I have said that svchost exe is a vital part of your system and should not be removed but be reminded that there is also similarly named file like the scvhost.exe which is not a system file but a kind of worm malware programs.

This malware usually spread through Yahoo Messenger. So, accepting invitation from unknown friend is one sure way to get infected with this scvhost.exe virus. What does this virus do is that it disable or blocks the Task Manager and also the Registry Editor and install itself in the autorun.inf file. The malware spreads by copying itself in the shared folders and then remotely install itself in the registry.

Registry Editor opens, now look for this startup key: HKEY_CURRENT_USER\Software\Microsoft\Window\CurrentVersion\Run. then delete the Yahoo! Messenger entry with the value “c:\windows\system32\scvhost.exe“.

7. Find this key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon and then edit the “shell” entry with the value “explorer.exe, scvhost.exe” into “explorer.exe“.
