Thank you , i just used ATF cleaner , but still not ok . Complementing , i have this problem since i started ADSL connection , 4 years ago . I still could access that site with dial-up connection until last year . I already tried other providers , other computers . Yesterday i tested the cblc.com.br 's DNS servers with howismydns.com , squish.net and dnsstuff.com . The results were not good , but for sure most of the users have no problem accessing it, as this is a very used site . Ironically this is the most important site for me and THE ONLY ONE i cannot access .
