No. Antivirus companies know the risks involved when dealing with computer viruses and the potential dangers of viruses getting out in the wild. The whole concept of antivirus companies creating viruses is a myth, urban legend, and a conspiracy theory.
How does antivirus software identify potential viruses?
Antivirus software compares the signatures of the files on your system to the virus signatures in the signature database to see if any signatures match. If they do, a virus has been detected. This method works well for detecting known malware.
What are the steps to update the virus definition of antivirus software?
