If you are experiencing “ File system on local disk C contains critical errors” warning message in your Windows system, then don't sweat because it is not real but a trick of a harmful and malicious Hard disk defragmentor tool called System repair. Actually, the warning is generated by this fake tool itself for users to scare them. In addition to this, the warning also suggests running System repair wizard to fix them. Just like a real tool, it will scan and claim to fix the error but on condition that you agree to buy the full version.

System repair through this website downloads more harmful things in addition to fetching your credit card credentials etc.
Hence, File system on local disk C contains critical errors is not real and should be ignored in the first place. In order to get rid of such fake alerts, uninstall System repair tool at the earliest.
