attack to exploration port TCP

[PachaQtec 0]

Hi, everyone.

Since I moved to Brazil and I'm in a Coliving room, my Internet security Antivirus alert me about a (possible) attack to my PC. The licence of my antivirus is OK, but how do I know if it is really an attack to my computer by someone of my coliving roomates? Should I be concerned about the security of my other devices(smarthphone and tablets)?

Somebody was performing a port scanning. It could be for legitimate reasons if it was done by an administrator.
