I know there is a way to get the 30 day premium trial by just using a random email and then letting it run out and it’ll turn to Kaspersky free (or repeat to keep getting Kaspersky premium) but I forgot the method.
To my knowledge, Kaspersky no longer offer a 30-day trial with just an e-mail. It’s been replaced by a 30-day money-back guarantee, requiring a credit card.
Kaspersky Free or Security Cloud Free (depending on your region), are available for download in most countries.
Go to kaspersky.com , do not use a VPN, and let the website change to your local version. Scroll down, and at the very bottom of the page, click on Site Map. Under Free, click on Free Cloud Antivirus. There, you can download the free version applicable to your region.
