how to remove virus from my computer

 

Virus is a program that behaves in a manner similar to that of a biological virus. Once a computer has been infected with a virus, the virus can replicate and spread to other computers. Some viruses are capable of lying dormant for long periods before becoming active.

The term "virus" is also commonly, but erroneously, used to refer to other types of malware.

The majority of active malware threats are actually trojan horse programs or worms rather than computer viruses.

Many types of malware have the ability to replicate themselves, but they are not considered viruses because this replication occurs after "infection" at the instruction of the software, not as part of an self-perpetuating cycle as in a virus.

Since modern computers are usually not capable of executing code directly stored in memory, most viruses must infect other programs in order to spread.
