Is Linux virus free?

It is a common question that why  we use an Anti-virus in Windows while it is not a must in Linux. The answer is not that viruses don’t attack linux. The crackers are more interested in causing major destruction and harm for large number of users and they prefer Windows as it is most commonly used. Also Windows is not open source. The Open Source Community where Linux belongs to is Ultra fast at fixing the virus, spyware problems compared to Microsoft because Microsoft is slow to respond. There are Antivirus softwares available for Linux too. Some of them are Avast, Bitdefender, ClamAV and AVG. These might not be needed at the moment. But as linux gains in popularity, crackers will turn towards linux too with their evil intentions. Linux doesn’t suffer from most of the viruses but there are still large batches of software that “infect” Linux machines. Rootkit is one of the malicious program to get into a linux machine. Rootkits allow someone to gain top-level system access and control while not alerting the actual users of the system that anything has changed. These rootkits can modify and spy on data or run programs in the background without any of the processes or data accesses appearing to the legitimate users. The fact that another user logged into or is still logged into the machine could also be completely hidden. Other kinds of malicious software and data that can find its way on Linux machines are loggers, poisoned DNS entries, backdoor botnets, harvesters, spam gateways, etc. Anways, compared to the 50,000+ Buerocratic community, the open-source community is huge and Linux can offer a secure platform for the users and hence fix its domination.
