RegCure - Fix PC Errors(Svchost.exe Virus Guide)

On occasion you may notice that your computer is running terribly slow. Curious to discover the problem you open up the task manager, and find something similar to the following: There may just be one svchost, or several – but combined they are bogging down your computer.

Some people report a single instance of svchost which takes up 99% of their computer’s resources – meaning a dead stop for everything else.
What’s worse is that when there are multiple instances of svchost they are often competing for the same memory space, meaning none of them get to finish what they are trying to do, and neither do you! Before you take the steps to repair svchost, it’s a good idea to understand how this program works and what it does.

Svchost.exe Virus Removal Guide

What is Svchost.exe Exactly?

Svchost is a shell program that is used to run many different services on your pc. These services are contained in .dll (dynamic link library) files, and run separately from other programs you may be using on your PC. The svchost file is required to run these files as there is no executable. The .dlls called by the svchost executable could be for automatic updates or other legitimate programs, or they can be used to mask less benign programs.
Since there are many different services required by your computer there could be several instances of svchost.exe running on your computer, and they could all be taking up different amounts of your computer’s memory. A problem tends to arise when one .dll can’t complete its task, which in turn bogs down the rest of the svchost programs.
Unfortunately, the svchost.exe is used as a favourite access point for viruses and other malicious programs, especially with Windows XP which has had serious issues with svchost in the past, although most of these issues have now been patched. However, if you see instances of svchost it is a good idea to run a virus scan, just to be sure that nothing has crept in.
Usually you will have a good indication that the svchost.exe is masking a virus or some other major problem when it is using 50% or more of your computer’s resources. The svchost can also become corrupted and cause problems when you install and remove programs, which shifts around the .dll files. So what do you do to fix svchost? While it’s a good idea to download a good registry scanner, you may want to do some more investigating to find the root cause of the problem before you begin.

Google voice video chat cant detect my webcam

Solution1

1. Close your browsers
2. Check where the plugin is installed: run regedit and go to
HKEY_CURRENT_USER\Software\Google\Google Talk Plugin key. Look for
string value "install_dir" - there you'll find a path to the plugin's
install path. Write it down! :)
3. Uninstall the plugin from Control Panel
3. Go to your install path
4. Delete uninstalled files: probably not everything was unistalled -
in my case a log file packed with bz2 extension was left and a
"googletalkplugin_port" file(!) - DELETE THEM!
5. Get a fresh copy (just in case :)) of Google video chat plugin
setup
6. Install the plugin once again
In my case it helped! :) Previously I have also reinstalled the
plugin
and even my browser many times and it didn't help. But deleting these
files helped. I hope after a system restart my video chat in google
will still be working! :)
Cheers!

Windows cannot find Explorer.exe

If your system was infected by the regsvr.exe or commonly known as newfolder.exe virus and if you have successfully removed the virus from your system, but still you may be getting this annoying error message during startup telling “Windows cannot find regsvr.exe” as shown below. You may face similar problems like “Windows cannot find explorer.exe” etc. This is because the virus had assigned a registry value to execute itself during the startup. As you have removed the virus, the system can no longer find this virus file and hence the error message.


This problem has a very easy solution. Just follow the steps below:
Step 1: Press Start+R and type regedit. It will open registry editor. But if you get an error like Registry editor has been disabled by the administrator then you need to enable the registry editor. To enable registry editor click: How to enable Registry Editor (REGEDIT).

Step 2: Now after opening the registry editor, follow the registry path as follows:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon
This path is also shown in the images below:

Step 3: After opening Winlogon look for Shell in the right pane of the registry editor as shown.

Step 4: Double Click the Shell registry value. You can find “Explorer.exe regsvr.exe” in the Value data field.

Step 5: Delete regsvr.exe alone and click OK.

Step 6: Now the registry has been changed. Closed all programs and restart.

After restart you can find that the message is no longer shown.

Windows cannot find Regsvr.exe

As you might have seen, whenever you face a virus attack the first thing it does is to disable the registry editor, task manager, folder options etc. In order to enable the last two you need to enable the registry editor first. Here I have given a simple solution for enabling the registry editor such that even a naïve will be able follow.

To open your Registry Editor press “Start Button + R” or go to Start menu and click RUN. Then type regedit in the run command and press Enter. If your Registry Editor opens then it has not been disabled.

Here is how it looks like when your Registry Editor has been disabled.

Follow the steps given below to enable your Registry Editor:

Step 1: Open notepad or any other text editor. Copy and paste the following code in the box to the notepad or you can download the regedit enabler file from the link below:

'VBS file to Enable Registry Editor' 'www.techrena.blogspot.com On Error Resume Next Set WshShell = WScript.CreateObject("WScript.Shell") WshShell.RegDelete "HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System\DisableRegistryTools" WshShell.RegDelete "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\DisableRegistryTools" Message = "Your Registry Editor is Successfully Enabled. Please Visit www.techrena.blogspot.com for more help" X = MsgBox(Message, vbOKOnly, "Done") Set WshShell = Nothing Set fso = Nothing

Or
Download regedit_enabler.zip Here Extract it and skip Step 2

Step 2: Now to save the file press “CTRL + S”. It will show a window for selecting the location and format of the file you want to save. In the “Save As Type:” List select All Files. Type your desired file name and add .vbs at the end of the file name. In my example, I have kept the file name as regeditenable.vbs. after typing your file name click Save.

Step 3: Now go to the location where you have saved the file. Open the file. In my example I have saved the file in my desktop.

Step 4: You will get a message box telling your Registry Editor has been enabled. Click OK.

Now you must have access to your registry editor. Go to RUN and type regedit.

After opening your Registry Editor you can now enable your Task Manager, Folder options etc. If you have any sort of problem please notify us.

Install Linux Fedora 11

Procedure: Install Linux Fedora 11 and GRUB when Windows 7 was installed first

Installing other operating systems on your Windows 7 computer may invalidate your warrantee.
It's very important to follow the instructions exactly as stated and that includes any restarts!

---

Requirements.

---

• Installation CD/DVD for Linux and preferably Win7's DVD.
• 1 download.
• A first hard disk that uses only NTFS and contains a working Windows 7.

---

A. Make your preparations.

---

1. Backup important data before making any changes to a partition. You can burn files to a CD, clone an image of your hard disk, copy files to a USB flash/pen/thumb drive, or use an USB external drive (a good choice)
2. Download Fedora 11, standard or 64-bit version from http://fedoraproject.org/. You can use the excellent free GetRight download manager to help with the large download. Create the Fedora Live DVD from the downloaded .ISO file.
3. Optional: Download NeoSmart's free Windows 7 System Recovery Disk if your Win7 DVD is missing!
4. Disconnect all external devices before you start.

---

B. Make free space (Unallocated) for Linux.

---

The single 160 GB disk usually used in testing initially had: System Reserved (100 MB, Primary, Hidden, NTFS), Windows 7 (150 GB, Primary, NTFS). The Windows 7 drive was shrunk leaving about 60 GB Unallocated space at the end of the disk (to the right). After repartitioning it had: System Reserved (100 MB, Primary, Hidden, NTFS), Win7 (90 GB, Primary, NTFS), Linux (60 GB, Unallocated).

1. Restart computer correctly (close all programs/software before Restart).
2. Open Disk Management in Windows 7 (right-click Computer, select Manage, click Disk Management).
   • Note which partition is marked Active.
   • Right-click the Win7 volume, and click Shrink Volume.
     • In Enter the amount of space to shrink in MB: enter enough for Linux and its Swap file.
     • Click the Shrink button (it may take some time!).
       Note that we are leaving the newly acquired free space as Unallocated.
     
     If Shrink does not give you sufficient Unallocated space, read Shrink the Windows 7 or Windows Vista Partition for instructions on how to complete this task successfully. Then return here.
     
3. Restart to Windows 7 two times.
   • Open Disk Management and check that the change made is correct.

---

C. Install Fedora 11

---

Raid/LVM was not an issue when testing so partitions were created manually during installation. Grub was installed either to the Linux EXT3 partition or to the MBR - both worked fine though the Linux partition is preferred unless you have specific reasons for overwriting the Windows boot sector and boot loader.

1. Bootup from the Linux Fedora 11 installation CD/DVD.
   Select Install or upgrade an existing system.
   • Continue with the initial screens until you're presented with the option of partitioning your hard disk
     (you can skip the testing of media - it checks your CD/DVD for errors).
     • Select Create custom layout in the top drop-down list and click Next.
   • Highlight the Free space, and click the New button.
     Add Partition will open. First create the Fedora partition.
     • In Mount Point:, select / (a forward slash).
     • In File System Type:, select ext3
     • In Size (MB):, enter all available space (for Fedora) except 1 GB (for the Swap File)
     • Click the OK button.
   • Highlight the remaining Free space, and click the New button.
     Add Partition will open. Now create the Swap partition.
     • In Mount Point:, leave it blank.
     • In File System Type:, select swap.
     • Tick to enable Fill to maximum allowable size
     • Click the OK button
       (it's fine if the Swap is made a Logical partition in an Extended partition).
     
     Click Next when ready, or click Back to recreate partitions.
     Then click Write changes to disk or Go back if unhappy with the changes.
     The new partitions will be created and formatted on the disk now.
     
   • The next screen is vital to ensure the correct location for GRUB's installation - read Installation Notes above.
     • If you wish to overwrite the Windows boot loader, leave the default at Install boot loader on /dev/sda or /dev/hda
     • If you do not wish to overwrite the Windows boot loader, click the Change device button.
       • Select First sector of boot partition and click OK.
     • Using a boot loader password is optional.
     • Under Boot loader operating system list,
       highlight the Device labelled Other and click the Edit button.
       • In Label, enter a name like Windows 7.
         Leave Default Boot Target unchecked unless you want Windows 7 to be the default on bootup.
       • Click OK.
     • Click Next.
   • Deal with the software applications screen as you think fit ("Customize later" is fine).
   • Click Next and the install process will start.
     
2. Fedora will reboot your computer once before installation is completed (remove the DVD).
3. Restart computer.
   Press the required key (within three seconds!) when you see Press ... key to enter the menu to access the boot menu.

How to Remove One OS from Dual booting ..

First boot up in the os you want to use
go to your c: drive
at top of screen, click tools, then folder options
this opens another window, at the top of the new window
click view, now scroll down and check show hidden files and folders then scroll down a little more and un-check hide protected operating files.
click apply and then ok

This shows a bunch of stuff you shouldn't play with so when your done, put the settings back.

now when you go back to your c: drive, you should see a file called boot (it will look faded out)
double click it to open it
you will see

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0) partition(number of partitions)\windows
the next lines will list the o/s you have loaded
just delete the lines you don't want and close the window
you will be prompted to save, click yes
carefull you don't delete the wrong one, if you do, it won't show on the boot menu and don't delete the default line
exit out of everything and restart windows

Oh and if that doesn't work, copy & paste that boot config file into the other partition(s) as well
I trust that you left the other o/s on a different partition
