@OrlandoP I am hardly user of portable apps. I am usig on my 3 computers at home 40 portable application from portableapps.com. I have just installed Adobe Flash and an antivirus application after format Windows operation system. I just start all portable app I want from my another NTFS part of my computer. I just ask if possible to make also the antivirus as portable. But if you say it is not possible (or very difficult...) I can not say anythink...
Some people always asks me why do you use portable apps so much. I am answering it simply before anyone ask me :
-Windows is always getting slower after installing any new application
-Windows losts its stability after installing any new application
-Windows losts its secure after installing any new application
-I don't spend my time to install 40 application after each format on any computer (I know there are many stable backup applications for Windows but I the updates of each program after recover takes time and some apps lost stability with updates many times (overlap) ).
-Some application lost its stability when updates itself (always zero installation is better). That's why some apps unistall and than installs itself on each update.
-If any app losts it's stability, I dont have the possiblity to remove the user-data folder. (on portabele apps we have Data folder which includes all user-preferences...)
-and many other reasons that I will not write them here...
Thanks for you interest...
