This pc, and some more in my lan(20 pc's) have problems to navigate on internet, when I connect the lan cable (bandwidth) the pc's try to connect to some pages to download malware (a dealer), start to have ip conflicts and the pc's are not able to see other computers in the lan. Also a program is added with the name of dialer mon. Also can't get windows updates, and can't update my av and antispywares (spybot and addaware).
Already ran an av's on demand scann (in safe mode and disabling system restore), delete cookies, temp files of windows and ie, ran a registry cleaner (regcleaner).
Here is the log of hijackthis.
Thanks in advance for your help.
