i installed dropbox the other day,and synced something to my account with macroVPN,and yesterday morning,i opened my dropbox account website in my office computer,(which hasnt installed client programme),and i deleted some files from my dropbox account,and when i opened my home computer at night, surprisingly, i found my computer changed! my windows theme changed,windows wallpaper changed,and even two icons on my desktop were gone! when i opened the "start menu",it was like i installed my system just now...coz many things were missing! and when i restarted my computer,it was back to normal again,i am really lost,i scaned my computer with kaspersky,but no virus or trojan found,has it something to do with dropbox or i was hacked? thank u
