- Clean install
Even if fully system scan can find and fix threats, you should do a Clean install as they may have made unrestorable changes to your system.
Please make sure that you have backed up all your data before performing a clean install.Disclaimer: At this point, we have exhausted all troubleshooting and I recommend that we try to perform a clean install to get your computer back into a working condition.
