Uninstall the codec ? or System restore to before you installed the codec

Or install something like k-lite mega codec pack, it performs a scan and repair of codecs at the end of the install

ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
When the scan completes, push
Push , and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.

Try the malware advise above, if that fails I would try a system restore
