I read in the latest bigpond newsletter about a site that can detect and aid in removal of parasites sucking on web browsers. The url is
http://doxdesk.com/parasite/ - it's seems real enough indeed and it detected 2 parasites on my system! The nasty vermin had been causing pesty ad popup's and instability where IE kept crashing out - even after upgrading to XP
One parasite i got from installing audio galaxy satellite
after i removed the parasites, now my system is stable again, and no more ad popups!!!!
: D
browse to the above url and see if your system is clean
