When there is less physical memory than needed, then some virtual memory (Virtual RAM) is created on the disk. When there is a limit set to the size of Virtual Memory usage and there is not enough of it present there is a warning that frequently comes “Virtual Memory too low”.

Solution 1 :-
This problem occurs when physical RAM + Virtual RAM (usually created on hard disk) together are not sufficient to take care of the currently needed RAM size, or this situation is about to arise. This usually happens when some fixed upper limit for Virtual Memory has been set. To solve this problem, you can either upgrade you physical RAM on your computer (recommended), or you can set the Virtual Memory to system managed size or you can do both. Setting Virtual Memory to system managed size means windows will set it to higher size whenever needed automatically, for this,

Right click on My Computer –> goto Properties, goto Advanced tab, click on Performance Settings, now click on Advanced, now click on Change button for Virtual memory.

On this screen select the System Managed Size, press OK. After this re-start your computer. This will solve the virtual memory too low problem.

Solution 2 :-
Recommended solution is to upgrade your physical memory (RAM) according to requirements of the kind of applications that you run on your computer. If you upgrade RAM or not, the following procedure will help prevent this warning by increasing the virtual memory limit.

Right click on My Computer icon and click Properties.

This will show system properties window. Click on a Advanced tab and click on the Settings button under heading Performance.

This will open Performance options window. Click on Advanced tab and click on Change button under heading Virtual Memory.

Check if the space available is set to some custom value or double the RAM size ? If it is not double the RAM memory size , then select the size option set the virtual memory size double the RAM Size and press set button and press OK button.

Restart the computer.

THANK YOU……

a dos window will appear with following like that…..

DISKPART>

Step-2.
Then type “ list volume ” without quote

It will look like this…..

Step-3.
If u want to hide drive F then type “ select volume 5 ″ without quote

then a message will appear in same winwods { Volume 5 is the selected volume }

Step-4.
now type ” remove letter F ” without quote

now a message will come { DiskPart successfully removed the drive letter or mount point }.

sometime it requires the reboot the computer .

Diskpart will remove the letter. Windows XP is not having capabilty to identify the unkown volume.

How to come back / recover:

Don’t afraid, all of your Data still safe .

to Come back the Drive repeat the process . but in Step-4, which is shown in this post replace “ remove ” to “ assign ”

means type “ assign letter F ” without quote

The above method won’t work for the drive containing Operating System.
and it can also be done using System Manager>Storage Manager.

1) first of all copy the following code in notepad
Code:

cls
@ECHO OFF
title Folder Locker
if EXIST “Control Panel.{21EC2020-3AEA-1069-

ControlPanel.{21EC2020-3AE

I was surprised that my most reliable friend Avast, for the first time failed me in this war against viruses but then again avg and bitdiffender also failed against it. This virus is know popularly as regsvr.exe virus, or as new folder.exe virus and most people identify this one by seeing autorun.inf file on their pen drives, But trend micro identified it as WORM_DELF.FKZ. It is spreading mostly using pen drives as the medium.

Well, so here is the story of how i was able to kill the monster and reclaim my hard disk space.

Manual Process of removal

I prefer manual process simply because it gives me option to learn new things in the process.

So let’s start the process off reclaiming the turf that virus took over from us.

1. Cut The Supply Line

a. Search for autorun.inf file. It is a read only file so you will have to change it to normal by right clicking the file , selecting the properties and un-check the read only option
b. Open the file in notepad and delete everything and save the file.
c. Now change the file status back to read only mode so that the virus could not get access again.
d.
e. Click start->run and type msconfig and click ok
f. Go to startup tab look for regsvr and uncheck the option click OK.
g. Click on Exit without Restart, cause there are still few things we need to do before we can restart the PC.
h. Now go to control panel -> scheduled tasks, and delete the At1 task listed their.

2. Open The Gates Of Castle
a. Click on start -> run and type gpedit.msc and click Ok.
b.
c. If you are Windows XP Home Edition user you might not have gpedit.msc in that case download and install it from Windows XP Home Edition: gpedit.msc and then follow these steps.

d. Go to users configuration->Administrative templates->system
e. Find “prevent access to registry editing tools” and change the option to disable.
f.
g. Once you do this you have registry access back.
3. Launch The Attack At Heart Of Castle
a. Click on start->run and type regedit and click ok
b. Go to edit->find and start the search for regsvr.exe,
c.
d. Delete all the occurrence of regsvr.exe; remember to take a backup before deleting. KEEP IN MIND regsvr32.exe is not to be deleted. Delete regsvr.exe occurrences only.
e. At one ore two places you will find it after explorer.exe in theses cases only delete the regsvr.exe part and not the whole part. E.g. Shell = “Explorer.exe regsvr.exe” the just delete the regsvr.exe and leave the explorer.exe

4. Seek And Destroy the enemy soldiers, no one should be left behind
a. Click on start->search->for files and folders.
b. Their click all files and folders
c. Type “*.exe” as filename to search for
d. Click on ‘when was it modified ‘ option and select the specify date option
e. Type from date as 1/31/2008 and also type To date as 1/31/2008
f.
g. Now hit search and wait for all the exe’s to show up.
h. Once search is over select all the exe files and shift+delete the files, caution must be taken so that you don’t delete the legitimate exe file that you have installed on 31st January.
i. Also selecting lot of files together might make your computer unresponsive so delete them in small bunches.
j. Also find and delete regsvr.exe, svchost .exe( notice an extra space between the svchost and .exe)

5. Time For Celebrations
1. Now do a cold reboot (ie press the reboot button instead) and you are done.
I hope this information helps you win your own battle against this virus. Soon all antivirus programs will be able to automatically detect and clean this virus. Also i hope Avast finds a way to solve this issues.
As a side note i have found a little back dog( winpatrol ) that used to work perfectly on my old system. It was not their in my new PC, I have installed it again , as I want to stay ahead by forever closing the supply line of these virus. You can download it form Winpatrol website.
