This tutorial aims to give you the means to disinfect your computer in an autonomous way concerning the rather important infections (Trojan, backdoor etc).

This procedure is intended for computers with multiple infections and not for computers infected with adware (pop-up of unwanted advertisements), I advise you to refer to this procedure instead:  Remove adware and parasitic programs

If you have a "simple" infection or symptoms that are not necessarily synonymous with infections (crash, slowness), there is no point in following this procedure.

How to remove viruses

Disinfecting a system can damage it; the system may no longer start.

He is very deeply advised to back up your data in the event of a Windows crash during disinfection.
If this is not the case, burn your data or copy them to an external hard drive / USB keys (be careful of removable disk infections).

In case your system is crashed .. and you have not made a backup .. you can follow this tutorial: Recover your data and possibly post on the forum asking for help getting Windows back on track (in case it's possible).

The cleaning consists of going through the utilities one by one.
As far as possible and for better efficiency, you should follow this procedure without interruption, ie avoid restarting in normal mode.
Do not hesitate to leave the scan running overnight if it takes a long time.

NOTE: if the Malwarebyte or Combofix programs do not start (nothing happens when you double-click on them), rename the files to winlogon or explorer.

Some infections block these programs in order to prevent disinfection. Example Total Security or some variants of braviax

After that ?

The majority of infections today incorporate keyloggers or run programs that search for passwords for your WEB sites.
It is strongly recommended to change the passwords of ALL your WEB / FTP sites, especially if you are viewing your bank, eBay, Paypal, etc.

The question that comes up most often after an infection is "what is the best antivirus" - "Are my protections good?" ".
Are you looking for the ultimate antivirus that helps protect your system?
If so, you are not asking yourself the right questions ... Infections do not happen on their own and are either the result of bad habits or a lack of knowledge of the computer tool that malware authors take advantage of.
To overcome this, it is necessary ...... to read and document yourself a minimum.
