II. Types of Computer Viruses

Viruses encompass a wide range of malicious software (malware) performing different disruptive or illegal activities once launched on target systems. Common virus classifications include:

Viruses – Self-replicating malware spreading between files and systems by inserting code into benign applications or documents. Traditional viruses distribute via downloads and external storage devices.

Trojans – Malware masking as legitimate applications to dupe users into installing them for backdoor access. Allows remote execution of code, information theft and additional malware downloads.

Spyware – Software capturing personal data like web browsing habits, login credentials and financial information without consent. Often piggybacks other software installs or downloads from questionable sites.

Ransomware – Malware encrypting documents, media files, entire drives and even connected systems to extort owners into paying ransoms, usually in cryptocurrency. Proliferating through infected email attachments and malicious ads.

Identifying virus strains using reputable malware databases helps free removal tools leverage the optimal detection signatures, quarantine methods and cleaning procedures.
