Might not be enough, since some viruses are using firmwares and other things to be made more difficult or impossible to remove properly, if you can remember the story about HDD firmware being infected. Rootkit have been existing for a long time now. Not to mention the intel management engine thing, wifi firmwares, etc. I believe in the conspiracy theory that computers are now built with low security in mind, to make it easier to compromise by 3 letter agencies, as long as those 3 letters agencies are holding supremacy in the cyber weapon warfare. This still enables a few rogue black hats to lockpick those vulnerabilities every once and then, until most of them are caught and neutralized (either sent to prison or forced to work for those agencies).
