When a virus enters the computer it infects it and alters the files, critical areas, memory functions and causes damage to computers. Everybody who has a computer needs to protect it, and one of the best ways to keep your personal data secure is by installing reliable antivirus software. Day by day, increasing number of cyber attacks are happening. Malware and phishing attacks aimed at stealing the user data. WannaCry, a ransomware attack, infected a significant number of computers and encrypted the files for a ransom. People often think that they will not be prone to hacking attempts and they do minimal to keep their computer secure. However, hackers attempt to cause malicious harm to vulnerable computer systems.
Antivirus software monitors file changes and checks the memory for definite virus activity patterns, thus keeping the computer data safe. When the antivirus detects any known or apprehensive activity or pattern, a warning is sent to the user about the subsequent action that will be performed. Computer hackers manipulate the computer and how it behaves. Hacking techniques include but are not restricted to virus, worms, ransomware, adware, Trojans, phishing, rootkits, and browser hijacks.
Here is how antivirus safeguards your personal information from hackers:
Detection Of Malware
Antivirus software does not just detect viruses. They also detect all kinds of malicious software like keyloggers, rootkits, ransomware, spyware, etc. Antivirus programs have a signature database or definitions file which contains the fingerprints of all the recognized malware. Each time you download or run a program, the antivirus program will scan it for a fingerprint. If the fingerprint matches with one in the database then the program will get flagged as malware. Heuristics is a more sophisticated method of detecting malware. Heuristics works on detecting common behavioral patterns followed by malware.
Prevents Identity Theft
In the recent times, there have been quite a few massive data breaches. Identity theft happens when a hacker accesses your personal information and uses it for blackmail, credit information, and financial gain. You can be a victim of identity theft through a virus infection or phishing email. Strong antivirus software prevents identity theft from happening and they also have an anti-phishing feature.
Protection From Spam And Phishing
Phishing scams involve sending mass emails with a link or attachment which seems to have originated from a reliable source. Spam emails are not only just annoying advertisements but they can also harm your computer and steal your data. Files containing malware Trojan horses may be hidden in email attachments. If you open these files, the hackers will steal or destroy your personal data. Security software help in filtering, detecting and blocking spam emails.
Detection And Removal Of Keyloggers
Keylogger is a type of malware which the hacker installs on your computer. When a keylogger is installed, it makes a record of everything that you type including your passwords, bank details, emails, chats, social security number, etc. Antivirus provides a strong defense against keyloggers and removes them if and when they are detected.
