Hello. I am experiencing Internet connection problems after being infected with Internet Security 2012 virus. The virus is gone now, but I can't restore Internet connection. I am using Acer Aspire 7720z laptop with cable wireless connection through NetGear router. MiniToolBox and FSS logs follow.

Try downloading the wireless driver for your network card here, then uninstalling your current driver, and reinstalling again. This link is from their website. If for some reason it's not working, just go to your computer's driver page and download it from there manually. Scroll all the way down to the bottom, and under Wireless LAN, it's the fifth link down.

Thanks for your prompt reply. Unfortunately reinstalling the driver did not help. Any other suggestions what that might be?

It looks like a matter of correcting some settings....

Make sure, your settings are correct.
1. Go Start>Settings>Control Panel (Vista/7 users: Start>Control Panel)
2. Double click Network Connections (Vista/7 users: Network and Sharing Center)
3. Vista/7 users - From the list of tasks on the left, click Manage network connections.
4. For a wired network connection, right-click Local Area Connection, and then select Properties.
For a wireless network connection, right-click Wireless Network Connection, and then select Properties.
5. From the General tab (Vista/7 users: Networking tab), click Internet Protocol version 4 (TCP/IPv4), make sure it is checked, and then click Properties
6. Make sure Obtain an IP Address Automatically and Obtain DNS server address Automatically are checked.
7. Click on "Advanced" button and make sure "IP Settings" tab looks like this:
Posted Image
Make sure "DNS" tab looks like this:
Posted Image
Make sure "WINS" tab looks like this:
Posted Image
8. Still in Control Panel double click on "Internet options" then "Connections" tab then "LAN Settings" button. Make sure "Automatically detect settings" is checked.
If you made any changes OK your way out.
Restart computer.


If that doesn't work...
Turn off computer. Disconnect router, and modem from power source for 1 minute. At the same time disconnect ethernet cable as well.
Reconnect everything.
Restart computer.

If that doesn't work, bypass router, and connect computer straight to the modem.

If that doesn't work...
Go Start>Run (Start search in Vista), type in:
cmd
Click OK (in Vista and 7, while holding CTRL, and SHIFT, press Enter).

In Command Prompt window, type in following commands, and hit Enter after each one:
ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew
net stop "dns client"
net start "dns client"


Restart computer.

If that doesn't work...
Go Start>Run (Start search in Vista and 7), type in:
cmd
Click OK (in Vista and 7, while holding CTRL, and SHIFT, press Enter).

At Command Prompt, type in:
netsh int ip reset reset.log
Hit Enter.
Type in:
netsh winsock reset catalog
Hit Enter.

Apply Fixit from: http://support.microsoft.com/kb/811259/en-us

Restart computer.
NOTE for Windows XP users. You may need to apply manual fix from the above link.


If that doesn't work...
Download, install, and run WinSockFix: http://www.softpedia.com/get/Tweak/Network-Tweak/WinSockFix.shtml (doesn't work in Vista and 7)
Restart computer, and check again.

If that doesn't work...
Download Dial-A-Fix (DAF) (doesn't work in Vista and 7):
http://wiki.lunarsoft.net/wiki/Dial-a-fix#Mirrors.2Fdownload_locations.2C_and_articles

Have XP CD available in case DAF needs a file. Likely not!

Check all boxes on the screen (clear any restrictions if it shows any)
Then click GO!

When the entire page is finished click the HammerHead at bottom to go to the second DAF page.

Here, one at a time, do the below:

Reinstall BITS
Reinstall Windows Firewall
Repair Permissions
Reset networking

Watch for any File not found or other errors and make note as this may lead to the fix!

Restart computer.

None of the above methods helped. Do you think reinstalling windows will fix the problem?

Obviously something going on with your settings, or something is missing that is very hard to pin point. If you can reinstall, then like Broni said, it will most likely fix the problem
