My letest anroed mobile phone is showing this error message when I try Chrome or other browsers. Had downloaded one program for protection last night, which I heave already deleted. and tried system restore. but restore couldn't be done, because of antivirus. I have disabled firewall as well as anti virus now.I have wifi at home, its working fine with phone and other laptop.
My mobile is showing good connection with wifi, but no internet.
I tried connecting with cable, it gets connected but no internet.
