I failed an exam some years ago over that exact question. I said yes, every virus could be reverse engineered with a definition file and it was marked wrong. It seems that sometimes they antivirus folks cant figure out exactly how the virus works, but will figure out how to disable and remove it. Then they just incorporate this into their av and move onto the next virus. Somebody with a background in programming would have a far better idea about this and could explain in alot more detail than I can.
Yes and no. No because an anti virus and yes because a lot of virus definitions are reported in virus killers before the virus is made. So in short no it's a Antivirus that probably make their own virus's.
An antivirus database? I have heard them called definitions instead of signatures, and they are loaded into an antivirus program in order to scan your computer.
Each antivirus uses up about 5% of your ram when it is not running. if you install more than one anti virus your computer will become extremely slow
Antivirus software can prevent most, but not all virus infections on a computer. This is because antivirus programs have one major disadvantage: they detect viruses using a large database of the signatures of every known virus. Because new viruses come out daily or even hourly, antivirus companies are falling behind malware writers. One report stated that the Symantec antivirus company had to create 36 new signatures every 7 seconds in order to keep up with malware writers.
Virus is also called as tracking of virus, nothing but providing antivirus program to set your PC free from viruses.
Almost all antivirus programs will provide virus alert. Some popular programs are Norton Antivirus, McAfee, AVG, Bull Guard, Panda Security, and Avast.
Updated virus definitions are downloaded
It will work, but the virus definitions will be out of date, so any virus made after 2006 CAN infect you.
Removing a virus from your PC can be a tricky ordeal, but with a little patience, time and understanding, you can work like the pro's and remove it yourself. For a complete e-book, try orioncsi.com. There are some terms and concepts you should be familiar with, starting with running a computer in safe mode. Safe mode bypasses normal windows settings, user settings and startup programs from running. Once you are able to boot your machine in safe mode, you want to start up your antivirus program and try updating its definitions. A sure sign a virus or malware is dug deep into your system is you will not be able to update your antivirus program. If the problem is not too severe, you will be able to update your antivirus programs definitions and run a scan to remove what ails the machine. If you are not able to update the antivirus definitions, there is an inexspensive step-by-step guide to virus hunting with the Orion CSI product.
No, but most antivirus programs will mistake it for a virus because of how it works.
Antivirus programs
Yes and no. No because an anti virus and yes because a lot of virus definitions are reported in virus killers before the virus is made. So in short no it's a Antivirus that probably make their own virus's.
Antivirus is a program that detects, prevents, and takes action to remove viruses, worms and Trojans.The antivirus programs such as AVG,Avast or immunet detects and remove the virus.
Yes. You can download antivirus software (there are free ones can do it), update the virus definitions, scan your computer with it, and delete/remove it or quarantine it.
If you are interested in the last update for Norton Antivirus, the best place to look in on the actual website. Not only can you get newest virus definitions but also keep up on the latest developments in virus protection.
A bug is a insect and an anti virus programs that wont send no viruses in it.
Personally, I use Avast Antivirus and recently upgraded to a two-year subscription of their Internet Security program. Speaking from experience with Avast and computers, no antivirus software can delete every virus made at any given moment. Virus definitions (how antivirus programs identify viruses) are updated daily even through the free version of Avast. So viruses can eventually be deleted or as Avast refers to as "quarantined," but needless to say is very effective and highly recommended. See the related links below to download it.
