Restore files and system settings after a virus or malware

When using a Windows PC, it can happen to run into various problems, from the disappearance of the icons to the inability to launch some programs to the unavailability of some control or verification tools.
When there are errors of this type, the causes may have been:
- a virus which, even if removed, has nevertheless modified some settings or hidden some tools;
- an error of the user who, by mistake or ignorance, has deleted some files or has played imprudently with the registry keys or advanced system settings;
- a poorly designed program of those that promise to "optimize the system", instead ruining the stability of the system.
In any case, without going crazy looking for errors, there are some automatic repair tools developed specifically to restore the functions of a Windows computer after a virus attack .

Even if these are programs that are not very nice to look at and not too easy to understand even for those who are more experienced, they are automatic, so it is all about trusting or not.
Without taking responsibility for serious problems caused by misuse of these tools, I can give my "certification" on their goodness and on the fact that they actually work to repair the functions of the computer and Windows in case there are problems.
The best developers at making virus removal programs collect every program on the Bleeping Computer site, the best one where to find reliable programs for the cure of Windows when it shows problems or errors of various kinds.
Some Bleeping Computer tools such as rKill (tool to close the processes started by a malware mentioned in all the malware removal guides) are absolutely to be kept in the drawer because they are unique and life-saving.
From Bleeping computer you can download other tools such as, for example:
- Unhide: to return Windows icons if they disappeared from the desktop.
- FixExec if you are unable to run multiple EXE files or BAT files and, therefore, you can no longer open programs on Windows.
- MiniToolBox to restore all network functions in case of connectivity problems.
Among the various recommended programs is also Windows Repair All in one, a free Tweaking.com software to repair and solve problems of a Windows PC .
The program is all in English but still remains the best of its kind.
Upon opening, you can follow the 4 preliminary steps to follow before making system repairs .
In particular, it is said to:
1) Scan with Malwarebytes Anti-malware to make sure there are no viruses on your computer.
2) Do the scandisk to check errors on the disk: from Windows Repair to card 2 of the check disk, press the Do iT key.
3) Restoring Windows system files .
In the case of Windows XP it is necessary to insert the installation CD in the drive before pressing the Do it button, while for Vista Windows 7 and 8 it is not necessary.
4) Create a restore point and backup the registry before making repairs.
This is important because, if after using Windows Repair the problems were not solved and, indeed, there were new ones (you cannot guarantee that everything works magically), you can restore Windows as it was before.
5) Start Repairs tab, press the Start button to begin repairs.

At this point Windows Repair shows all the interventions it is ready to do which, roughly speaking, are all function restorations and corrections of parts of the system that could be corrupt.

Without making the complete list, Windows Repair is capable of :

Restart the computer and everything should be solved, unless the problems were of a different nature.
Windows Repair is perhaps the most complete suite of tools to restore Windows functions, which works with Windows 7, Windows 8, XP and other versions.
In other articles I had already listed some tools for computer repairs, among which it is important Microsoft Safety Scanner that checks the PC when the computer starts.
In the guide to restore Task Manager, Registry, dos prompt and other Windows functions after a virus or malware another program called Quick Disaster Recovery was indicated that I still feel like confirming today.
