I've been using a mega 105wr router to connect to the internet using default settings with wireless enabled. I figure someone hacked my pc and tampered with my file permissions. Everytym i view options for security permissions theres a group that flashes for a second then dissapears. At the time i had made the mistake of using outdated antivirus software but since then i've reinstalled windows, install virus scan,and turned off wireless. There are still intrusions through my router to my files.
