Hi

My daughter got a Security Shield virus on her laptop and I managed to remove it using this very helpful BC thread:

http://www.bleepingcomputer.com/virus-removal/remove-security-shield

The laptop uses Windows 7.

The removal seemed to work fine, although one slightly odd thing (compared to the thread's advice) was that I didn't have to change the LAN settings/Proxy server when I booted up in Safe Mode - the virus was preventing internet access but didn't appear to be doing so by the Proxy server change.

So I was able to access the internet perfectly well when in Safe Mode with Networking. I downloaded everything I needed using the laptop wirelesly and scanned/removed the 2 security shield virus files using malware bytes. Then, when I rebooted as normal in order to complete the process and update the HOSTS files, I couldn't access the internet wirelessly. The router is working fine and when I connect via ethernet cable the laptop communicates fine with the internet. It just refuses to let me connect wirelessly.

I have tried:
Checking all firewall options in McAfee (though I guess this wouldn't enable a wired connection either if it was the problem)
Removing and reinstalling the wireless device (via device manager)
Deleting and resetting up the wireless profile

Just not sure what to do next....

Any advice appreciated!

Thanks

Rich

Hi Rich -
Please download Farbar Service Scanner and run it on the computer with the issue.
•Make sure the following options are checked:
  • Internet Services
  • Windows Firewall
  • System Restore
  • Security Center
•Press "Scan".
•It will create a log (FSS.txt) in the same directory the tool is run.
•Please copy and paste the log to your reply.

This can show us if many items are missing / corrupted -

Thank You -
EDIT -
Go back and see Step 7 in the removal details. Now make sure all boxes are unchecked Except for, Automatically detect settings -

Hi

Thanks for quick response.

Re-read step 7 and you're right, there is a little bit missing from the guide...but the Automatically Detect Settings is (and was) the only box ticked.

Here is the FSS script - hope it helps.

Hi

Not sure if it's the right protocol to bump topics back up the forum listing after a few days?

Apologies if it's not (I do appreciate that everyone here volunteers their help)...just didn't want anyone thinking that I may have resolved this - it's still a problem!

Thanks

Rich

Can the laptop see the wireless network but not connect to it? Or does it not see the wireless network at all?

If it looks like I know what I'm doing, there's a pretty good chance the only reason for that is because
I once asked someone to run chkdsk /r and a BC Advisor smacked me in the back of the head.

Hi

Thanks for replying.

It can see the wireless network - just gives me a 'cannot connect' message when I try and establish a connection. Have tried deleting and resetting up, re-establishing connection by both the 'push button' and direct code entry...but no luck. Has really got me stumped....the laptop is only a few weeks old so am seriously considering getting the OEM discs out and just reinstalling.
