Unhappy Well, great.

So our internet goes all funky and we have to connect a computer directly to the internet () to fix our router problem. It stays like that for a little while and the next day we wake up with trojans in our pants.

I just booted up my Dell Powerconnect 3024 switch and a nasty little surprise by the name of 0xDEADBEEF jumps in my lap.
After I powered it up, it kept turning off and on, so I decided to hyperterm into it to see what was going on. Here it is:

RDU Product coming up...

  CPU type is R4650 revision 0x00
  DRAM found is 16MB
  Testing DRAM...OK
  Initializing FLASH Memory
  Initializing PCI host bridge


Any idea what I can do..? Do I have to load new firmware on it or what? Or is it nice greyish blue doorstop?

Are you sure it's a trojan? 0xdeadbeef is the ipv6 test range... You may very well just have a hardware problem.
