flashback OS X 10.5.8

Have been having some issues lately and just read about flashback. I saw a patch was available, but only for more recent OS, not 10.5.8. I do keep getting an Adobe pop up, so that is why I am suspecting flashback. I'm computer illiterate. I use mine for email, Word documents, photos and iTunes. So any suggestions welcome - particularly if they are presented in a manner that a 6 year old could understand.
