Fake Tech Support Scams

Today I received a call from a friend informing me that they had malware loaded on their computer and that every time they were using their browser regardless of which browser they were using they were getting this nag screen claiming that Microsoft was informing them that their computer was infected by malware and to contact Microsoft to have the problem resolved.

The quick solution is to use a malware detector and remover, there are a few free ones available online.

If that doesn’t clean your computer then you may have to take your computer to a technician to remove the malware from your computer depending on the complexity of the malware that it may be an expensive venture with no guarantees that all has been removed.

Manually removing viruses, rootkits, malware and trojans can be very time consuming, I have known people to run bills over three hundred dollars.

So the cheaper solution is reinstalling the operating system, and reinstalling all your software (pain in the ass).

It is always good practice to backup you datafiles for two reasons, the first in the event that you have to reinstall your operating system the second hard drive failure.

Below is a link that will show you what this Microsoft popup window looks like.

(A dead giveaway is that if you are using a Linux os or mac os and you get a Microsoft message ) then you are being scammed … lol

The other version of this fake tech support scam is the telephone call, with this scam you are called on the telephone telling you that your computer is infected and that they can fix your problem. (Yeah Right!),

For the Microsoft Tech Support scam here are two images that you might recognise if you have encountered the experience.

Windows 10 System Commands

By André Faust

System commands are commands that can be run from the command prompt or in linux terminology Terminal. the Commands to be similar to DOS. DOS before the days of Windows was standalone operating which was initialized with command.com.

The early programs under DOS the visual interface was dependent on A.S.C.I.I. ( American Standard Code for Information Interchange) characters for the visual appearance. in figure 1 show is a screen shot of word Perfect 5.1. As can be seen the graphics are low quality compared to what we have today.

In 1993 Microsoft deployed Windows 3.1 Fig 2. it was one of the GUI (Graphic User Interface),e however it was almost Identical to the Mac Classic. Apple launched a lawsuit against Microsoft which dragged on for years..

DOS (Disk Operating System) was still then OS (Operating System) with Windows 3.1 running on top of it. 1995 was the release date for Windows 95, in 98 Windows 98 introduced into the market, in 99 Windows 98 SE deployed to the consumer market.

All three versions of Windows 9x sere still running on top of DOS the change came with windows millennium in 2000 where Microsoft change the architecture of the Operating system to incorporate DOS in the architecture. the result is that DOS and the windows operating system are the same.

While on the surface the commands may look like DOS, it isn’t. No longer the operating system separate form the windows kernel

New web site to be launched in the next couple of days

WebpageHome

I am in the final stages of developing the new site to replace the old site that was created back in 2008. The new site is built on a responsive architecture, meaning that it will display on both large screen and small screens found on mobiles. The site will work in conjunction with this blog, twitter and the FaceBook page by the same name Andre the Tech Guy.
