Hi i have a laptop which although boots fine and is connected to the internet via wireless connection, will not log on to any page.The laptop is an Acer 6935 and i have tried to reset back to factory settings but the Alt F10 doesn't work.Any windows troubleshooting access is also denied.I think the problem may be do to me downloading comodo internet security 2013 as these problems have accured after this.I've tried to remove the programme but it just gets stuck half way through.Any help would be great.john
