page bluffs a user into doing undesired actions by clicking on a concealed link. On a click-jacked page, the attackers show a set of dummy buttons, and then load another page over it in a transparent layer. The users think that they are clicking the visible buttons, while they are actually performing actions on the hidden page. The hidden page may be an authentic page, and therefore the attackers can trick users into performing actions which the users never intended to do and there is no way of tracing such actions.

These are the things that I know about a click-jacking virus.

Yes, I have received spam emails very often. But usually I ignored them as they might have contained of such dirty stuff or viruses. I do not bother about spam emails because I am afraid that my computer would have some technical problems. It is sad to say that I have a friend who clicks on this “email” and unfortunately for him, his computer has virus. I felt sad for him and I felt so useless because I could not be of any help to him. Fortunately for me, I am not an internet addict. I do not even want to be an internet addict as I am afraid that it would affect my grades. I think that those who spam the emails should stop because they are only harming the other people. They should think twice before spamming the emails like me.

Luckily for me I had studied the benefits of cyber wellness.
