Hi , I'm new here and from what i already read on this forum seems like it is very helpful and friendly. I have this problem which i've been trying to solve for days now .. I'm on DSL cable, my pc is sitting behind a trendnet router/firewall..I's a home network with two pcs attached..I noticed that whenever the other pc is connected to the internet my connection becomes very active even without doing any online activities..I downloaded Comodo firewall and it seeesm that "svchost" is receiving data all the time on relatively high rate around 10 K/sec. My line is 128 K ... Ran every virus scanner , spyware removal .. etc . my Pc seems to be clean . My Question is : is this normal ? or does it mean that my friends pc on the network is infected ?
