What is the Google Redirect Virus and What a Hosts file?

Redirect virus redirects the browser to another site, instead of where you wanted.

Many times this is for you to send to a website with advertising to get you to buy something. Other times it can be used to send to a fake online banking site to try to get your account information.

Redirection malware or viruses usually change a file on your computer called the "hosts" file

Before discussing what the hosts file. Isomething to explain how a website with your web browser.

There are some popular web browsers today a number of Internet Explorer, also known as IU Firefox, Google Chrome and Safari. There are more available, but this seems to be the ones I see people who use more.

Before a site has a numeric address like a phone number or address.

So, for example, Google has an address of 208.69.32.231 (the IPaddress) you can type in the address bar of your browser and it would take to Google. The problem is that trying to remember the numbers is much more difficult for humans to use the name.

If you have a website at the request of the computer name first time you watch the hosts file to see if it is listed there, usually there are no entries in the hosts file. If an entry for google.com with an IP address of your computer you can send to that IP address, even if it is not aaddress associated with Google.

If no entry of Google or the website that you want to go to the computer), contact a DNS server (Domain Name to see the numeric address of the site.

It shows that Google = 208.69.32.231, and the computer, the Web site you were looking for which is located at the address.

The virus creates an entry for forwarding to the Google site or a website and add a fake IP address or IP addressbelongs to another website. If you want to go to that site your computer will go to the false / incorrect IP address in the hosts file.

So here it must first scan the computer and determine the hosts file to resolve.

The hosts file can also be used to help protect against bad Web sites. If you have a list of bad websites in the world, you can see in the hosts file and use the IP address 127.0.0.1

The voice soundedthis

badwebsitename 127.0.0.1

Then you or someone using your computer tried to go bad in one of the sites in the host computer file, then the browser an error page that basically says that the page can not be displayed.

So you might ask what is 127.0.0.1 or 127.0.0.1 where there is a simple answer, it is your computer.

It's called loop back address.

Then, because there is no website running on your computer, loop-back address that you get the page can not be displayed error, which is much better than going to a website that viruses or malware on it.

There are sites that maintain a host file with a list of known bad sites. If you replace the hosts file with it, you can protect your system from malware.

There are other types of viruses that can cause a diversion, some may even change the setting to the router and DNS server will send an evil.

Then the "poisoned"> Server DNS forward. So you can guess the problem lies in the computer, but it is also possible that the router has been hit by a virus.

Website Performance and Page Speeds Are Now Relevant to Google Page Rank

No more slow web pages - no more excuses!!

We all hate web pages that are slow to load but many site owners now believe that we all have high speed broadband connections and that they do not have to design a site for performance. How wrong they are! The network performance speeds can massively vary as most broadband connections are heavy contended. This means the end user experience of a site can still vary from very fast to frustratingly slow.

In addition to this, the average home connection does not have a high tech QOS to ensure that you can do your online banking when little Tommy next door is hammering the line downloading the latest game!

This new consideration launched by Google signals the beginning of interesting times. Network Managers are now going to have to align their work efforts even closer to the site business owners' to achieve the mutual goal of speeding up their website.

Maybe discussions about site design and the overhead of delivering large pages with many objects will be jointly had between IT and the Business? SEO, Sales, Marketing, Development and Infrastructure will all have to work and "compromise" together to achieve performance related objectives.

We are not very forgiving of slow web sites and will typically blame the site that we are visiting for an unsatisfactory experience. Whatever the reason and wherever the fault lies, the end user will leave with a negative perception of the site based on their encounter. It is not your fault but it is your problem!

Ecommerce sites are typically ahead of the curve on site performance as they know that faster sites offer a better user experience and in turn will increase the 'Browse to Buy' ratio thus making more money! With the new Google SEO implications, site performance will become increasingly important. Interestingly enough the ROI time of budget spent on optimising site performance will be further reduced.

So what can we do?

Websites are normally slow due to one of more of the reasons below:

1. The DNS server takes some time to resolve your domain name to your IP.
2. The Application/ web server is slow to create the web pages (maybe dependencies on backend systems such as databases etc).
3. The pages are large and take some time be sent to the client.
4. The code is not efficient for the browser to render.
5. Any part of the connection between the server and client connection is slow.

Remember the network is only as fast as the slowest link! So it does not matter if you have a high speed server network if you users are accessing your site over a contented ADSL. This is the last mile problem!
