One Click Can Destroy a Whole Company: The Different Types of Malware
Imagine opening an innocent-looking email attachment… and suddenly your computer freezes, your passwords disappear, or all your files are locked. Sounds like a movie scene? Unfortunately, it happens every day through something called malware
Malware is any software designed to harm, damage, or secretly access your computer or data. Cybercriminals use it to steal information, spy on users, or even demand money.
Let’s talk about a few types of Malwares and how they disguise themselves
Viruses
It usually spreads through infected files, downloads, or email attachments. The scary part? A virus often cannot activate until you open or download the infected file. Once activated, it can corrupt files, slow down your computer, or spread to other devices.
Trojans
A Trojan is a nasty, sneaky type of malware that disguises itself as something harmless to fool you into installing it. Once installed, the Trojan can create backdoors for attackers, steal sensitive information, or install additional malware.
Ransomware
Ransomware is one of the most dangerous forms of malware. It encrypts a victim’s files or locks them out of their system and demands a ransom payment in exchange for restoring access. Businesses, schools, hospitals, and individuals have all fallen victim to ransomware attacks.
Worms
Unlike viruses, worms do not need a host file to spread. They can automatically replicate themselves and move across networks, infecting multiple computers within a short period. Worms often consume network bandwidth and system resources, causing computers and networks to slow down or crash.
