Server,
Workstation,

TCP/IP NetBIOS Helper.
Sto se firewalla tice, ako ces da delis failove sa komsijom, nema mnogo svrhe. Ako pustis njega da ti pristupi racunaru, moci ce i svako drugi (posto sve ide preko jedne mrezne karte). Ako komsija ima dobar i dobro podesen firewall, onda tebi firewall i ne treba. Naravno, trebace ti i antivirus (recimo AVG, Avast, NOD32...), i neki anti-spyware. Verovao ili ne, Micro$oft AntiSpyware je dobar
narocito ako koristis Internet Explorer za surf. Pored njega instaliraj i AD-Aware.
Redovno update-uj definicije virusa i spy/ad-warea. I,
ukljuci Automatic Updates za Windows!!!
Srecno
