Sometime ago I was infected with Trojans and although quite a lot of cleaning up has been done but the following irritants still remain.
(a) Along with my own DNS address ,an unknown DNS address 220.127.116.11:18.104.22.168 still appears in hijackthis log even after repeated deletions and
(b) In a few cases my browsers gets redirected to porn sites.
2. I am not particularly disturbed by (b) because on most sites I can operate satisfactorily and the windows do not create any nuisance.
3. My present query relate to the unknown DNS address. I am interested in finding what does this unknown DNS address do ??. Is it listening in ?? or what ??
4. What really happened when the infection took place was that the Zone Alarm gave out an alert message that ipconfig.exe wants to access the internet. Foolishly, I not only clicked "yes" but also placed a check mark in the check box.
