Develop Defensive Habits
- Scan for virus from external storage: flash drives, hard disks
- Scan for virus/spyware at least weekly
- If some program prompts you to install, don’t if you are suspicious. However, some ActiveX from trusted websites such as microsoft.com can be safe
- Don’t open attachments from someone you don’t know. Scammers and virus spreaders can even fake their email address to something familiar to you, so just don’t.
- Don’t visit sites that look suspicious
- Check your browser’s status bar left corner (the bar at the bottom of the window) for the URL while hovering your mouse over the link
- If the domain name is from a source you know well, it is safe. Example of domain name: taitran.com is this site’s domain name
- If the URL is hidden then it is suspicious
- If the URL contains commercial words such as “refer”, “bill”, “cash” in its domain name then it is suspicious
- If a message sent to you via Instant Messages contains links and a message that looks like mass-sending and is ambiguous (come here and check), it may be auto-generated by a virus. It also applies for IM statuses
- The recent virus spreading in Vietnam is Vietnamese without accent. We can assume that messages with accent might be safer, but this is not guaranteed.
- Confirm with the sender if they sent suspicious-looking messages. If they don’t know, the message contains virus.
- Resist temptation (!) to click on tempting links
How to send messages that contain safe links to people who have already been cautious
- Sign your message with your name
- Address the receiver by name or group name (dear RMIT alumni)
- Write in Vietnamese with accent
