Get Rid of Win Defrag Antivirus? How to Uninstall Win Defrag Fake Antivirus? How to remove Win Defrag Antivirus manually?

What is Win Defrag?

The fake defragmenter family now has another fake antivirus known as Win Defrag Antivirus which is not a real antispyware but itself a spyware, more precisely a new kind of fake antivirus program from the same family of HDD Defragmenter, Ultra Defragger, Scan Disk & Check Disk . This program is distributed with the aid of Trojans from various web sites. When Win Defrag Antivirus is started, it will simulate a fake system scan and detect a lot of various infections which actually does not exists in your computer & scars you that will not be fixed unless you first buy the program. Be aware all of these reported infections are fake alerts and disregard the scan results.

While Win Defrag Antivirus is running, it will create lots of inconvenience such as bogus alerts, annoying pop ups, fake scans and block the ability to run any programs as a method to frighten you into thinking that your computer is at risk and affected with spyware.

The below fake warnings will be shown.  Ignore all these fake alerts and follow the below instructions to remove these fake antivirus messages.

Windows detected a hard drive problem.
A hard drive error occurred while starting the application.
OR
Windows cannot find notepad. Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search.

Critical Error!
Damaged hard drive clusters detected. Private data is at risk.

Critical Error
Hard Drive not found. Missing hard drive.

Critical Error
RAM memory usage is critically high. RAM memory failure.

Critical Error
A critical error has occurred while indexing data stored on hard drive. System restart required.

System Restore
The system has been restored after a critical error. Data integrity and hard drive integrity verification required.

How to remove Win Defrag Antivirus manually
Remove the following files and registry entries. If you do not have enough expertise in dealing with computer files, folders, processes, DLL files, services & registry entries, please take aid from some one who can does this for you because manual deletion is a tedious process and does not always ensure that the deletion of the spyware antivirus is complete

Or simply Get Reimage key by going to PC Reimage in order to get rid of Win Defrag Antivirus.

In Order to get rid of Win Defrag, you need a solid tool to repair the damages caused by the rogue antivirus. It alters files, folders, permissions and registry keys altogether that may still live and make your PC sluggish and to stop from getting re-infected.

In order to get rid of Win Defrag Antivirus completely, start your PC in safe mode with networking. You should repair the proxy settings of Internet Explorer.

Run Internet Explorer, Click Tools -> Internet Options, Select Connections Tab and Click LAN Settings button.
Uncheck "Use a proxy server" box. Click OK. Click Apply. Click OK. And go to http://pcreimage.cz.cc/ to run a Scan.

Reimage works by comparing each and every OS system files with the correct files from a World Wide Web repository of 25 million OS components to recover the damage. This is the sole reason you can get a PC as good as new once you run Reimage, all other antivirus and antimalware programs only delete the virus….but they don't fix the damage…which results in re-infection and slow performing PC.

Reimage first scans your computer exhaustively; all the files, folders, registry keys and values, drivers, software, stacks and then either repair or remove those stuffs that should be there. They have an enormous web repository of application, drivers, system objects, etc. from where they compare your PC's files and if corrupted replace it with the healthy ones.

Is it possible to detemine the energy remaining in the exhaust of this Steam Engine

This is a 1 Liter 2 cylinder simple steam engine that has 100 PSI of steam pressure and is operating at 1200 RPM. What is the Torque and how much energy remains in the exhaust if the exhaust temp is 100 deg C.

My first reaction was, "no way", but on reflection, with a number of assumptions, the answer seems to be yes.

Let's start from top dead center of an over-simplified engine:

1. The intake valve is opened and steam at 100 PSI and temperature Ts comes in. This exerts force on the piston proportional to the area of the piston A.

2. As long as the intake valve stays open, more steam enters the cylinder, so both the pressure and the temperature stay constant.

3. At some point the intake valve closes and the steam in the cylinder expands and cools. This is the period of adiabatic expansion, which continues until bottom dead center. At the end of this period, the steam is at a temperature of 100 deg C and pressure Pe.

4. The exhaust valve opens, and as the piston returns to top dead center, it pushes the steam out of the cylinder.

Now come the assumptions:

A. Since the exhaust is at 100 deg C and this is a simple engine, then we can assume that Pe, the exhaust pressure, is one atmosphere - about 15 PSI.

B. If that's so, then the exhaust steam is almost certainly saturated. Let's assume that the steam is saturated throughout the cycle (i.e. the intake steam is not superheated).

These assumptions provide the additional constraints we need.

1. For saturated steam there is a relationship between pressure, volume, and temperature that allows us to determine the path in the state diagram for the adiabatic expansion phase.

2. This allows us to determine the percentage volume increase during the adiabatic phase. Since we know the total volume of the cylinder, this also tells us where in the power stroke the intake valve was closed.

3. This means that we can compute the mean pressure in the cylinder during the power stroke.

4. Work = Force x Distance = Pressure x Area x Distance so Work = Pressure x Volume. We don't actually need to know the linear dimensions of the cylinder, just the volume, which we are given.

5. Together with the RPM, we can compute the total power output of the engine and the torque as well.

6. Finally, we know just how much saturated steam we have in the exhaust and so how much energy there is in it.

As Mark Twain noted ("Life on the Mississippi" chapter 17):

"There is something fascinating about science. One gets such wholesale returns of conjecture out of such a trifling investment of fact."

Of course, none of the numbers you get will bear any relationship to the values for a real steam engine, no matter how simple.
