Avast Antivirus

The first virus and malware protection program we recommend using on Windows 10 is Avast . It is a very well-known software on the market, especially because it offers a truly effective free solution called Free Antivirus . The program is able to completely protect the operating system and constantly monitor all the activities carried out. To download the free version you just log on to ‘ special Web page of Avast and press the button Download free . Alternatively, 3 other versions are available: Internet Security ,Premier and Ultimate . Through the dedicated page , you can find out the differences between these 3 editions of the antivirus software.

Kaspersky Internet Security

The Russian software house, one of the most renowned in circulation, has created an antivirus for Windows 11 to definitely keep among the first options if you want to stay protected. Compared to Avast, which is perhaps the most complete suite,  Kaspersky Internet Security certainly has fewer options, but its scanning engine is among the  best around . By purchasing the Premium version, ” Real-time protection “, ” App lock “, ” Anti-Phishing “, ” Internet protection “, ” Privacy protection ” will be unlocked“, Interesting options but that other software allow, at least in part, for free. Power, lightness and ease of use are not a preconception but simply reality, as demonstrated by the AV-Test tests that reward Kaspersky Mobile Antivirus with  flying colors in all categories .

AVG Antivirus

Which antivirus to choose for Windows 10 ? Another great antivirus you can install on your computer is AVG . The program manages to guarantee pretty good performances since it can count on an excellent virus scanning system that is completely free. The only problem is that the free version occasionally shows pop-ups of various kinds that might disturb you. So, to download AVG AntiVirus FREE , simply log on to ‘ special Web page and press the button Download to HTML.it . Alternatively, you can opt for the Internet Security or Ultimate version which would be the most advanced solution for antivirus protection and PC optimization.


The well-known Slovak company has launched (like almost all known antiviral software houses) in the Android world with its Antivirus Mobile Security. In its free version,  Eset NOD32  allows you to protect your device from  viruses  and  malware,  to carry out automatic  and  manual checks  ,  and features an anti-phishing filter  . Although it has been my personal choice for over a year, for AV-Test it is not the best, in fact in the evaluation for protection it gets an excellent, but lower than the others, 5 5 out of 6, although in usability (and I would add in lightness) it is a  cut above the others .

Another highly recommended antivirus for Windows 10 is Avira . In fact, we are dealing with antivirus software that offers a much higher level of protection than the competition. Also, just like AVG and Avast, there is a free version called Avira Free Antivirus . To proceed with the download of the 2019 release, connect to the dedicated web page and press the Free Download button . Alternatively, you can take advantage of additional features (e.g. protection from evolving ransomware threats, scanning email attachments, downloads and USB devices for malware, unlimited customer service, and so on) by opting forAvira Antivirus Pro .

Bitdefender Internet Security
