Hi there,

We recently had an ADSL line installed in our apartment and I've been able to connect and work away, issue free, on my own laptop. The problem is with my girlfriend's laptop. I can connect to the internet through IE, but if I try to browse through Firefox, I get an "Unable to connect" error, e.g. Firefox can't establish a connection to the server at www.google.com. A similar problem occurs with applications that require internet connectivity, such as Windows Automatic Updates and antivirus software - they experience connection errors when trying to update.

I've been on a couple of other tech support forums to try and find a resolution but nothing has come of them yet. Various responses have suggested that there is malware on the laptop preventing the connection and one poster recommended this site, so here I am. What we have already established is that the issue is with this laptop. There are no problems with the router or the connection between the laptop and the router. I don't really want to go over old ground again so please just accept that this is how it is!!

What I have already tried:
- Turning off firewall = unsuccessful
- Internet options = OK
- IP address, Default Gateway, DHCP and DNS servers = OK

I have the latest version of AVG antivirus running on the laptop.
Spyware and malware apps which have already scanned the system include:
- Spybot Search & Destroy
- MalwareByte's Anti-Malware
- TDSSKiller
- ComboFix

To my unprofessional eyes, the laptop looks squeaky clean and any virus, spyware or malware (of which there was very little in the first place) seems to have been cleared out. I really don't know what else to try so it's over to you guys n gals.

Thanks
Niall

Since you ran Combofix, Please follow the instructions in ==>Malware Removal and Log Section Preparation Guide<==.

Once the proper logs are created, then make a NEW TOPIC and post it ==>HERE<== Please include the link to this topic in your new topic and a description of your computer issues and what you have done to resolve them.

If you can produce at least some of the logs, then please create the new topic and explain what happens when you try to create the log(s) that you couldn't get. If you cannot produce any of the logs, then still post the topic and explain that you followed the Prep. Guide, were unable to create the logs, and describe what happens when you try to create the logs.

Once you have created the new topic, please reply back here with a link to the new topic.

Most importantly please be patient till you get a reply to your topic.
