How To Remove haha.js

Its a javascript and not that really harmful to your PC but a little bit annoying though. Most noticeable effect if your PC are infected with this worm is the tittle bar of your IE change to "haha" word.

Some of the antivirus does detect this worm. Here is the way how to remove it manually..

Step 1
On your mycomputer menu option go to Tools>Folder option
uncheck box "hide protected operating system files"in Tool-Folder options and check "show hidden files".

Step 2
Open Task Manager by pressing ctrl+alt+del. End Process all Wscript.exe that you can found in the Task Manager(some times it can be more than one process)

Step 3
Open mycomputer and search for haha.js files and delete it there should be an autorun.inf file comes with this haha.js just delete it

*this haha.js run when you use double click to open your drive c: ,d: ,e: ..when removing this worm use right click instead to open any drives. Don't forget to look and delete this haha.js in your external hd and thumbdrive

Step 4
Go to Run type msconfig. At the startup tab look for any haha.js @ wscript.exe unchecked and delete the key location in the registry.

finally restart your PC. Good luck on trying!

Should you turn off your PC

Should you turn off the computer or the monitor when it is not in use?

Alternatively, should it be left in Standby mode?

When you turn on electrical equipment it uses a large amount of power, and then it goes down to its “rated consumption” as stated on the label. This is measured in watts or kilowatts. This sudden jump in electricity is know as a spike. You can see it on a digital power meter, but there is a way that it can be observed more easily.

Just switch on your air conditioner, refrigerator, or vacuum cleaner. It’s best if that appliance is plugged into the same circuit for the purpose of this experiment.

Your lights may dim briefly and then resume their former brightness during this “spiking” and it will then go back to its normal level of power.

Another way of looking at this is with a standard incandescent light bulbs. Have you noticed that they seem to be able to stay on forever, but they burn out when you turn them on? That’s also because of that initial spike of electricity.

So, what’s the problem?

Computers have delicate electronics inside of them. The electronics in laptops may be even more delicate. As the computer ages, the components suffer from repeatedly being turned on and off (technicians say that the parts are fried). Over the course of time, the repeated spiking damages some components. It is thus a good idea to reduce the number of times that you spike these delicate parts.

So, computers should be left on, right?

Well, laptops heat up more than desktop computers, so it is not a good idea to leave them on. Laptops do not have the same system of fans that is in desktop computers. Leaving it on will fry the parts in a different way than turning it off and on, but the result will be effectively the same.

OK, so I’ll leave the computer in Standby or Hibernate mode

Those modes are different, as follows:

Standby

The machine is powered down so that it uses practically no power.
Your data is saved (if you have enough installed memory)

Hibernate

The machine is powered off.
The data is saved as an “image” on the hard drive. When you turn on the computer, everything is where it was. Unsaved unsaved work is restored, Windows is in its familiar position, and you can continue working.

Lower your electric bill

Hibernation and standby options are available because laptops have limited battery life and desktop computers use a considerable amount of electricity.

The “Energy Star” power consumption rating shows that manufacturers are becoming aware of the environment.

Standby mode is useful when a laptop is moved from one location to another. Batteries last significantly longer between recharges.

Hibernate, on the other hand, is not as useful. It takes nearly as long to power up to your previous state, and you still spike the mainboard during this time. You may want to use it because your Desktop seems to appear the same as the last time it was used.

Standby mode therefore seems to be a better option for extending the life of laptop. This is important, because laptops cost more and they are replaced less frequently. This issue is less important with a desktop computer.

There is still another option: You can have many of the benefits of switching the computer off and having the benefits of Standby mode.

Use the power setting in the Control Panel

Many computer programs “leak” memory. If a computer program uses 15MB when it is started, it may use 55MB two weeks later. This has nothing to do with anything you’ve done, and it is not because the program is working any harder. The programs leak memory because they are written and designed poorly.

What is the solution?

Restart your computer periodically. Better yet - leave it off overnight from time to time so that the parts can cool down to room temperature. I turn off my own computer once a week for Shabbat. I find that to be a reasonable compromise.

During the week, between these rest breaks, use the standby function in order to prolong the lifetime of your investment.

Disk Cleanup Freeze?

It's a very common problem that many newbies almost always ignore to correct; that when you try to the Disk Cleanup tool, it may stop responding and you may receive the following message:

Disk Cleanup is calculating how much space you will be able to free on (C:). This may take a few minutes to complete. Scanning: Compress old files

This problem happens when there is an incorrect entry in the registry that is used by the Disk Cleanup utility to locate compressed files. In my view, I've noticed it happening to clean formatted computers as well, so I would suppose that the problem in the registry too is probably a faulty of M$ programming.

But here is a good little trick to follow if this happens to you:

1. Create a registry file by "right clicking" on the desktop > New > Text Document.
2. Name it anything you want with .reg extension. For example: diskcleanup.reg
3. Right click this file > Edit.
4. Type in the following code, then save and close:

Windows Registry Editor Version 5.00 [-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\VolumeCaches\Compress old files]

That's it! It should have done it. Try running the Disk Cleanup now and see if it is any faster than before.

This tutorial has been test to work on WinXP Pro and Home only. That doesn't mean it won't work in other WinOS. Just that it's not been tested in others.

Disable Error Reporting

Whenever either Windows crashes, you will be asked if you want to send an error report to Microsoft. It's annoying, so here's a way to disable it:

1. Open the Control Panel.
2. Click on System.
3. Click on the Advanced tab.
4. Click on ERROR REPORTING at the bottom.
5. Select DISABLE ERROR REPORTING.
6. Click OK.

It's as easy as that.
