It really is difficult to achieve a solution in the distance.
Sometimes when you update an antivirus or windows causing such failures.
First, check that your gateway is open, if you do not speak with your tea dira if it is open, and if you can not be opened. If the gateway is well make sure your anti-virus / spyware has enabled the door. It would be important to know whether the problem you have when the virus is activated.
Secondly, if a few days or weeks, the problem is not what tapeworms can return to restore the system to one day before they occur, it is possible that the problem will disappear.
Thirdly the spyware it seep into your PC causes the line to be shared, so they slow down any navigation. Make sure you do not.
Fourthly, you can install the bitcomet again, the latest version fixes some problems with upgrades.
I hope that this problem will soon solutions friend, and tell me how you will.
If they continue attempts dime and give you other solutions.
A hug and my vote.
