Acrobat 7 e windows installer, explorer.exe

[meeeuri]

ciao a tutti
1° problema: explorer.exe, durante l'utilizzazione del pc, aumenta l'utilizzazione della memoria fino a livelli assurdi (200 Mb e oltre, solo per questa applicazione), in particolare se cancello file o cartelle o cmq durante l'uso del pc, costringendomi ad un certo punto a riavviare. notare che ho un problema analogo con skype che, se connesso, aumenta il file di paging fino a bloccare tutto.
2° probl: quando apro una cartella o avvio ie compare una finestra di installazione windows installer e anche acrobat 7, il risultato sembra sia la creazione di una cartella "acrobat" nei documenti condivisi. se la cancello si ripete il fenomeno. ho letto da qalche parte di problemi di sicurezza di acrobat 7, ho cercato di scaricare le patch di sicurezza ma non ci sono riuscito.

qualche consiglio???
grazie
