Install the Microsoft patches (Optional):
Install critical and important Microsoft patches. You can see the latest bulletins issued by Microsoft from here or from the official website.

Some questions
1. In spite of making all these indications my PC is still slow, why is this?
If after Windows disinfection was unstable, it is recommended to repair the system with these indications. If it is still unstable, it may be that the slowness is not due to viruses, but to the applications that are loading when you start your PC. It is recommended to uninstall programs that use less or that are expired, or simply to prevent them from loading when turning on the PC with utilities such as Microsoft autoruns.
If in spite of this the system is still slow, it is likely that the virus has damaged some important file, for that it is recommended to format and install the system again.
2. Have I removed the virus from my PC but I get messages when I turn it on, will it still be infected?
Most viruses are added to the system registry “Regedit” (a path key), in the “System Startup Files” or in “Start” of the Start Menu to auto-run every time we turn on the computer . When these viruses are eliminated these additions could continue in the system showing possible error messages (without this means that the PC remains infected). What you can do is remove them manually for example with the Microsoft autoruns utility.
