CT: Reactive scanning is the bread and butter of an antivirus. Basically, it scans any new program or file before it’s opened and checks if it is a known malware or if it behaves like one.
It’s all done in the background, and the scanned file or program only opens once the antivirus has finished the scan.
Then there is the full system scan, where the antivirus goes through every nook and cranny of your device in order to find malware or any other suspicious software or files.
Some AVs also block malicious ActiveX or Java scripts from infecting your PC. Plugins based on these technologies can be used to make your PC part of a botnet, inject code or do drive-by downloads.
