COMPUTER VIRUSES AND ANTIVIRUSES : AN INSIGHT



TYPES OF INFECTANTS:

VIRUSES: Small piece of software that piggybacks on real programs
WORMS: Computer program that copies itself from machine to machine
E-MAIL VIRUSES :Moves around in e-mail messages
TROJAN HORSES: Claims to do one thing, but does something else

VIRUS: WORKING PHASES

INFECTION PHASE: The file is infected
ATTACK PHASE: The infected file is run, and virus shows its action

Are Soil Pollution Risks Established by Governments the Same as
Actual Risks



1. Introduction
There is an increasing use of risk-oriented policies to deal with the local effects of soil
pollution. The risks that such policies deal with are: human health risks and can also
include ecotoxicological risks. These risks are expressed in terms of negative effects and
chances between 0 and 1 that such negative effects will occur

Risks related to one soil pollutant
In prac ....etc

Abstract We explore two different threading approaches on a graphics processing unit (GPU) exploiting two different characteristics of the current GPU architecture. The fat thread approach tries to minimize data access time by relying on shared memory and registers potentially sacrificing parallelism. The thin thread approach maximizes parallelism and tries to hide access latencies. We apply these two approaches to the parallel stochastic simulation of chemical reaction systems using the stochastic simulation algorithm (SSA) by Gillespie . ....etc

A large interest in renewable energy systems has been developed to mitigate the green house effect. In Western Europe, the focus is thus, on wind power and especially on offshore locations, due to higher energy production, a longer expected life time and lack of suitable wind turbine sites on land. A DC cable is the preferred choice when connecting large offshore wind farms to the grid. The utilization of the Dc cables was enabled by the new HVDC transmission technology using voltage sourced converters. The offshore windfarms that are being bui ....etc

A computer virus is a specially developed program that can copy itself and infect the computer system and harms your files in the system without the permission of Administrator. Now a days most commonly the term virus is used to refer to other types of malware, adware, and spyware programs that do not have the reproductive ability. Virus will be spread from one computer to another we transfer files via CD, DVD, USB etc. Virus will affect the performance of the computer system and slows down the PC to great extent.
You v ....etc

Viruses Work ( Download Full Seminar Report )

A computer virus is a self-replicating program containing code that explicitly copies itself and that can infect other programs by modifying them or their environment such that a call to an infected program implies a call to a possibly evolved copy of the virus. These software pranks are very serious; they are spreading faster than they are being stopped, and even the least harmful of viruses could be life-threatening. For example, in the context of a hospital life- ....etc

WINNERS VERSUS LOSERS

The Winner is always part of the answer;
The Loser is always part of the problem.

The Winner always has a program;
The Loser always has an excuse.

The Winner says, Let me do it for you;
The Loser says, That is not my job.

The Winner sees an answer for every problem;
The Loser sees a problem for every answer.

The Winner says, It may be difficult but it is possible;
The Loser says, It may be possible but it is too difficult.

When a Winner makes a mistake, he s ....etc

Computer viruses are mysterious and grab our attention. On the one hand, viruses show us how vulnerable we are. A properly engineered virus can have an amazing effect on the worldwide Internet. On the other hand, they show how sophisticated and interconnected human beings have become. ....etc
