This virus hides from the operating system when the system checks the location where the virus resides, by forging results that would be anticipated from an uninfected system. The different kinds of virus, one of them known as fast-infector virus infects not only programs that are executed but also those that are merely accessed therefore running antiviral scanning software on a computer infected by such a virus can infect every program on the computer. Another kind called the slow-infector virus infects files only while they are modified, so ....etc

ABSTRACT

As the networks are growing larger, so is the amount of viruses that hit the loophole. A relatively new unknown virus is said to cause some damage before being identified and prevented by existing Antivirus Engines since conventional approach is a reactive solution. The need of the hour is a pro “ active solution to avoid this initial damage. It also addresses a distributed updating mechanism, which allows for greater flexibility in detecting the returning viruses.
So the underlying principle is to construct an AV Engin ....etc

ABSTRACT
Viruses: A virus is basically an executable file which is designed such
that first of all it should be able to infect documents, then it has to

also be able to avoid detection.
Computer viruses can be classified into several different types.
File or program viruses: They infect program files like files
with extensions like .EXE, .COM, .BIN, .DRV and .SYS. Some file viruses
just replicate whil ....etc
