How To Defend Yourself Against Adware

You might have come across a number of advertisements while browsing on web. Have you ever wondered why such advertisements pop up from nowhere and sometimes even crash the programs that might be running on your system.

Adware is nothing but an advertizing based software. The advertisements that are displayed on your screens may seem legit and harmless but can install adware into your computers. When once it is installed, it can track your personal information such as age, location, buying habits etc. Also it can gain access to your browser history which means your personal and confidential information is no more private. The main reason behind the whole mechanism is to fool you and make you install illegitimate programs that display hoax advertisements.

How Do You Know If Adware Is Installed In Your Computer?
You can identify if your computer has an adware in it or not. Here are some signs that you must lookout for –

  • You are subjected to a numerous number of pop- ups and advertisements.
  • The performance and speed of your computer becomes slow for absolutely no reasons.
  • An unfamiliar search bar appears in the web browser.
  • There is continuous change in the browser homepage.
  • You search for some website but you are redirected to another website.
  • Programs start crashing.

How To Defend Yourself –

  • Don’t download free programs as they can increase the chances of injecting adware to your system.
  • Install pop-up blockers to keep unnecessary advertisements at bay.
  • Be wary of files and links from untrusted sources. Make sure that you do not download or click them.
  • If you are suspicious of the content of a particular website then it is best to avoid it for security reasons, lest you will lose your important information and credentials.
  • Usually permission to install such adware’s is deeply embedded in the licensing agreement. So ensure that you read it thoroughly before granting any permission to install or download a particular program or file.
  • Do not click on forwarded emails and messages unless you are sure about the source from which it is sent.
  • Update your system regularly.
  • Install an appropriate anti-virus software.
  • Remove the cookies every now and then.
  • Install a firewall to stay away from such adware.
  • Do not click ‘OK’ or ‘YES’ without reading what a particular pop up says, as this sudden haste can lead to a multitude of problems.
  • Adjust your browser settings such that your internet zone setting is on medium security or above.
  • Do not install an unwanted program or software even if it is free.
  • Run an anti-adware software on regular basis to prevent any major issue.
  • If you witness a suspicious activity which can result in installation of adware or some malware onto your system, then it is best to turn off your computer using the power button.

It is extremely important to be aware about adware and the effect it can have. For more information on IT Security, call Centex Technologies at (254) 213-4740.

Things To Check If Your Internet Is Blocked On Your PC

December 30, 2014

You might have witnessed times when you are suddenly unable to connect to the internet from your computer system. This could be due to several reasons which most people are unable to detect. Given here is a complete list of the common things to check when you witness internet connection not working on your PC.

Unplugged Network Cable Or WI-Fi Disabled

This is the most common reason why most people are unable to connect to the internet. The connection failure is not due to a problem in the network, but because of Wi-Fi adapter been shut off in the laptop. In home networks, the router might have been inadvertently unplugged by someone.

Rule Out Fake Alarms

Instead of problem in your network connection, there are chances that a particular website may be down. Hence, before assuming any conclusion, make sure you visit several popular websites rather than just a single one.

Avoid IP Address Clashes

If more than one computer is using the same IP address, the clash between them can also prevent the internet connection from working properly. To resolve this issue, you should renew the IP address of any of the computers having confilct. If your network has a static IP address, you can manually change it to any other number.

Check For Faults in Computer Firewall

Firewalls installed on many computers are intended to restrict unauthorized traffic to affect network processes.  Regrettably, due to an error, these software systems can sometimes also block valid internet users. Also, when more than one firewall is installed on the same computer, conflicts between them can also lead to erroneously block traffic. If you have recently updated or installed a computer firewall system, disable it temporarily to see if it has been causing the problem in internet connection.

Check If Wireless Signal Is In Range

If you are on a Wi-Fi network, the performance of the connection will be influenced by the distance between the wireless access point and computer system. Farther the Wi-Fi device, slower will be the internet speed. Determine the strength of your wireless connection to diagnose the problems in your internet.

Changes In Wireless Network Configuration

Wi-Fi networks usually require matching WEP or WPA security keys to connect. If a person changes the password or encryption key at the access point, all the devices will be unable to connect to internet. You can contact the network administrator to confirm if the pin has been changed recently.

If all the above things are working correctly, contact your internet service provider to check if there is an outage in your area. They can also guide you to troubleshoot the connection problem.

Bandwidth Management For Fast Loading Websites

May 19, 2014

With so many websites on the internet today for every topic under the sun, users always look out for getting the maximum information in the least amount of time. To be regarded as a user-friendly website, the single most important criterion is the time it takes to download the webpage. The quicker it loads, the better it is. Even if you have the best of website designs and layouts, if it takes too much time to load, the user will want to skip browsing through it.

Following are some tips that will help you to better manage the bandwidth of your web servers so that the time taken for loading a particular website can be reduced.

  • Firstly, it is important to understand the meaning of bandwidth in context of web servers. Bandwidth refers to the bytes of data that are transferred from the web server that contains the files of user interest, to the user’s browser. The larger the file size, greater will be the bandwidth consumed.
  • The next step is to analyze the monthly bandwidth that you will require on your web server or web host so that your website can be easily loaded on a user’s browser. The bandwidth needs vary from website to website depending upon the type of content that is used and number of visitor visiting the website. For example, if your website makes use of multimedia-rich content such as videos and sound clips, the amount of bandwidth required would be more than a website that simply uses plain text content.
  •  Also, it could be the case that you envisage expansion for your website in the future, with more number of users expected to visit your website. So you will need to focus on having more bandwidth so that the website loads fast and does not become inaccessible in the event of many users accessing it.

Proper management of bandwidth will not only make your website download faster, but also help you to keep the costs for web hosting under control.
