How do I fix my computer using command prompt, as this is the only thing I can get into. Please help?

Question

Pretty sure my computer got a virus. Once I turn my computer on he comes up with this message: this application has failed to start because iertutil.dll was not found. Re-installing the application may fix this problem.
Nothing else show on my screen except desktop picture. I press crtl +alt delete to get task manager up and somehow managed to get command prompt up. Can anyone help me please fix the problem.

Answer 1

If it only show your desktop picture which means that the program file which is required to show icons and other stuff ( explorer.exe ) has failed to run on your computer. It might be because of the absence of that iertutil.dll file. You ll have to download iertutil.dll file manually from the internet and place it in C:\Windows\System32 folder. This might solve your problem.



First thing you have to do is to check whether you can run explorer.exe in your computer or not. To do that get the task manger and on the file menu click New Task (Run) and type explorer.exe and then click OK. It might load the explorer so you would be able to fix your problem like I explained above.



If it's not gonna help try to get the dll file to flash drive using another computer and copy it to the System32 folder using the 'copy' command in your command prompt.



Hope this might help you.

Answer 3

You can download ccleaner for free here: http://bit.ly/1Bk5V5C



First open CCleaner

Go to the Cleaner tab and you will be confronted by a very confusing lineup of checkboxes.

To make this brief, below is my recommended setup:

Under internet explorer check temporary internet files, cookies, and last download location. Most users don't really need this stuff. keep history and bookmarks unchecked, history is a maybe, but you don't want to lose bookmarked sites. You can normally leave Windows Explorer, System, and Advanced alone.

Run CCleaner and it will start deleting files.

afterward it will present you with a list of the files deleted, you really don't need to go through it as it will be several pages long.

The registry cleaner is recommended for slightly more advanced users. Use it after uninstalling programs as they will often leave behind incorrect registry entries.

If you decide to run Registry cleaner then review the items detected and always back up the registry (I keep a folder aside for this)

The Tools tab lets you uninstall programs and set startup programs. Why do you need this if Windows has all of these features? Especially with Vista Home Ed. The windows defender software explorer( startup programs) doesn't pick up some entries (however software explorer is easier to use).

Using CCleaner to uninstall programs and then check for leftover registry entries takes less time.

Under Options you can determine how CCleaner cleans your files. I leave this alone.

Answer 4

Use recovery manager to restore to a previous point.
