Slow Computer and Error Message

Hi everyone,

I have a problem on my laptop which is making it run very slow. I have
Vista Home Premium.

I will admit to one thing, I removed Norton antivirus from the add/remove or
repair programs in the control panel. I then downloaded the free AVG
antivirus software and then installed it.

I have since been told that I should have downloaded the Norton removal tool
first then remove Norton then install AVG but I didn't. So I typed into the
start menu - Norton, symantec and live update and I deleted all the little
files that came up relating to those titles, there are still a few files
left that I cannot get rid of.

I am assuming it is to do with this but it may be not but my PC is
definitely running slower than it was before this action was taken.

I have also activated a backup and restore three times but this did not make
any difference.

I also get a message that appears when the laptop is started up.


Message that appears when laptop is started: -

FAILED TO CONNECT TO A WINDOWS SERVICE
Windows could not connect to the System Event Notification Service service.
This problem prevents limited users from logging on to the system. As an
administrative user, you can review the System Event Log for details about
why the service didn't respond.

Has anybody out there got any idea how I can fix this please?

Did you try a System Restore to a point before you uninstalled Norton?

That's a good answer.
If doesn't resolve it - I would uninstall AVG and then run the Norton
removal tool. It wouldn't hurt to then run sfc /scannow and finally,
reinstall AVG.

Hi Michael,

I am not sure, I think I did but cannot be certain on that. Perhaps I
should try again and report back.

What is sfc /scannow?

The other question I meant to ask was, when I downloaded the Norton removal
tool, I wasn't quite sure what version I had (which it asks for) so I do not
know if I picked the right one. My dad loaded it on there but cannot find
the disk or key number so is there any other way of finding out what version
I have?

re. sfc
That's a great link from the other poster re. sfc. One additional point -
in Vista this must be run in an elevated command prompt. (Right click on
command prompt and select Run as Administrator.)

re. Norton Removal Tool
The choices listed in
http://service1.symantec.com/Support...05033108162039
differ with respect to instructions they show re. preserving the license
information and reinstalling Norton. The executable file itself is the same
for all. Since you're not reinstalling there should be no issue.

Ok thanks, I have had a look at that, which one do I download? Will it work
with Vista which is what I have?

Ok GTS, I'll give it a whirl :-) thank you.

Hi, Gill.

A trick that often works for software that doesn't cleanly UNinstall is
to...install it again! When its installer runs, it (re)creates the
necessary Registry entries, plus any subsidiary files that the unsuccessful
uninstall may have messed up. After the reinstall, follow the instructions,
including the removal tool, in the proper order.

On your other question about sfc /scannow: SFC is for System File Checker.
This tests each of the core operating system files in \Windows, using
techniques such as CRC (Cyclic Redundancy Check) to verify that no bits in
the file are wrong or out of place. Any missing or damaged files are
replaced by original copies that have been saved in a cache on your hard
drive. These "originals" will have been updated by any Service Packs or
other hotfixes that have been installed. SFC MIGHT need to see your
original Vista DVD-ROM, so it's a good idea to have that handy. It usually
doesn't take more than a few minutes to run SFC, but it can sometimes take
longer, so don't get too impatient.
