Money management
It is possible that, when trying to save some money, you actually end up spending more than you would have needed the first time. This is the equivalent of not doing something when it needs to be done, but rather when we choose to do it.
If your computer is clearly showing signs of distress, this is called feedback. You must not ignore that, as it gives you a head start into doing whatever is necessary to prevent any real damage. Choosing to ignore that, may lead to loss of data as a primarily consequence. All your pictures with your family and friends could be lost, all your important documents from work and so on.
 
Core safety
The most important thing will never be your computer, but the data it has stored in it, so you must always back up your data. CD\DVDs\USB sticks are cheap to buy so don't hesitate into using them for backing up your files.
You should buy CD\DVD\etc. only from important manufacturers. These days you can buy a DVD from the grocery store, made by that store and this is not always the best solution. When it comes to saving data, it is wise to use the proper tools.
 
Discipline
Basics task, like scanning disks for errors, defragmenting and cleaning the registry, are just some of the things you need to do, from time to time. Ask someone qualified for help if you feel you need it, but do not ignore them indefinitely.
 
Prompt decisions
You must also remember that, though there are many "best offers" when buying a new PC, you should be accompanied by at least one person who really knows something about computers and will help you choose what is right for you, at the best value. A salesman will try to sell you just about anything, because that’s his job. Your job is to know what you want to buy and not take the bait from anybody.
The best computer on the market is not necessarily what you need and there might be other pc's, cheaper, which could do the job just as well. It all depends on what you are using it for.
 
Flexibility
Windows is not the only operating system. Linux is also reliable, virus-free, stable and of course, free of charge. You could try Ubuntu Linux if you ever get the chance or any other version of Linux.

Safety first                                          
Shopping online is a common thing today, but with every transaction that you make online, you expose your entire card details, even if you have set up you pc to be safe, with firewall, antivirus, etc. Furthermore, most of the websites will tell you that your transaction will be processed on a secure webpage and you can see that by the yellow colour from the address bar.
Unfortunately, while this is a good security measure, it is not flawless and cannot guarantee that your card details are safe. Thieves use, among other things, web scanners which can detect and gather all details of a transaction, thus enabling them full access to that account.
The best solution is to use PayPal. This is the real protection for your bank details, as it will never display your card details and it is widely accepted as an online paying method.
Furthermore, never give your card details to e-mails that ask you to do that. Nobody will ever ask for your card details through e-mail, except a thief. This is a fact.

Popups
Pop-up ads or popups are a form of online advertising on the World Wide Web intended to attract web traffic or capture e-mail addresses. It works when certain web sites open a new web browser window to display advertisements. (source: Wikipedia)
In most cases, popups can be translated as: undesired adverts which can act as a door for Trojans, Malware, Viruses. Use popup stoppers to disable them and ensure a safe browsing.

Wonderland
Websites can be cloned, even banking websites, with perfect details. The only difference is the site address. If you end up on a website of an important company, let’s say a bank and you realise it has a different address than the one you know, it is advisable to stop browsing and call that bank and ask them to confirm their website address.

Insert card
You probably already know, but cash machines are not safe. If you see something suspicious on any of them, DO NOT insert your card and report it immediately. Some people can attach small devices on cash machines to record all details of every card used and then they can replicate that card, using card making machines. Try using the cash machines inside the banks, which are safer.

Congratulations, you have WON!
NEVER trust adverts that say you have won a lot of money and all you have to do is click for details. Never fall for that. It is an ancient, yet effective method to make you enter your bank details or to send money to an unknown destination. Nevertheless, a lot of people still fall for it, which makes it really bizarre. Being gullible has a price.
You will never win without playing first. And if you ever win something, NOBODY will ever ask you to send money first of fill in your bank details, except a thief. Fact.

Become instantly rich
The saying: “if an offer looks too good to be true then it generally is” has never been more real than now. So many cons pretend they know an efficient method to make money quickly and legally and all you have to do is pay some money in advance. These tricks are old as time but they continue to work because they usually reach honest people who are easily misled into guaranteed ways of losing their money.
Here’s an example: some websites say that you can make loads of money by playing online Casinos, using a secret method.
They are sharing this information because they have found a flaw in the roulette system of those casinos and they’ve made a fortune and now they want to share the information. All you have to do is go to that casino’s website, create an account and play by the method they describe. Furthermore, you can also play for fun, to test the method, without investing money.
After you’ve played for fun and you realise the method works, you decide to put some money on, because you’ve seen it’s real. You win a bit, but eventually lose everything. It all depends on how much you invest. They are also giving you money bonuses for you first deposit and everything sounds so perfect...
Many people do that and in the end, not only they lose their money, but that casinos make a good profit out of them.
Here’s why you will lose, if you follow their instructions:
1.    The demo that you’ll play is not as the real game. It is easier and you win there more often than in the real game.
2.    They say that if you bet a small amount, on the same colour, over and over again, you will win, but they do not say that you can hit the 0 on the roulette (and you will hit it). You could bet on red, for example, 10 times in a row, and still get only black.
Online casinos are a good place to gamble and you can win money, but not by following “secret methods” of various websites that look suspicious from a mile away.
This only attracts more customers to the specified casinos and nobody can accuse them of anything, as they have no direct connection to those fake websites.
Simply put, more and more fake offers sound genuine but they always have a flaw, which unfortunately is not easily discovered. Always remember this:
