Using Flash Player 12

I have desktop Dell Windows Vista pack II Home Premium 32-bit. I have installed Flash Player since longback and got it updated. Currently it is F.P.12 version. Through internal software performance cheking with the help of DELL Security Centre, I became aware that FP12 is subject to crashes often. Moreover I feel delayed while downloading data from various sources for my day-to-day requirement. Please suggest me how I can stop crashing FP12.


I have a Vista Ultimate 64 bit SP2 machine with Flash Player in IE, Chrome and Firefox.  
No crashes.
Frankly, I wouldn't trust Dell Security Centre. Unless you actually see repeated crashes of Flash Player, it isn't crashing, in spite of what DSC may report.
