Aadi Hi, My PC seems to be under attack of a virus/Trojan/Malware. Everytime I connect to Internet, some process try to connect to the IP address 193.105.207.151. I have installed Malwarebyte's Anti-Malware. every time it shows me the popup saying it blocked access to the site 193.105.207.151. Google Chrome has been crashed as well but I can run IE and Firefox. As soon as I open IE or Firefox I start getting this popup from Malwarebyte's. I have latest version of Mcafee and Malwarebytes but none of them could find any virus/trojan definition in my system. Here is my System Info OS Version: Microsoft ark.txt Attach.txt DDS.txt mbam_log_2010_09_25__12_07_24_.txt defogger_disable.txt
