Free (for personal use) antivirus software for the good old Windows XP – 2017 edition

Despite the fact that Windows 7 and Windows 10 are the most popular operating systems on the market, Windows XP is still installed on some computers, for a various number of reasons. A statistics about the Windows XP usage can be found in this article.

Today I’m going to list a few free (at least free for personal use) and lightweight antivirus software than can still run on Windows XP, without making it.


From my experience, the best antivirus for Windows XP is Avast, having a lot of features, including:

  • On access protection against viruses and malware
  • Heuristics engine to detect previously unknown threats
  • Silent mode which hides alerts during full-screen user activities
  • Easy installation wizard.


  • It requires yearly registration.
  • It suggests installing additional software

Comodo Antivirus Free provides virus protection and on-access file protection, includes a Game Mode that does not display any notifications, updates virus definitions in the background and has both 32 bit and 64 bit installers.


  • Performs some system modifications that you might want to disable
  • Initial updates take a while to complete
  • The installer kit is very large
  • In creates a sandboxed environment for untrusted apps, not permitting them to infect the system

AVG Free:

AVG free is yet another antivirus system that can run on older computers that use Windows XP. It provides file anti-virus, anti-malware and anti-rootkit protection, web protection, email client protection, can be used in silent mode, can be controlled via a web portal and does not ask for registration before usage.


  • It slows down the computer
  • It installs third-party software by default
  • It recommends the acquisition of paid features
  • The Zen interface may be annoying

Immunet Free:

Last but not least on this list is Immunet, yet another free antivirus still compatible with Windows XP running on older computers.

Main features:

  • It is very light
  • Provides cloud-based anti-virus, anti-malware and anti keylogger protection

Kaspersky, ESET and Avast have released Dharma ransomware decryptors

All the security firms fight together in order to create decryption keys for ransomware viruses. The folks from BleepingComputer have added the master keys for the Dharma ransomware (Crysis variant) on their website and soon after that, ESET, Avast and Kaspersky have added the keys to their decryptor tools.

Kaspersky integrated it into its Rakhni decryptor tool, ESET added the same keys into their ESET Crysis Decryptor tool, while Avast added it to Crysis ransomware decryptor.

This means that the users that got infected with this ransomware malware and got their files encrypted with the .dharma extension can now recover their files for free, without having to pay the ransom.

Decryption tools are also available on No More Ransom, a campaign site run by Europol, Dutch National Police, Intel and Kaspersky.

If you don’t know this yet, the ransomware malware is a type of virus that encrypts all the data on the infected computer and leaves an instruction file on the desktop, to offer the necesarry information to contact the hacker and pay for the decryption key in bitcoin.

It is hard to protect your computers against it because every person with a little computer skills can create its own ransomware virus and harm others.

Personally, I use Cyberfree Anti Ransomware and I have both a Zemana antimalware license, to keep my computer safe from such viruses.

2016′ best antivirus was Avira Antivirus Pro, while Kaspersky Virus Removal Tool is the best for cleaning infected computers

The folks from AV-Test have conducted a 12-month endurance test, involving 897 evaluations for each security software for Windows 10 and took a conclusion.

They performed their research on two different stages: installed virus removal tools on infected systems and evaluated the results and disabled the security software so that the systems can get infected and again, evaluated the results.

Four of the tested solutions were capable of eliminating all the malware samples: Avira Antivirus Pro, Kaspersky Internet Security 2016/2017, Malwarebytes Anti-Malware and Avast! Free Antivirus 2016. Avira Antivirus Pro has also managed to remove all the registry keys so it scored best in all the tests.

Bitdefender Internet Security 2016/2017, Symantec Norton Security and G Data Internet Security have provided good performance as well, but missed malware in a few cases.

Among the bootable antimalware/recovery software, Kaspersky Virus Removal Tool ruled them all and managed to remove all the malware samples, while the others failed.

The screenshots below are self explanatory.

2016' best antivirus was Avira Antivirus Pro, while Kaspersky Virus Removal Tool is the best for cleaning infected computers

Personally, I am a fan of Malwarebytes Anti Malware when it comes to cleaning up infected computers, but I also use AdwCleaner, Zemana and HitmanPro, hoping to remove all the leftovers that were not spotted by my first virus scan. My favorite free antivirus is Avast!, because it is lightweight and has a lot of features.


Avast created 3 new ransomware decryption tools

As you may know, the number of ransomware infections has increased a lot in the last six months, despite the fact that antivirus companies fight it. Last year, more than 200 new ransomware malware were discovered.

For example, Avast has released 14 decryption tool so far, in order to help users to recover their infected data for free. The latest 3 decryption tools created by Avast can decrypt the files infected by Jigsaw, HiddenTear and Philadelphia/Stampado.

Due to the fact that the ransomware gets updated frequently, the security firms need to update their decrypting tools as well.

For example, HiddenTear’s source code is hosted on GitHub and can be used and modified by everyone. It encrypts files under the extensions: .34xxx, .locked, .BUGSECCCC,.bloccato, .lock, .saeid, .unlockit, .Hollycrypt,.monstro, .lok, .razy, .mecpt, .μ•”ν˜Έν™”λ¨, .flyper, .kratos, .8lock8, .fucked,.CAZZO, .krypted, .doomed et cetera.

The antivirus companies fight side by side against this kind of threats, due to the fact that there is no tool to offer 100% safety. So far, decryption keys from Avast, AVG, Kaspersky, Emsisoft, McAfee, Trendmicro.
