Do computer viruses affect all user accounts on a computer?

IF a virus affects a local user will that effect administrator account and vise-versa?

Viruses are all different and designed to do different things. The infection you were asking about in the other responder's message, "W32.Korgo.G", is actually a worm. It exploits a vulnerability in the LSASS.

After digging through some of the documentation on the worm at the Symantec site I can safely say this does affect all users on the machine.

Since it's a worm it may have affected other machines on your network as well.

This will depend on what the virus does.
But in most of the cases, it will affect all the user account. I cant go into more details without talking about a specific virus.

Thanks for the replay. If virus is of type W32 example: "W32.Korgo.G". will this affect all the user accounts? –  user229642 Jun 7 '13 at 6:43

A Virus in general does not depend on the user account. Maybe read in Wikipedia what a Virus is.

Maybe you are more relating to Malware that are often interested in information about the current user. An example is a trojan horse trying to get access to your computer with the information of the logged users.

So in general a virus does not depend on the user account and affects all the user**s. On the other hand a virus or **malsware often uses the information of the logged user. So another user account may not be affected by a malware, but can => depends on the malware/virus.

Thanks for the replay. Here i'm moving forward to remove the virus manually through regestry key deletion. Here consider the scenario of virus of type W32 example: "W32.Korgo.G". will this affect all the user accounts? will this creates registry keys in all the user accounts on the computer. –  user229642 Jun 7 '13 at 6:48
    
That Virus is not interested in user information and runs independent from the user. So the whole machine is affected and that means all users. See Symantec symantec.com/security_response/… –  FiveO Jun 7 '13 at 6:51
