Key features of Avast

The software scans a device for any vulnerabilities in the system. It reports outdated software and automatically sends suspicious files for analysis in the cloud (Cyber Capture).

Ransomware Shield works in two modes to stop cybercriminals from accessing and altering personal files, and even encrypting them for ransom.

It comes with the Hardened Mode. We recommend enabling this mode because it includes a safe and proactive method of blocking new malware, including 0-day threats that can bypass antivirus technologies.

Any device connected to the Internet can potentially be included in a botnet as long as it can be infected with malware. Avast has special modules to prevent joining a botnet. This makes a device resistant to spam, data and identity theft, ransomware distribution, fraud, and other potentially illegal activities.

Remediation Time (RT) Legend
The time expressed in seconds from the introduction of malware into the system by a browser, through the launch, to detection and resolution of a security incident. The Remediation Time may depend on the real activity of the malware, which may increase the time. Occurs only at the POST-Launch level.

Example indicators

We can completely automate security tests carried out. For instance, we are able to record events of blocking an attack by a specific technology implemented in a product. If a product reacts to a malicious modification of the system, this kind of information is saved in the Windows event log or the local logs of the protection solution. We can capture such modification using the Windows API. For example, the activity of moving a virus to quarantine or running malware in a sandbox will cause the reading of a relevant key from the Windows registry or executing an action by a process. Then, we can mark recorded indicators as a detected attack, a blocked network connection, or an infected file removal. Here are some example indicators:

 ESET Internet Security:

C:\ProgramData\ESET\ESET Security\Logs\virlog.datMalware was removed or cured
*AppData\Local\ESET\ESET Security\QuarantineMalware was quarantined
C:\ProgramData\ESET\ESET Security\epfwlog.datBlocking of traffic by a firewall
C:\ProgramData\ESET\ESET Security\Logs\urllog.datBlocking of malware on a website
