A short diagnostic checklist and practical next steps based on the symptoms you posted. reports a startup warning plus an inability to run .exe files or open RegEdit. That combination almost always points to a Windows-level infection that has altered .exe handling or blocked registry/tools — but first check whether the warning appears before the Windows logo (pre-boot) or only after Windows starts. If it is pre-boot, treat it differently (contact the vendor). If it is inside Windows, try the steps below.

Immediate triage (do these first)

  • Disconnect network and remove USB/external drives to avoid spread.
  • Boot into Safe Mode (F8 on Vista/7) and open an elevated Command Prompt if possible.
  • From an elevated prompt, export keys before editing, try to unhide files and remove registry locks, then restore the default .exe association. Example commands to run as Administrator in Safe Mode:
    
reg export "HKCR\.exe" C:\dotexe-backup.reg
reg export "HKCR\exefile" C:\exefile-backup.reg

attrib -s -h C:*.* /S /D

reg delete "HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System" /v DisableRegistryTools /f
reg delete "HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System" /v DisableRegistryTools /f

reg add "HKCR.exe" /ve /t REG_SZ /d exefile /f
reg add "HKCR\exefile\shell\open\command" /ve /t REG_SZ /d "\"%1\" %*" /f
reg add "HKCR\exefile\DefaultIcon" /ve /t REG_SZ /d "%1,0" /f


If those commands succeed, reboot and re-test. Do not run downloaded installers until the system is clean.

If Safe Mode tools are blocked
- Boot from clean media (Windows install USB or a trusted Linux live USB). Copy personal documents/photos only (do not copy executables or installer packages).
- Scan those data files from a known-clean machine before copying back.
- Use an offline-scanning environment from a trusted source to remove persistent malware.

If repair attempts fail, a factory-image restore or full OS refresh from Dell is the reliable final option — @Temmu pointed toward offline scanning and @guybo noted a full recovery as a last resort. Always keep a verified backup of your personal files before doing any destructive recovery.

When all else fails, it may be time to go nuclear. Hopefully you have little or no data on this "new" machine. Format the hard drive. Reinstall operating system and whatever programs you have and start fresh. I know of no virus that can survive a full format.

If you can get online, google free virus scan and follow instructions for either "House Call" or a remote scan from Symantec (Norton). By scanning from outside your machine the virus inhabiting yours has no place to hide.
