How many viruses are there on the internet

A good starting place is here:. First are some great, safe security programs that not only protect your computer, but also allow you to run some other programs like a Free Space cleaner and such:. They are both free, another program that requires subscription and payment is Norton Internet Security.

If you run back-to-back scans with these programs everyday and keep them updated your computer will remain safe and secure. You might want to check out the facts about Macs and viruses….

Virus writers in the past were motivated by how far their virus can spread. With the Windows installed base that still makes Windows the larger target. Mac after OS X: 0 viruses. PC: more than 10, viruses. Then what are the real numbers?

Please read the article. Numbers are not important and vary depending who you ask and how they counted the many variants of malware out there. There have been more and Apple even admits that because it has a scanner of sorts built into the OS and updates the list of things looked for on a semi-regular basis.

How many exactly? Each changes different things and installs in different ways. Of course you could always just reformat the disk and reinstall Windows and all programs and data from scratch or backups made before the virus attack.

That, at least, would guarantee a clean system. An image backup would also serve the purpose you ask about. If you check with the leading security companies, you might be tempted to pick an answer in the millions. Oh my. That certainly sounds like a very big number.

Definition files are a great way of assessing the degree of activity at a computer security company. They vaguely measure the current intensity level of the cat-and-mouse game between malware authors and security companies. I took a closer look at the Symantec definitions for that week and found a very interesting story.

On any given day, it displays the total number of new and revised detections, followed by their details, like this:. The total number of named entries listed in the summary of those definition files during that period was —12 new and revised. It appears to be a count of individual pieces of identifying data—signatures—associated with those named entries. That list includes a lot more than malicious software, too. When I excluded those categories, I ended up with only named entries in the Trojan, Worm, and Virus categories.

I was surprised to find that many of the definitions on this list are for very old pieces of code. During this one-week period in April , Symantec updated its definitions for the following pieces of ancient malware and bumped up the counter in its definition files accordingly:. In addition, these April definition files include multiple revised detections for Waledac and Rustock, the Trojans responsible for two prolific spam botnets that were decisively shut down in February and March , respectively.

For each named entry, Symantec includes the date when that entry was first added to its definitions list. Only 31 entries were discovered in or Here, we illustrate how you can recognize nine common computer viruses. Computer Virus Statistics. Ransomware Attacks and Data Recovery. Costs of Cyberattacks.
