How do I know if my computer is infected by Conficker?

Question

I just heard about the new virus program that's out there. Is there a way to find out if my computer has it or not?

Answer 1

Go to any anti virus site, i.e. McAfee and if you cannot see the page, you are probably infected. The Conficker virus prevents you from seeing an anti virus site.



Make sure you have the latest updates from Microsoft and a great anti-virus software. If you have done that, you are protected.

Answer 3

If your computer is infected with Conficker, it's very easy to find out. Because the worm blocks attempts to remove it, it prevents computers from visiting Web sites where patches and cleaning tools can be downloaded. Below is a list of some sites Conficker blocks. If you are unable to visit them, your computer may be infected.

Network Infection In order to ensure its propagation the malware attemps to connect to other machines as described below.





IP address generation:

It creates random IP addresses while it keeps the first three octets from its own address. Afterwards it tries to establish a connection with the created addresses.





Infection process:

It makes the compromised machine download the malware from the infected source computer.

The downloaded file is stored on the compromised machine as: .\RECYCLER\S-%number%\%random character string%.vmx
