Why PCGuard is Rubbish For XP
 

PCguard is set up for vista, not XP.
1. The greed for resources (where it scans for prob 40-50 mins per hour using around 40% processor time) is very noticable if you have only a single processor.
2. The 'Sidebyside' source error log43's (in the event viewer) are caused by Vista having (and XP not having) C++2005.
3. The 1000+ items in the Startup Program Group (in Windows Help and Resource Centre) are there because Vista can shuffle around system files and folders in a way that XP cannot.
VirginMedia let people imagine pcguard is ok on XP - no warnings - but it is crap for XP without multiple processors.
ANYONE who installs pcguard on an XP machine will suffer these problems.
Virgin ought to warn people about this.
