Virus, Spyware, Trojan, Worm, Malware
These terms are often confused, although they have distinct meanings.
A virus is a piece of software that can copy itself and which attaches itself to some other program in order to survive and replicate. It may have some malicious intent or it may exist simply to reproduce. A worm is similar but it can exist independently; it doesn’t need to attach to a separate program. A Trojan – or Trojan Horse – is a piece of software that gains access to a computer by pretending to be benign or by hiding within some innocent-looking application. The name is obviously derived from the wooden horse employed by the Greek army during the Trojan Wars. Spyware is software that secretly monitors computer activity, attempting to gain private information without the computer user knowing.
By and large, all of the above will have some malicious intent – to harm data, spy on computer activity and so forth. Malware is a general term for all such programs – it simply means any software, of whatever sort, written with a malicious intent. Viruses are generally malware but there is more to malware than just viruses.

The co-operative banking industry in India plays a very important role in uplifting the economically weaker section of society. Initially started with the aim of helping the poor by providing financial help at a minimal rate of interest, co-operative banks are regulated by the Reserve Bank of India. Over the years, co-operative banks have been facing some tough challenges, but have managed to stay afloat, firmly.
