Concept of Malware
You can get completely mad trying to understand which antivirus product to choose if you read countless reviews and tests. Results often contradict one another even coming from independent sources. Let’s try to understand why it is happening and what measures of common sense we could apply to protect ourselves from viruses and from lousy security products.
Concept of Malware in 2009
The public misconception of viruses makes people think that if nothing suspicious happens, they are fine (the opposite of that can be very exhausting, to the extreme when after any noticeable slowdown people blame a virus and reinstall the system from scratch!). A modern virus is far different from a virus 10-15 years ago. It used to be done for fun—deleting files, making computer unusable, irritating user with offensive messaged, and so on. Infection in most cases was obvious and virus creators were like warriors of the underground world, looking for fame and glory. Not anymore. Malware writing is a big business now. That big business wants to be in the shadow, because it is mostly criminal. Infected computers connected to the internet are organized in botnets. Number of bots (remotely controlled workstations) connected can be up to few hundred thousands (!), commanded by only one masterbot. That power can be used to generate spam, DOS attacks (“denial of service” when massive number of requests can completely disrupt a web-server (website) operation), brute-force cracking, illegal/secret information exchange and storage, fake ad hits generation and so on. Botnets are available for rent in the underground.
