Modem connects to the network...but no internet is forthcoming..

[Mendo]

...hello

 

I really hope someone can help, my other half managed to pickup a virus the other week, which has been removed (along with a whole load of spyware nonsense).

 

But since then she hasn't been able to get on the internet. Her broadband connection will connect, but if she tries to open a webpage she gets a DNS error.

 

I'm sure (as sure as a computer idiot can be) this is a really simple problem but it's driving me (and more importantly her) absolutely mad.

 

She uses Windows XP and Firefox and also IE, to no avail. Does somebody have the solution to this problem...?

 

If you need any further information I can provide it.

 

Many thanks in advance if you can help.

 

Mendo :)

Hi Mendo

 

What is the exact error message?

 

What Anti-virus software are you using?

 

I take it its Internet explorer 7.

Also Go to start and then Run and in the box type cmd and press enter. In the window that opens type ipconfig /all and press enter.(space between the g and /) If you can tell us what it says there or make a screen shot.

 

But do this first to make sure there is no more malware on the computer, please follow the following instructions:

 

Your computer could be infected with Malware.

 

• Malware is software designed to infiltrate or damage a computer system without the owner's informed consent.
  It is a combination of the words malicious and software.
  The expression is a general term used by computer professionals to mean a variety of forms of hostile, intrusive, or annoying software or program code.
  

• Required Cleanup Steps
  1. Disable the Spybot Search & Destroy TEA TIMER if enabled
     
  2. Run a Temporary file and cache cleaner (ATF)
     
  3. Run 2 Anti-Malware scanners
     
  4. Run an Online Anti-Virus / Anti-Malware Scanner
     
  5. Clear out old System Restore points
     
  6. If continued Malware type activity is present you may be asked to post a TrendMicro™ HijackThis™ Log file
     

The reason to run multiple scanners is to ensure that no single scanner is missing something.

The time it takes will vary depending on your system and your internet connection speed.

Typically the SUPERAntiSpyware and Malwarebytes scanners will take between 10 to 90 minutes.

The ESET online scan should take between 1 to 3 hours.

In most cases, these scans will suffice to clean and disinfect your computer.

Heavily infected systems or slower PCs can take much longer to scan and clean.
