Antivirus & Ransomware
Antivirus & Ransomware
Antivirus software helps prevent, detect, and remove malware. Ransomware is a type of malware that locks your device or encrypts your files and demands payment to restore access.
Ransomware often spreads through phishing emails, suspicious downloads, or software vulnerabilities. Once infected, you may see a ransom message, lose access to accounts, or notice unusual activity on your device.
Warning signs include:
- Locked files or accounts
- Unknown programs installed
- Strange pop-ups or system behavior
- Unexpected financial or account activity
Staying alert, avoiding suspicious links, and keeping software updated are key to protecting your data and accounts.
Ransomware Questions & Answers
-
Toggle ItemWhy is it important to avoid Ransomware?
1. Financial Loss: Paying the ransom can be expensive, and there is no guarantee that the attackers will provide the decryption key or that the key will work. Additionally, the costs associated with downtime, lost data, and recovery efforts can be substantial.
2. Data Loss: In many cases, even if the ransom is paid, some or all of the data may remain encrypted or be permanently lost. The loss of critical data can be devastating for individuals.
3. Reputation Damage: A ransomware attack can damage digital reputations, especially if personal or sensitive information is leaked.
4. Operational Disruption: Students studies and daily activities can be significantly disrupted if access to devices or important files is lost.
5. Personal Data Theft: Ransomware can compromise personal information, such as passwords, financial details, and private messages, leading the identify theft and other cybercrimes.

Toggle ItemHow do I protect myself from Ransomware?
1. Backup Your Data: Regularly back up important data and store it offline or in a secure cloud service. This ensures that you can restore your data without paying the ransom.
2. Update Software: Keep your operating system, antivirus software, and all applications up to date to protect against vulnerabilities that ransomware can exploit.
3. Be Cautious With Emails: Be wary of emails from unknown senders, especially those with attachments or links. Phishing emails are a common way for ransomware to spread.
4. Use Strong Security Measures: Install antivirus software, enable firewalls, and use strong, unique passwords to enhance your device's security.
5. Stay Informed: Educate yourself about the latest cybersecurity threats and best practices to stay one step ahead of cybercriminals.

Toggle ItemHow else do I keep malware off my device?
There are several methods to prevent malware from entering your system:
1. Educate yourself on how malware works (good job, you're already doing that!)
2. Don't click on unfamiliar links. If you aren't sure where the link came from or where it goes, it's not worth the risk. One good practice is to hover over the link to see its URL appear in the bottom right corner of your browser. If it goes somewhere unexpected, it's probably malware.
3. Read emails carefully if they come from an unfamiliar sender. Spelling and grammar errors can reveal a hacker trying to trick you. See our phishing page for more information.
4. Don't visit sites that offer free access to things you should be paying for. It is always a gamble whether the files you are accessing are clean. This includes file-sharing sites.
5. Don't give out personal information to anyone without verifying how it will be used and by whom. Make sure people are who they say they are.
6. Don't give remote access to your computer to strangers.
