When
turning off my PC, Windows XP SP3 with
Virgin Media PC Guard Total AV Suite, I got a popup box titled
'Uipopuphidden' stating that I would loose all unsaved data if I closed it. This box only appeared when I replaced my AVG 8.0 with PC guard 6 weeks ago. Also since Saturday 30th May, my optical mouse pointer has been jerking around the screen/freezing.
SOLUTION:I telephoned VM this morning and they confirmed that
Uipopuphidden is SPYWARE, instructed me to uninstall PC Guard and reinstall it to Fix the problem. I have done so, and now when I turn off the PC everything appears to be OK. My mouse pointer is behaving normally.
I have posted here in addition to other PC forums where the problem was still unresolved within their postings.
