Recently purchase BD total security 2013 and it seems to be runnig fine on my windows 7 system if a little slow on startup. However i installed it also on my sisters dell inspiron running xp and it has slowed down completely. It now takes like 4 minutes for her laptop to startup and once open it takes forever for firefox to open with no other programs running.Any suggestions would be helpful. Not sure what other info ye might require so please llet me know and i will do my best.
