weird things in traffic with wireshark (mitm ?)


I’m searching a malware in my laptop but I’m not sure if it’s within or outside (I mean on the router). Anyway I started to capture the traffic from my pc with wireshark and I found really a lot of weird packets. They’re colored of black and are:

  • [TCP retrasmission] <— a lot
  • [TCP out-of-order]
  • [TCP Dup ACK]
  • [TCP Spurious Retrasmission]
  • [TCP ACKed unseen segment]

Those errors could be signs of some kind of mitm attack ?
