Hi. I noticed that my computer is sending up to 1 Giga of data per day, even when idle!! and it downloads also big amounts of data when nothing is active. I tried Malware Bytes Anti Malware, Spybot S&D, Avira Antivirus scan. From McAfee : anti rootkit and getsusp (get suspected) and stinger. I ran Emisoft emergencykit (in safe mode too), tdsskiller, adwcleaner, sophos Virus Removal Tool. To view the traffic, I use networx_portable (http://www.softperfect.com/products/networx/manual/?lang=French) and TCPView (in which I see often a connection to akamai.com, but I don't have a akamai program). I installed Zone Alarm Free and even when I refuse all connections to any program, the traffic continues to flow at the same big rate. For a permanent protection, I have Super Anti Spyware and Avira antivir free and Winpatrol and Zone Alarm. I have run Combofix, although I read a bit to late not to do it without express advice. I cancelled what it did (no more internet connection after running it) with system restore plus the Combofix Erunt backup. But up to now, nothing has lead to an improvement.
Do you have an idea of the source of the problem ? Thanks a lot for any answer or guidance.
