How to remove rvhost.exe virus/malware from pc?

RVHOST.EXE Is most commonly caused by a worm infection.You shouldn't continue to get this threat once it's deleted, unless you come into contact with it again. May I suggest using caution with flash drives, and dont open things that you are unsure about. RVHOST.EXE also means A lot of viruses/worm sit in RAM, the registry and System Restore.


Solution no.1

First of all turn off System Restore by right clicking on ‘My Computer’ > Properties > System Restore. Now enable “Turn off system restore on all drives” > click apply > click OK.

Reboot your computer in Safe Mode – (achieved by pressing F8 continually during boot up) this should clear out the viruses in RAM and the registry. Now run your anti virus software and delete or quarantine any viruses found.

Reboot your computer in normal mode and complete another virus check. If all comes back clean turn on System Restore.

Solution no.2

Delete these files if they exist:

C:\WINDOWS\SYSTEM32\RVHOST.exe
c:\windows\rvhost.exe
%all drives%\new folder.exe
C:\Windows\Tasks\At1.job
Go to HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Run in the registry, and you need delete the entries which contain RVHOST.exe in them, or better yet, change them back to their appropriate paths.
Go to:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Policies\System
"DisableTaskManager" = 1 (CHANGE IT TO 0 )
"DisableRegistryTools" = 1 (CHANGE IT TO 0 )

Go to:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Policies\Explorer
"nofolderoptions" = 1 (CHANGE IT TO 0)

Go to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Schedule
"attaskmaxhours" = 0 (CHANGE IT TO 24)

Because this threat may make it unable to access the registry editor, you may need to Merge a .REG Program.
