IaaS - Cloud Computing

What is Infrastructure as a Service (IaaS)?

Infrastructure as a Service (IaaS) is a way to rent storage, hardware, servers and network capacity over the Internet. The service provider owns massive computer resources and is responsible for running and maintaining them. Meanwhile, the client needs only computer and Internet connection to access these bottomless resources and typically pays for it on a per-use basis.

The main features and components of Iaas are:
  • service-oriented utility computing,
  • automation of Auto Infoistrative tasks,
  • unlimited resources,
  • on demand self-service,
  • pay-per-use pricing,
  • desktop virtualization,
  • policy-based services.
Infrastructure-as-a-Service (IaaS) is one of three models of cloud computing service. The other two are Software as a Service (SaaS) and Platform as a Service (PaaS).

PaaS - Cloud Computing

What is Platform as a Service (PaaS)?

Platform as a Service (PaaS) gives a possibility to run, create or test various applications by using provider's tools over the internet. The consumer has no rights to manage or control the underlying cloud infrastructure (storage, servers, platforms, etc.), but is able to configure application hosting environment and the installed applications.

Advantages of using PaaS are:
  • possibility to change and upgrade the characteristics and components of operating system,
  • easier collaboration with specialist over the word,
  • opportunity to use resources that are over the national border without crossing it,
  • overall cost reduction by minimizing the expenses of hardware and programming tools, incompatibility problems and so on.
Disadvantages of using PaaS are:
  • some providers may not allow moving developed software out of his platform (security issues),
  • flexibility of this service may still be insufficient in meeting the needs of users, whose requirements are constantly changing.
Platform as a Service (PaaS) is one of three models of cloud computing service. The other two are Software as a Service (SaaS) and Infrastructure-as-a-Service (IaaS).

SaaS - Cloud Computing

What is Software as a Service (SaaS)?

Software as a Service (SaaS) is a cloud computing model, which hosts various software applications and makes them available to customers over the Internet or other network. There are two main software delivery models for SaaS:
  1. to give an online access to a single copy of an application,
  2. to host commercially available software and deliver it over Internet.
The last opportunity is very similar to one, which is used for other on demand computing software delivery models, for example ASP (application service provider). However due to its global accessibility and main technologies that support service-oriented architecture (SOA), Web services and even new developmental approaches, SaaS is becoming more and more popular amongst other software delivery models.

The main advantages of SaaS model are:
  • no concerns about software buying (licenses), installing and maintaining,
  • automatic updates and patch management,
  • automation of Auto Infoistrative tasks,
  • easier collaboration with other users – everyone has the same version of software,
  • world-wide access.
Software as a Service (SaaS) is one of three models of cloud computing service. The other two are Platform as a Service (PaaS) and Infrastructure-as-a-Service (IaaS).

Remove Windows XP Fix, Windows Vista Fix or Windows 7 Fix (Uninstall Guide)

Windows XP Fix, Windows Vista Fix or Windows 7 Fix (depending on the version of Windows that your computer is running) is a fraudulent system optimization program that displays quite legitimate looking but unfortunately fake pop-up window warnings designed to scare you into thinking your computer has some really serious hardware and software issues. It generates dozens of erroneous infections or Windows stability issues and blocks legitimate applications to trick you into participating in fraudulent transactions.



Windows XP Fix, Windows Vista Fix claims that you should pay for a license to the rogue program in order to fix system errors, clean your registry and protect your computer against new threats with software updates. It's probably one of the most annoying and troublesome scareware that we've seen so far. Windows XP Fix moves software shortcuts found in various directories to Windows temporary folder, specifically %Temp%\smtmp, %Temp% refers to Windows temporary folder. What is more, the rogue application adds +h or otherwise known as hidden attribute to some of your files on folders. It's obvious that Windows Vista Fix or Windows 7 Fix wants to make you think that your files were deleted because of critical hard drive and system errors but at the same time it states that they could be restored if you pay for a full version of the rogue software. To remove Windows XP Fix, Windows Vista Fix or Windows 7 Fix from your computer and restore your files, please follow the steps in the removal guide below.

Here are some examples of a warning pop-up windows from this rogue program:







First of all, do not delete anything from Windows temporary folder; otherwise you won't be able to restore your software shortcuts and some other files. I'm saying this because I know that some of you guys use CCleaner or similar software to remove files from %Temp% folder that could be associated with malicious software. Although, that's a good idea when it comes to computer viruses, but Windows XP Fix is an entirely different side of the story. But that's not all, Windows XP Fix, Windows Vista Fix, Windows 7 Fix or in some cases malware droppers install the TDSS rookit as well. It could be either TDL3 or TDL4 version of this rootkit which is probably the most sophisticated piece of malicious software that I've ever seen. I think it should be already obvious that it's very hard or even impossible to remove this rogue application and associated malware manually. You will have to use anti-malware software and TDSS rootkit removal tools, either TDSSKiller from Kasperky lab Norton TDSS removal tool. For more information, please follow the removal steps below.

Additionally, you can activate the rogue program by entering this registration code 8475082234984902023718742058948 and any email as shown in the image below.



Once this is done, you are free to install anti-malware software and remove the rogue anti-virus program from your computer properly. If you have any further questions, please leave a comment below. Good luck and be safe online!
