My IP configuration is lost, and it appears that a trojan has deleted my IP address, how can i stop this virus

When doing run-cmd and typing "ipconfig /renew", the text that comes up is "An error occurred while renewing interface Local Area Connection : An operation was attempted on something that is not a socket." I am unable to get access to the internet on that computer in any way, so i cannot download any programs to remove this virus. It was called rsvp322.dll previously and was in C:WINDOWS\system32 folder. I can no longer find this anymore on my computer after multiple searches, how can i fix this?

A computer virus is a small program that infects a computer without the user permission. It attaches itself to other files and quickly multiplies.


It is strongly recommended that you use an antivirus program on your computer and that you keep it updated. This will prevent any infection and clean your computer if it was infected previous to the install.





You are infected with a virus if:





* Your computer is very slow, stops responding, restarts or shuts down by itself from time to time.


* Your hard disk or the removable drives (floppy drive, CD-ROM, USB Flash) are inaccesibles or the files are corrupt.


* Unusual error messages appear.








In case your computer got infected, try the following:





* Get an antivirus program (if you don't have one already) See the Download antivirus page to get a free one.


* Update your antivirus


* Scan all your computer and delete, repair or quarantine the infected files.





If you have problems in eleminationg viruses from your computer, you can also try one of the free tools available in the Other download page.





To keep your computer virus free:





* Have an antivirus program and update it from time to time (some even update automatically)


* Use a firewall. Download one from Download firewall page.


* Only download files from sources you trust.


* Don't open e-mail attachments, unless you know who sent it.


* For more protection you can scan your computer with online scanners provided free by some of the best companies. See the Online scanners page.


* Spyware may sometimes be mistaken as a virus. Read about spyware.
