hi, i had 22 months smart license remaining when i upgraded to windows 7 64 bit in that time i have briefly use nod 32 v4 (regular) and even briefer smart v4.2 beta, the remainder of the time i have used MSE. problems have been with slowdown while browsing, problems using sites that use flash, on nod 32. general internet connection nightmares with on line games with pretty much any version of smart. i feel i have been more than patient, am i stuck with a license for unusable software? oh and i get the memory use thing if pc is left on also. i dont care if this is a microsoft problem it doesnt happen with vipre or mse.
