my son recently updated adobe flashplayer which came up upon start-up,which i wasnt aware of,i have checked programs and features and in there i have the following: adobe reader 9.5.1 MUI,adobe flashplayer 11 ActiveX 64 bit,adobe AIR and acrobat.com,the reader was updated on the 14th of april this year,since then i have noticed my computer is sluggish and certain games on facebook are either slow or crashing,one game which i regularly use is now saying upgrade flashplayer.I am not sure if i should upgrade or not or if what my son updated is clashing,or even if i need all of these adobe on together,i do not know if i need all of those i have listed so i dont want to uninstall anything i shouldnt.I await your reponse and am hopeful for any advice you can give me on this matter.Thankyou jokat
