i'm new to this kind of community.. so i don't know what to do.. i've been trying for months now. i'm having the same problem.. sometimes.. my taskbar changes to classic then you cannot connect to the internet and the sound is disabled. if i restart it.. it goes back to normal.. but eventually my taskbar will change to classic again..
i followed what is said in user punitmanik's thread (http://www.daniweb.com/hardware-and-software/microsoft-windows/viruses-spyware-and-other-nasties/threads/363540) up to the combofix.. when i ran the combofix... it said that "rootkit activity was detected and reboot is needed" please if you can find time to help, i'd gladly appreciate it. thanks
