so i downloaded this program to give attempt clearing up some ram. im not really sure it did any of that but it definitely added over a gig of data onto my already tiny hd.i have an HP Stream 14 touch. it came with a 64gb drive. i have a slave drive but i still run windows off the internal so im always cautious about installing anything. about 5 minutes before installing avast i had 11.x available. after running avast i had 9.x available while its telling me it cleared this space.
