Hello,

In that case, i suggest you to remove the hard drive and connect it to other computer which has a potent antivirus and scan. You can use the online scan here: http://www.precisesecurity.com/antivirus/online-scan.htm

But most likely if the system is infected with virus, virus can be deleted but the system is slower ..guess reformatting and and windows installation is the best way.

pls do not rate me if my solution not solve the issue and you need more further information. but if is invaluable solution rate me fixya.

best regards, melnavz

Find proxy server address


Changing TCP/IP settings Win 7 TCP/IP defines how your computer communicates with other computers.
To make it easier to manage TCP/IP settings, we recommend using automated Dynamic Host Configuration Protocol (DHCP). DHCP automatically assigns Internet Protocol (IP) addresses to the computers on your network, if your network supports it. If you use DHCP, then you don't have to change your TCP/IP settings if you move your computer to another location, and DHCP doesn't require you to manually configure TCP/IP settings, such as Domain Name System (DNS) and Windows Internet Name Service (WINS). To enable DHCP or change other TCP/IP settings, follow these steps:
  1. Open Network Connections by clicking the Start button 4f6cbd09-148c-4dd8-b1f2-48f232a2fd33_818.jpg, and then clicking Control Panel. In the search box, typeadapter, and then, under Network and Sharing Center, click View network connections.
  2. Right-click the connection that you want to change, and then click Properties. 18abb370-ac1e-4b6b-b663-e028a75bf05b_48.jpg If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
  3. Click the Networking tab. Under This connection uses the following items, click either Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol Version 6 (TCP/IPv6), and then click Properties. 25e7e385-9327-4f7d-aab0-afa5aaf952ba_49.jpgThe Network Connection Properties dialog box
  4. To specify IPv4 IP address settings, do one of the following:
    • To get IP settings automatically using DHCP, click Obtain an IP address automatically, and then click OK.
    • To specify an IP address, click Use the following IP address, and then, in the IP address, Subnet mask, and Default gateway boxes, type the IP address settings.
  5. To specify IPv6 IP address settings, do one of the following:
    • To get IP settings automatically using DHCP, click Obtain an IPv6 address automatically, and then click OK.
    • To specify an IP address, click Use the following IPv6 address, and then, in the IPv6 address, Subnet prefix length, and Default gateway boxes, type the IP address settings.
  6. To specify DNS server address settings, do one of the following:
    • To get a DNS server address automatically using DHCP, click Obtain DNS server address automatically, and then click OK.
    • To specify a DNS server address, click Use the following DNS server addresses, and then, in the Preferred DNS server and Alternate DNS server boxes, type the addresses of the primary and secondary DNS servers.

Can't find scanner


Is the scanner visible in Device Manager? If not you have a hardware or connection issue.

Is the connection USB or network? If network have you checked TCP/IP settings? If USB are the USB items OK in Device manager?

Is it an old scanner connected to a new Windows version such as Win7. Some old scanners are not compatible.

Don't have permission to access on this server


Sounds like you are going to a site that you are not supposed to be on. Maybe some settings are off and taking you there.

Let's start with Internet Options. If you have Windows XP Click Start/Control Panel/Internet Options. If you have Windows Vista or Windows 7 click Start/Control Panel/Network and Internet/Internet Options.

When the Internet Options window opens on the General Tab make sure you have a valid web address as the Home Page. If not, create a simple Home Page by typing: http://www.google.com You don't have to click OK now because if you do the Internet Options window will close.

Click the Security Tab and under where it says "select a zone to view or change settings" Click on the one that says Internet, then scroll down to near the bottom right and make sure that DEFAULT is grayed out (whereas you cannot click on it). You can Click on Default just to be sure. Next click the Intranet so that it is highlighted and make sure DEFAULT is grayed out so that you cannot click on it. Do the same thing for the other two zones (Trusted Sites and Restricted Sites). After all zones under the Security Tab are set to Default click the next Tab which is the Privacy tab.

On the Privacy Tab you want to make sure that DEFAULT is grayed out, if not click on it. When in doubt just click the Default tab.

Next skip over the Content tab and proceed to click the Connections Tab. On the Connections Tab make sure that the Never Dial A Connection is checked if you have something in the white box above it in for Dialup and Virtual Private Networks settings. Look down on the right near the bottom and Click the LAN SETTINGS button. When Lan Settings open up the only box that should be checked is the very first box that says: Automatically Detect Settings. If any other box is checked remove the check from it or you will never be able to connect. Click OK to close the LAN SETTINGS tab.

Next skip over the Programs tab and click the Advanced tab. When it opens slide the blue bar on the right all the way down until you get to the bottom of the window. You want to be able to make sure that if you see something like (Use SSL 2.0, Use SSL 3.0, Use TSL 1.0) that you put a check in the box to the left of each one of them. Afterwards you can click OK to close the Internet Options Window.

Next lets go boot your computer in Safe Mode.
Go to www.google.com and in the search box type:"Download cnet Malwarebytes" (without the quotes). Download and nstall malwarebytes from the sites download.cnet/malwarebytes. When thesite opens up click on the Green Download button on the left. Do not click the Red Download button, that's junk. When it finishes installing the Gui Interface will open up with an offer to Accept a Trial Version o Decline. CLICK DECLINE you want the totally free version. Run a QUICK SCAN. As it scans, if it finds infections the number will be in red. When it finishes scanning, click SHOW RESULTS. A notepad text document will open up showing you the results. You can close the text document and go back to the Gui Interface where you will click REMOVE SELECTED RESULTS. The objects will already be selected for you. When it finishes removing the objects click ok and it will sometimes reboot your machine.


Check your Network Settings for TCP/IP (you might have TCP/IPv4 and TCPIP/V6 if so check both of them).


For Windows XP below:
Click Start/Control Panel/Network Connections then Right Click on the Wireless Network Connection and select Properties. When the Properties window open click the Networking tab. Find the Protocol (TCP/IP) in the drop down window that says "This Connection Uses The Following Items" and Double Click on it to open it. You should make sure that you select Obtain IP Address Automatically and Obtain DNS Server Address Automatically. Click OK.

For Windows Vista below:

Click Start/Control Panel/Network and Sharing Center then look to the left of the open window and click Manage Network Connections. Right Click on the Wireless Network then select Properties. Find the Protocol (TCP/IPv4, TCP/IPv6) in the drop down window that says "This Connection Uses The Following Items" and Double Click on it to open it. You should make sure that you select Obtain IP Address Automatically and Obtain DNS Server Address Automatically. Click OK.


For Windows 7 below:
Click Start/Control Panel/Network and Internet/Network and Sharing Center then look to the left and select Manage Network Connections. Right Click on the Wireless Network then select Properties. Find the Protocol (TCP/IPv4, TCP/IPv6) in the drop down window that says "This Connection Uses The Following Items" and Double Click on it to open it. You should make sure that you select Obtain IP Address Automatically and Obtain DNS Server Address Automatically. Click OK.

Why does the facebook could not be open?


Hi,

This problem can occur if there is a mismatch between the configured IP addresses in the Advanced IP Addressing dialog box and those listed in the Server Properties dialog box for the DNS server. This problem can also occur if the TCP/IP protocol is not bound to the network adapter.

User Action:

Verify that the TCP/IP addresses configured in the Advanced IP Addressing dialog box match those configured in the Server Properties dialog box in DNS Manager: 1. Open Control Panel, and double-click Network. 2. Click the Protocols tab, and click TCP/IP Protocol in the Network Protocols list. 3. Click Properties, and click Advanced. Match the IP addresses to those displayed on the Interfaces tab of the Server Properties dialog box in DNS Manager: 1. In DNS Manager, right-click the DNS server name, then click Properties. 2. Click the Interfaces tab, and compare the IP addresses with those from the Advanced IP Addressing dialog box. 3. Repeat steps 1 and 2 for all DNS servers configured in DNS Manager. If there are no IP addresses configured in the Advanced IP Addressing or on the Interfaces tab of the Server Properties dialog box, enter the IP address of your network adapter. Use the ipconfig -all command at the command prompt to obtain your IP address. Check the binding of the TCP/IP protocol to the network adapter: 1. Open Control Panel, and double-click Network. 2. Click the Bindings tab. 3. Verify that the bindings for all protocols to network adapters are enabled, and that no broken connections exist in the stack.

    Webpages are not being displayed


    It is not a problem with your wireless, it is a problem with your Windows installation. Here are two things to try...

    1. Run some sort of registry repair program. - Glary Utilities is a good free one, CCleaner is free and does reg stuff.


    2. To reinstall TCP/IP, you can Remove your Network Card in the device manager, then reboot your computer. When it reboots, it will redetect the NIC and install the drivers, including the TCP/IP transport protocol. I very recently dealt with this problem, and the registry repairs fixed it.

    Keep me posted...
