Cannot execute any exe files

The message i get is something like this:
(this happens when i double click on the actual file, in windows explorer, not when opening it from a shortcut)

"Could not find the file c:\whatever.exe (or one of its components). be assured that the route and the name of file are correct and that all the libraries are available."

This happened after VirusScan found a virus, and deleted it.
The virus was in C:\Winnt\Fonts\csrss.exe.

The OS is windows 2000 pro, sp4.

Thank you,

joesatri

Another thing. For instance, if i try opening acrobat reader, i get the same message.  However, if i try opening a document, it opens correctly.

Also, this is a Virus Fix that re associates .exe files if they are stuffed up, but might save your bacon in this instance.

On the Windows taskbar, click Start > Programs > command. The command prompt will display the current directory, which should be the Windows directory. In most cases that will be displayed as:
C:\WINDOWS>

if not type "cd c:\windows {enter}" without the quotes


Type ren REGEDIT.EXE REGEDIT.COM.
Press Enter.
Type REGEDIT.
Press Enter.
Modify the following Registry value:
HKEY_CLASSES_ROOT\exefile\shell\open\command

and change

"C:\WINDOWS\SYSTEM\winsvrc.exe "%1" %*

to

"%1" %*

For clarity, these seven characters are the following: double quote, percent sign, the numeral one, double quote, space, percent sign, and asterisk. Don't forget the space.

Solution 1:

Click Start, Run and type Command
Type the following and then press Enter after typing each one:

cd\windows
copy regedit.exe regedit.com
start regedit.com  [or regedit.com]

Navigate to and select the following key:
HKEY_CLASSES_ROOT\exefile\shell\open\command

Double-click the (Default) value in the right pane.
Delete the current value data, and then type: "%1" %* [with quotes]
(ie., quote-percent-one-quote-space-percent-asterisk.)

Exit the Registry Editor and restart Windows.

Solution 2:

Download .exe File association fix from here:
http://www.dougknox.com/xp/file_assoc.htm
[To run the .reg files, again you will need to rename regedit.exe to regedit.com and run the REG file using "regedit.com filename.reg" parameter]

NOTE: Once set, update the definition files for your anti-virus software and scan the system for viruses.

Thx Peter, it worked :)

Although i couldn't open the command prompt, (neither from the RUN dialog nor from the start menu), i created a batch file.

echo boo!
cmd

so this opened the command promt, and it allowed me to open regedit.exe

Next, i changed the reg value, and it works now. Thanks for the prompt / complete answer. Points go to you.
