Paranoia or something more sinister?

Hi All

I believe I may have a few internet security issues that I'd like to run by
you guys –

I have performed a number of professionally assisted operating system
reinstalls, upgraded Norton Security to 05, I’m operating Service Pack 2 and
also use Microsoft AntiSpyware, Search & Destroy and a Windows Firewall.

I also like to ensure I am closely observing generic security advice and
practices and applying basic common sense (- eg: windows passwords are
changed intermittently, regular and comprehensive security scans are executed
on a regular basis, password protection for "sensitive" info within Outlook
and Word is used and I aim to minimise any time spent logged on with
Administrative rights.

However, despite the above, I continue to experience issues that cause me
some concern. These are as follows -

* The Task Manager "Users" tab displays an old username that I used PRIOR to
full system reinstalls

* Sluggish navigational performance – (eg, desktop icons lagging while
populating)

* IE browser & Word forms changing size – and I don’t believe at my doing

* I don't seem to receive any notifications or Intrusion Detections
regarding random security breach attempts from either Norton or Search &
Destroy, as I have done in the past when I've been online for reasonably long
periods of time and/or navigating around less reputable sites

* When attempting to log off I often get the following prompt – “Other users
are currently using this computer. Logging off may cause them to loose data,
are you sure you want to log off?”

(I do not and have not ever operated a LAN and I am aware of issues others
have noted that are suspected to have been compromised remotely?)

* The mouse often moves across the screen without me operating it - at
first, I put this down to the nature of an aging infrared mouse - however,
this is occurring more and more frequently

* The clicking sound of a mouse pointer in action - when I am not touching
any parts of the computer or running any operations that could cause this to
take place

>From observation of any the above - does anything stand out that would
indicate to you that my PC security may still be at risk? If so, what should
I do that I'm not
already doing?

I'm hoping it's all just a healthy dose of paranoia - please let me know if
you suspect otherwise and what you would recommend?

Any help here is much appreciated!

Kind Regards
Damien
