Unable to open gmail and orkut

hello

i have this problem regarding gmail and orkut . Where i have tried with firefox and and internet explorer 8 also non of site is blocked by ISP ..Where i can access orkut via some other site but not with address ...some one please help

Did you tried some hack to stop ad-wares because i had this problem when i did changes in to \WINDOWS\system32\drivers\etc there with hosts file. go there open this host file in notepad an check that orkut and gmail is present or not ..if present then remove it and save it restart pc and try

Looks like some dns problem so its an ISP problem. I used to face this with some sites where sites did open with web-proxy but not directly.so i called ISP and they solved my problem so better to contact ISp. also make sure u have not done any thing wrong for that google ban you

First check for virus and malware use good antivirus and Malware Removal tool als try Spybot all are good for security then check for any firwall stting that way be blocking this sites else try this : go to start > run> type cmd > type ipconfig/flushdns
