Hi
recently i installed windows 7 x64 home premium , and bitdefender Antivirus Plus with zonealarm free firewall . everything was good , but from yesterday html pages will open slowsly , i mean whole page must be loaded to display . many websites are like this . some download links like pdf files will be download full and then at once from 0% i will see 100% after minutes.
what`s the problem ? what i must do to remove the issue ?
