When you connect to the internet you can harm your PC. That is a fact. The reason antivirus software and other similar products where created is to protect your PC.
It is not your fault that you got viruses, however you should take the precaution methods to stop this from happening again.
Keep PC Clean: It is important that your PC stays clean if you use the internet. Clean from the 'bad, harmful objects' that are also known as spy ware, adware or viruses.
There are many different types of harmful objects but luckily there exist also cure to keep your PC protected.
A must use Software: The two most important software you must have are an antivirus and an anti adware. There is no need to purchase 30 different kinds of anti spy ware software...
However you must choose two software which will protect your PC. These will work in the background automatically. Some anti adware products also heal spy ware not just adware.
Schedule Maintenance: The software will block spy ware and adware. However you should also use the software when you are offline. You should scan your
PC using both software at least once every three weeks. That will clean any harmful objects. These objects can make a lot of harm to your PC.
Safety Measurements: We already mentioned that you need two software to keep ongoing protection on your PC.
If you download software/movies/images/videos or any other thing from the internet it is recommended that you scan those items. Before opening them right click on them and use your antivirus to scan them.
Go to Control Panel to turn on Firewall. Firewall is also an ongoing protection which is very important.
Once you have your software installed these protect your PC and you get back the freedom you deserve. Remember that prevention is better than cure.

Tips For Save Your Printer Ink
Buying a printer is a one time cost, but since printer ink cartridges need to be bought on a regular basis, the cost to operate the printer and maintaining it in proper condition can be expensive. Each ‘print’ command, however small, makes your printer use ink, but with some easy tips, you can more save a lot of ink and use a cartridge for a longer period than usual.
1. Print only if you need
Let’s begin to thrift. Most often, we end up making unnecessary printouts and in the process waste precious ink. For instance, you might need to print only a small portion of a web page instead of the whole page. Instead of simply printing the whole page, complete with its heavy graphics etc, be specific on what you want to have in hard copy and print only that portion.
Text always consumes less ink compared to graphics or images. If textual information is all that you need then you can make sure that you don’t print the graphics and images. If it is a web page you need to save in a printed form, check for its print version. If there is no print version, you can copy and paste the text in a word document and take a printout of that.
Also try to do a bit of planning and double check what you are printing before hitting the print button.
2. Check quick to print preview
almost printers like as HP, Canon, Dell, Epson or any other printer come with a printer driver which has a very useful print preview function. It's very usefull, you can have a prior preview of the copy you want to take a print out of.
This function is especially handy when you are directly taking the print out from the Internet. At times, what you see on a site is totally different as compared to the printed version. A quick preview can help to get the printout of the material that you specifically want.
3. Don't forget to turn off
Like as you never switch off your computer without properly shutting it down, the same rule applies to your printer too. If you don’t shut down the printer properly, the print heads will remain directly exposed to air causing the ink to dry in the nozzles which, in turn, could affect the quality of printing adversely. Make it a habit to check the position of the print heads before cutting off the power.
4. Use a software exactly
There are many kind of ink saving software options available on internet. These software applications are designed to reduce the consumption of your printer ink. With these applications, you can get good quality printout copies with less ink consumption even during high resolution printing.
5. Use printer ink cartridges smartly
If you don’t do printing regularly, run a small printing test at least once a week, to avoid the ink cartridges from drying up. This little precaution will help you to increase the life of the cartridge.
6. Never expose your printer to extreme temperatures
Too much variation in room temperature is bad for printer ink cartridges. You must avoid keeping your printer in too hot or too cold a temperature as the cartridges can dry up. For lasting printer performance, make sure the room has a normal and stable temperature.
With these small but important tips, your printer ink cartridges will get a longer life. It is easy to buy good quality printer ink cartridges at excellent prices from online shops.

Process Wireless Network
Wireless networks use radio waves instead of wires to transmit data between computers. Here's how:
The Binary Code or called biner: 1 and 0
It's well known that computers transmit information digitally, using binary code: ones and zeros. This translates well to radio waves, since those 1s and 0s can be represented by different kinds of beeps. These beeps are so fast that they're outside the hearing range of humans.
Morse Code: Dots And Dashes
It works like Morse code, which is a way to transmit the alphabet over radio waves using dots (short beeps) and dashes (long beeps). Morse code was used manually for years via telegraph to get information from 1 place to another very quickly. More importantly for this example, though, it is a binary system, just as a computer system is.
Wireless networking, then, can be thought of as a Morse code for computers. You plug in a combined radio receiver and transmitter, and the computer is able to send out its equivalent of dots and dashes (bits, in computer-speak) to get your data from here to there.
Wavelengths And Frequencies
You might wonder how the computer can send and receive data at high speed without becoming garbled nonsense. The key to wireless networking is how it gets around this problem.
First, wireless transmissions are sent at very high frequencies, which allows more data to be sent per second. Most wireless connections use a frequency of 2.4 gigahertz (2.4 billion cycles per second) -- a frequency similar to mobile phones and microwave ovens. However, this high frequency produces a wavelength that is very short, which is why wireless networking is effective only over short distances.
Wireless networks also use a technique called "frequency hopping." They use dozens of frequencies, and constantly switch among them. This makes wireless networks more immune to interference from other radio signals than if they transmitted on a single frequency.
Internet Access Points
The final step for a wireless network is to provide internet access for every computer on the network. This is done by a special piece of wireless equipment called an access point. An access point is more expensive than a wireless card for 1 computer, because it contains radios capable of communicating with around 100 computers, sharing internet access among them. Dedicated access points are necessary only for larger networks. With only a few computers, it is possible to use 1 of them as the access point, or to use a wireless router.
Industry Standards
Wireless equipment from different manufacturers can work together to handle these complex communications because there are standards which guide the production of all wireless devices. These standards are technically called the 802.11. Because of industry compliance with these standards, wireless networking is both easy to use and affordable today.
Wireless Is Simple To Use
If all this talk of frequencies has you worried -- relax. Wireless networking hardware and software handle all of this automatically, without need for user intervention. Wireless networking, for all its complicated ability, is far simpler to use than you might expect.

Ways To Stop Spam
Yahoo and Hotmail provide this feature in order to keep your private email address strictly for your friends and family members and only. The secondary address, you can use for your subscriptions and other purposes. If your secondary address is abused from spammers and your inbox is filled with spam messages, then you can delete it and create another secondary email address.
Use the Spam arrest service.
When you signup for Spam Arrest, you will receive a spamarrest.com email address. You can also protect your existing email accounts by forwarding them to your Spam Arrest email address, or by having Spam Arrest periodically poll them. In that way over 90% of your spam messages will be filtered.
Use your e-mail’s filters.
Almost all email applications have this feature. You can create filters blocking spam words like “make money, opportunities, Viagra, e.t.c” .Doing that, you will block many of your spam messages but not all of them.
NEVER post your email.
Don’t post your email on forums, websites, message boards, guest books and other online places. You should also avoid posting your contact email address on your website. Spammers use software robots and extract email addresses from thousands of websites. If you want to display your email at your website change it to jpeg photo with Photoshop or other image design software.
The use of email blocking tools.
Yahoo for instance has this excellent tool which can block up to 500 email addresses (the Free option, the paid one provide more) and this amount of spam emails will never reach your mailbox. Other web mail services provide similar features too.
The preinstalled filter in your email application.
If you use outlook express you can click “message” (from windows 98 versions and later) and then click “Block sender”. Just doing that you will block many of your unsolicited emails.
Do Not respond to spam at all costs.
When you receive a spam message which asks you to click a link for whatever reason (fake unsubscribe and other) do not click it. If you do that, the spammers will now instantly that they deal with a real email address.
Do Not Ever open unknown messages with attachments.
This is critical. Most of the times the attachment will be a virus (especially if it’s exe or zip format) If you open it you will activate the virus it contains and harm your computer. Accept email attachments ONLY from well known resources such as friends, business colleagues e.t.c. You should also have installed an antivirus which scans your emails before they are saved into your hard drive.
Excellent tools and resources to fight spam are these below:
