On occasion you will need to edit the hosts file on your machine. Sometimes because of an attack or prank, and others so that you can simply and freely control access to websites and network traffic.
hosts files have been in use since ARPANET. They were used to resolve hosts names before DNS. hosts files would be massive documents used to aide the network name resolution.
Microsoft kept the hosts file alive in Windows networking which is why it varies very little whether used in Windows, OS X or Linux. The syntax stays mostly the same across all platforms. Most hosts files will have several entries for loopback. We can use that for the basic example for the typical syntax.
The first part will be the location to redirect the address to, the second part will be the address that you will want to redirect, and the third part is the comment. They can be separated by a space, but for ease of reading are typically separated by one or two tabs.
127.0.0.1 localhosts #loopback
Now let’s look at accessing the hosts files in the different operating systems…
Windows 7
To access the hosts file in Windows 7 you can use the following command in the Run Line to open notepad and the file.
notepad c:\windows\system32\drivers\etc\hosts
Once notepad is open you can edit the file. In this example we will block Facebook. To do this just enter in the following after the # mark.
0.0.0.0 www.facebook.com
Now that you have edited your Hosts file make sure to save it.
Now notice if we try to access Facebook in IE we can’t get to the page.

With new threats and Viruses arriving on daily basis it is necessary to maintain replace subscriptions and obtain virus definition updates as quickly as they grow to be available.
There’s a lot of good antivirus software program accessible, each free and for low cost. I’d recommend going for paid software…you simply by no means know when you’re going to have to call a helpdesk and that’s usually the difference between the free stuff and the stuff you pay for. Norton, McAfee, AVG and others all sell antivirus software program that is inexpensive on a low budget.
FIREWALL
A firewall is always advisable to assist shield towards unauthorized access to your PC. For a small number of PCs a software firewall is usually greatest and is the simplest to work with when you’re not an IT expert. Nevertheless, don’t low cost hardware firewalls, especially when you have a community with a lot of gadgets on it.
Whatever you do, do not rely on the Community Handle Translation or packet filter built in to your ADSL or Cable router. It almost actually will not be enough.
If you’re buying a specific company’s Antivirus software it’s value considering shopping for their built-in AV and firewall package deal if they have one (if they don’t then perhaps it’s best to strive someone else). It might effectively prevent money and be simpler to configure and maintain.
ANTI-SPYWARE SOFTWARE
In case you spend a whole lot of time looking the Web (and let’s face it, who does not?), then spyware and adware goes to search out its way onto your machine. Numerous it is not particularly nasty, but the really dangerous stuff can ship necessary data like passwords, bank particulars or credit card numbers to people you actually don’t wish to have entry to that stuff. At the very least it could actually slow down your PC and because you didn’t ask for it within the first place then it is best to do away with it.
Some inform-tail indicators that you’ve a Spyware an infection are:
– You’re getting pop-up adverts all the time
– Your default homepage or other settings in your browser all of the sudden change (especially if you cannot change them again)
– Your laptop is gradual (there could be other reasons for this, but it surely’s worth checking for spyware and adware)
There’s some good free software out there from Lavasoft referred to as AdAware. Microsoft also have their very own free device for Home windows users referred to as Windows Defender. Among the paid-for Anti-Spyware software program Webroot’s
Spy Sweeper commonly picks up awards from pc magazines.
PASSWORDS
Increasingly more individuals are accessing safe websites for procuring, banking, etc. Supplied you’re taking wise precautions it’s a good way to shop.
For those who’ve been doing any online shopping you’ll be used to dealing with secure sites. No matter methods these sites use to safe their servers or encrypt your traffic, if they’re accessed by passwords then you share a number of the responsibility for the safety in your transactions. Listed here are a couple of recommendations on find out how to keep unauthorised users from accessing your accounts:
– Be inventive with your passwords. Don’t use easy to guess stuff that lots of people know about you or can find out. Use a combination of uppercase and lowercase characters, numbers and particular characters (once more be inventive. Just using a 1 as a substitute of the letter i isn’t any use if it still spells out an easy to guess phrase).
– Use totally different passwords for different accounts. Should you always use the same one and it’s compromised then someone may have access to everything.
– Don’t write passwords down on paper or post-it notes. That is a hacker’s favorite technique to discover passwords if they’ve physical entry to your office.
– Do not get Net browsers to remember your passwords on shared machines or in workplace areas. If you happen to log right into a machine that other users have access to then never use Windows or Web browser mechanisms that bear in mind your account details.
Having totally different passwords to lots of different accounts does make it tougher to remember them and it is important that this does not lead you into unhealthy habits. So what do you do?
You would take a look at getting some password management software. Naturally, Norton has a password manager, however other good options embrace “Net Replay” from Deskperience or “PC Password Supervisor XP” from CPLab.
WHERE TO NOW?
You don’t have to go out and purchase every piece of safety software proper away. Prioritise one or two to start with (I would recommend Antivirus and Firewall software program). Also download trial versions so you could be certain you are happy with them earlier than you part along with your hard-earned cash.
Watch out on the Internet, but do not let it spoil your day.
