How to find this setting:
Main Console > PC/Mobile > PC & Internet Security > Virus & Spyware Controls > Scan Preferences
Your security software analyzes basic information about every file that you open, save, or download. For threats like viruses, it attempts to remove the threat from the infected file. If unable to remove the threat, it deletes the infected file along with the threat.
Select Scan for threats when opening, saving, or downloading files to detect and eliminate security threats automatically.
Important warnings appear when your security software deals with a threat.
Select Display a warning after detecting viruses, spyware, or suspicious behavior to make sure you see these messages.
Your security software can not only search for threats in files and settings, but also check for suspicious behavior on your computer.
|Check if programs try to make unauthorized changes to system settings that could threaten your security||Blocks suspicious changes to the computer. Such changes can result in web browser hijackings, unwanted but unremovable web browser toolbars, or reduced computer performance, among other problems.|
|Prevent programs on portable drives from launching automatically||Blocks programs that try to start running without your permission when you plug a USB drive into the computer. Flash memory or other portable USB drives rarely include certain kinds of programs that launch automatically, so they usually represent a threat if found.|
|Enable real-time scanning for compressed files (like ZIP files)||Checks files reduced in size through data compression techniques. Such files commonly end with the ZIP or RAR extension and require a specific program to "unpack," "unzip," or "decompress" the contents.|
|Automatically delete files that show any signs of a threat||Gets rid of any file that might cause trouble. This aggressive response could remove some harmless files along with the unsafe ones, so consider using this protection only when receiving files or installing programs that seem risky.|
