Disseminated via infected floppy disks, the virus itself was harmless, but it spread to all disks attached to a system. It spread so quickly that most cybersecurity experts consider it the first large-scale computer virus outbreak in history. Another early problem was the Morris worm back in 1988, but that was a computer worm rather than a computer virus.
Early viruses like Elk Cloner were mostly designed as pranks. Their creators were in it for notoriety and bragging rights. However, by the early 1990s, adolescent mischief had evolved into harmful intent. PC users experienced an onslaught of viruses designed to destroy data, slow down system resources, and log keystrokes (also known as a keylogger). The need for countermeasures led to the development of the first antivirus software programs.

Those using antiviruses online had to regularly download an ever-growing database file consisting of hundreds of thousands of signatures. Even so, new viruses that got out ahead of database updates left a significant percentage of devices unprotected. The result was a constant race to keep up with the evolving landscape of threats as new viruses were created and released into the wild.
Some anti-malware products can also run the suspected malware in a sandbox, which is a controlled environment in which the security software can determine whether a program is safe to deploy or not. Running malware in a sandbox lets the anti-malware look at what the software does, the actions it performs, and whether it tries to hide itself or compromise your computer.
Two relatively new forms of malware have helped drive the advancement of signature-less detection methods: exploits and ransomware. Though these threats are similar to others in many ways, they can be much harder to detect. Furthermore, once your computer is infected, these threats can be almost impossible to remove.
Exploits get their name because they literally exploit vulnerabilities in a system, software, or web browser in order to install malicious code in a variety of ways. Anti-exploit measures were developed as a shield against this method of attack, protecting against Flash exploits and browser weaknesses, including new exploits that have not been identified or vulnerabilities for which patches have not yet been created.
Ransomware emerged on the malware scene to spectacular effect in 2013. Ransomware made a name for itself by hijacking and encrypting computer data, and then extorting payments as it held the data hostage. and even threatened to erase it if a deadline passed without payment. Originally, both these threats resulted in the development of dedicated anti-exploit and anti-ransomware products.
In December 2016, Malwarebytes folded anti-exploit and malicious website antivirus protection into the premium version of Malwarebytes for Windows. We have since added anti-ransomware for even more advanced anti-malware protection.
Put another way, AI focuses on building smart machines, while ML uses algorithms that allow the machines to learn from experience. Both these technologies are a perfect fit for cybersecurity, especially since the number and variety of threats coming in every day are too overwhelming for signature-based methods or other manual measures.
In the case of business IT professionals with multiple endpoints to secure, the heuristic approach is especially important. New malware threats emerge regularly, so heuristics play an important role in Malwarebytes Endpoint Protection, as does AI and ML. Together, they create multiple layers of antivirus protection that address all stages of the attack chain for both known and unknown threats.
Whether you use Android or iOS, mobile devices face online threats too. As mobile operating systems go, Android is more open in a number of ways than iOS, and so protection for each is different. Antivirus for Android, for instance, often includes some app scanning capability, as the Google Play Store tends to have much less stringent requirement for apps to make into the store than the iOS App Store. On iOS devices, scam websites can be a bigger concern than rogue apps, for instance. Malwarebytes offers protection for both Android and iOS:
Industry watchers have cited Malwarebytes for Windows for its role in a layered antivirus protection approach, providing one of the best antivirus programs without degrading system performance. It removes all traces of malware, blocks the latest threats, and is a fast virus scanner.

Hi all, i'm currently testing some features of our PA-500, i've activated the antivirus policies and going on eicar i can see it blocks the download of the file, when i try to download from https the download proceed. How i can check and block antivirus threat over https session?
1) Create a new CA (as a test this can be done with openssl) - set expiration for 10 years or so (if you set for example 1 year you would need to redo this work once a year so its up to any ceritifcation policies at your workplace which expiration times are allowed).
The last part is only to make this transparent for the clients - otherwise they will get an warning in their webbrowser that the cert used by the site the client is visiting isnt "trusted". Of course the client could just allow it anyway or for that matter install the cert to avoid get a warning next time - but PA will on the fly generate a new "MITM" cert next time the client visits the particular url.
A good way to test if your SSL-termination is setup correctly is to visit and download the eicar testfile from (both http and https options are available along with .exe and .txt): -0-Download.html (for more information: -0-Intended-use.html).
That is because the PA will on the fly generate a new "faked" (MITM - Man In The Middle) cert using this CA cert before sending the traffic to the client (who if point 4 above is done will not notice that its being inspected (unless the client manually inspect the cert received and will notice that the issuer is changed and that the fingerprint (compared to the original cert) doesnt match (if the visited site have published their fingerprints online or if the client some other way knows what the correct fingerprint is)).
Hi i have generated the certificate directly from Paloalto, the problem was that the name of certificate. We have ricreate the certificate with name the ip address of appliance and now it seem's to be working better. Now using the eicar download test, trying to download a file in http i see a blocked response web page, and in https it remain in working and remain in cycling. It doesn't display the response page but don't proceed to download of the file. Have you seen the same behavior ?
Visit the url in question and verify that your MITM-cert was being used (check the "issued by" stuff when you click on the cert on clientside - it should read the name you gave the cert (issuer) instead of Verisign or whatever the EICAR-site uses).
I have sometimes noticed that occationally the PA unit will let bad code pass, dunno why as I have not yet setup a testcase for this or even did a tcpdump so see what actually happens - the result was anyway that I got open the EICAR.txt over https instead of getting the blocked virus page.
One theory is that the PA unit will send the TCP-RST (or whatever) just after the first packet passes as with EICAR the EICAR teststring will fit in a single packet. Then based on which browser is being used the browser will try to display whatever it got instead of displaying the block (well antivirus) page generated by the PA.
For the app, i ve no problem in http or https, example facebook, facebook app or other, but for antivirus features when i try to download the eicar test file in http i see the block page, and in https i see the timeout as you. No news.
I have exactly the same problem. I have configured two ssl forwarding certs (a trusted and a unstrusted cert) and imported both certs into my browsers "Trusted Root Cert. Authorities". Configured the ssl decryption policy and tested a few ssl sites with valid and invalid (self signed) certs. All worked as expected except the Eicar tesfiles with ssl. I can see the block in the Threat log, but no response page being displayed in the browser, just sitting there until it times out. 152ee80cbc
