XP Home Programming Bug or Virus After Effect

P

Peter Jam

I posted a similar question at 132933 and didn't get a satisfactory
answer, so I am changing it slightly.

Is it possible that a virus\trojan\spyware can corrupt or remove
administrator users permissions or rights to prgrams and files?

I have been working on a friends computer with XP Home that let the
Norton Antivirus lapse and probably got a virus. He downloaded McAfee
and tried to install it with NAV 2002 still on there. Then he tried
the Free version of Zonealarm 5.0 in combination with his Norton
Antivirus 2002/Mcafee.

For some reason this has proven disastrous to some users and not
others. The fix is to remove ZA 5 and install ZA 4.5.
My problem is this: All three Administrator users as well as the
Administrator in "Safe Mode" Get: "You do not have access to change
system configuration", or very similar. I finally gave myself
"Permissions" to Zonalarm in the registry and was able to uninstall it,
but I could not completely uninstall the NAV2002 or re-install it due
to lack of "Rights".

I found the file settings.liveupdate which according to Symantec I
should delete to successfully re-install NAV2002, I could not delete it
in any many. Logged in as Administrator I didn't even have access to
the c:\documents and settings\all users\ in "Safe Mode Command" prompt.
When I looked in the registry for that file and right clicked on
Permissions NO ONE had access. I gave the Administrator Access,
rebooted to no avail.

I created a new Administrator User and he didn't even have
access to the Programs?? I went into Control Panel and noticed that
almost all the users had a red X instead of their Icon, so I tried to
change one and I got a Class error and the report saying I did not have
priveledges to edit the icon.

I tried doing an Upgrade Re-install of XP Home, which even required
Re-Activation?

In my Internet searches for answers to this lack of "permissions" I
find many, many people who do not have access rights even though they
are Administrators.

Or is this just a Programming Bug in XP Home?

I finally formatted and re-installed windows XP Home last night, after
struggling for two weeks with this problem so am still very interested
in what is going on here??

Q. "Is it possible that a virus\trojan\spyware can corrupt or remove
administrator users permissions or rights to programs and files?"

A. Yes, a virus can change permissions and corrupt an operating system
severely, that's why it is vital to install a good up-to-date antivirus program.

Q. "Or is this just a Programming Bug in XP Home?"

A. No, it's the fault of the virus file that maliciously altered the registry.
