I run Windows XP machine and have problem with internet traffic blockage every hour. I may play game online or listen to online radio and loose connection every hour.
First I thought it is my ISP, but then this will not will happen based on their own timing not based on timing my machine been started. So I moved with my suspicion toward anti-virus. Again wrong, anti-virus check fr update every ten minutes not every hour. Therefore I made some recording with Wireshark. I the recorded logs I found inciminating time when it happends, but unfortunatelly I can not identify which application casued this. Can somebody guide me please?
