Nitro Update makes Avast light weight, low on system impact and improves system performance on Windows 10. Avast has released Nitro Update -a major one – to its flagship products and is available for download all Avast users such as Free antivirus, Antivirus, Internet Security and Premium.
Avast has streamlined their product by removing unnecessary hardware virtualization (NG) -which always runs in the background and consumes more system resources-and replaced with new CyberCapture technology that sends unrecognized and unique files to cloud for analysis, and re-sends the result, i.e either ‘dangerous’ or ‘safe’ to client after further checks.
