Help out please

Sometimes the anti- virus can mis identify a file, but it could be a legitimate virus. Are you able to update the anti virus? Are you able to put the file in a quarantine? What it may be telling you is that there is a virus disguised as a system file. Does it let windows start? Please give all the details.

Yes i m able to update my anti virus, and i m able to put files in quarantine. Yes it does let windows start...

Boot into safe mode with networking. Download, install, and update malwarebytes. Run a full system scan. If it's legitimate malware, it will confirm it, and you can remove it.

Are you able to scan the entire system with Guardian 2009?

Yes. And my antivirus is working perfectly alright

If it is working, then it should be able to update, scan and neutralize or quarantine the virus.
