Currently, a large package of anti-virus software is available for computers equipped with Windows, as many companies launch free versions of their paid anti-virus software, or offer their programs to companies that produce computers to be installed on devices in advance.

The Federal Information Technology Security Office of Germany indicated that the great threat situation justifies the abundance of offers from anti-virus programs, as new attacks are always monitored targeting Windows computers, in addition to the ever-increasing severity of malicious software, such as data encryption viruses and ransom demand, so there is no alternative To protect computers well.

The free defender antivirus program integrated with Microsoft Windows 10 system was seen as insufficient for a long time, but Microsoft has developed this program a lot recently and now it provides a secure protection on an ongoing basis, according to periodic tests The German IT security institute "IF-Test".

In these tests, Defender achieves very good results, or even better results, regarding the detection of malware and the dangerous "zero-day" attacks, that is, attacks that exploit vulnerabilities on the day they are discovered.

Here, the same question arises: Does Microsoft return other unnecessary programs? In response, Ronald Eckenberg of the German computer magazine "CT" explains, explaining, "In fact, other programs do not provide more protection, as free versions of antivirus programs are similar among themselves, and provide the same high level of protection."

Personal support
But the German expert pointed out that there are advantages offered by competing programs, as many companies provide personal support that Microsoft does not provide, and this feature is very useful for users with little experience. Such a service is available in premium paid versions of antivirus software.

In addition, these versions include many other tools such as safe file deletion or hard drive cleaning of unnecessary data. The need to purchase these gadgets is related to the user's personal needs. If the user has been relying on antivirus software for years, he will not need to replace his usual program with "Defender" if there is no reason for that.

What about ads?
The situation is completely different when it comes to ads, as many free anti-virus programs disturb the user by showing ads on the desktop, and pop-ups appear in the paid versions, which refer to other products of the same company. Fortunately, Defender gets rid of such ads.

An important rule applies to "Defender", as it must be always up-to-date similar to other antivirus programs. The program has been set from the factory to check for updates and install them automatically. It is best that the user does not interfere with the modification of these settings to ensure safe and comfortable operation. However, Microsoft cannot guarantee full protection from viruses like other antivirus programs.

German technology expert David Booth pointed out that the guarantee of virus protection is linked to the user's behavior, stressing the need to install new updates immediately. This applies in particular to the web browser, the operating system and all other programs that connect to the Internet, in addition to the need to install programs from known and trusted sources only, and not to click on suspicious links that often contain malicious software and codes.
