A lot of the recent posts i have been putting up have been focused on our “computer hardware and software fixes” category but this is because recently a lot people are calling me up to fix their computers due to serious virus attacks, some of these can only be fixed by re-installing the operating systems but for now lets focus on the virus issue i encountered recently.

PROBLEM:

A client’s laptop had been seriously infected by an ativirus software that invaded its memory and messed up everything on his computer including his screen colour was changed to dark so the desktop is completely invisible. The good luck was the fact that this computer can still boot normally and connect to the internet but you cannot download as there are no memory to run programs etc. All the antivirus on the computer was expired and new ones cannot be downloaded from the internet because of memory issues

SOLUTION:

The good thing about this virus is the fact that it shows itself as an antivirus program asking you to upgrade, i simply did the following;

I clicked on the “start” button, then clicked on “All programs” and when the list of programs appeared, i checked to see if i can identify the virus in the list of programs, luckily it was there having known the program to look for. I right clicked on the program and then clicked on properties to see the whole information regarding this program. On the properties tab, i was able to see the folder and file causing these problems, since i was using Windows Vista, i copied the whole folder and file path and pasted it on the search form immediately you click on “start” icon , this helped locate the folder and file after some little search , i tried to delete the file but it refused.

After some attempt trying to delete the file with no success, i finally took the option of renaming the file. This is intended to disorganise the file path so it cannot find the file anymore to execute with that name and luckily this worked. Just to make sure i have changed the name, i tried to search for the old file path and couldnt locate it anymore.

After this the system was rebooted  there we go, everything went well, the page loads normally, the internet and web pages became easily accessible etc.

I changed the desktop appearnce from dark to bright colour and there we go. I was then able to purchase the latest version of antivirus and cleaned up thoroughly.

Hope this helps out.

Though downloading avira is faster,rising antivirus is equally a high perfomance software. Please read the from the site below.

I was in a forum searching for an answer on how to find and edit a particular part of a CSS file  and i stumbled on the firebug . Simply put, this firefox addon is one of the best experiences for any web developer, all you need to do is simply download it from the site, then after it as been installed you would see the great difference it will make in your developing experience.

To access  firebug after it has been installed, please go to tools and then click on firebug to open up.

Practically just open up any webpage you would like to take a look at the codes, then go to tools and open up firebug, you would immediately see the a new window with options of viewing html,  css and DOM. If you are good with your browsing, it wouldnt be that hard to get around. It will even indicate what part of the site any code you see on the firebug is associated with. Please read an extract from firebug below.

“Firebug integrates with Firefox to put a wealth of development tools at your fingertips while you browse. You can edit, debug, and monitor CSS, HTML, and JavaScript live in any web page…”

Hope this helps.

Hello All,

I know this might sound like one stupid thing everybody knows but i can bet you that you would be surprised to discover the amount of people using wireless connections on their laptop that do not understand this.

I remember putting on  my laptop one day and with the happy smile of diving into the internet world but i was surprised to find that i couldnt get online, i tried everything i could, went into the wireless network display window and found that i could not search out any available wireless network around me which is very unusual. The window was completely blank.

Honestly, i thought my ISP or modem was having problems but just i was about to call the company after some hardtimes on trying to find the problem, i took one close look again around the laptop and discovered a switch with a wireless symbol around it and it was switched off. I switched it on and there i was back on the internet.  I felt really ashamed of myself that i didnt think of it before.

About a month after, my cousines wife was crazy about her laptop messing her up and after talking to her on the phone, i knew the culprit immediately. I directed her on what to do and that’s it. She was back online again.

How did this happen in the first place? , Well its just a little human error of mistakenly switching it off without knowing.

Hope this helps.

Often you would find that you are not able to connect to the internet but there is nothing wrong with the system on your ISP’s side(INTERNET SERVICE PROVIDER).

Before you start becoming agitated, try using the “PING” (PACKET INTERNET GROPER) method to see if you have a connection established with the internet. Now this is done remotely using the secure shell access or Telnet. Most people are usually not too familiar with these because you only use it when you want to troubleshoot a problem remotely or make use of some functions remotely.

There are so many commands that can be used remotely but for this particular lesson let us concentrate on the PING command.

This is how to use the PING command in windows:

If you are using windows XP then follow these procedures but if you are using Vista then the procedure is the same but with slight differences on where you will find the navigation links to run remote process.

Using XP on your desktop select Start then Run and then type CMD in the command prompt box. A command window with dark background will appear.

In the command window type ping www.anysite.com and press enter You should recieve some response text starting with ;

Reply From IP blah blah blah.

This will appear in up to 4 lines of the text. If you get that response then that means you have a connection to the internet . If you are still experencing a problem not connecting to the internet, i would suggest you shut don your modem/Router, leave it for some 10 mins and the start it up again. Sometimes a slight change from the ISP might  have reset your router configuration and it will need to be started again in other to pick up the new configuration.
