If you're going to use antivirus software, you may want to choose something other than Kaspersky. While Leo believes Eugene Kaspersky, the CEO of Kaspersky Lab, is a great person, his company is Russian and may be prone to manipulation or seizure by the Russian government/military. In any case, Leo simply recommends excellent alternatives with less baggage. While we don't know for sure what goes on with companies like Kaspersky or Huawei, it's best to err on the side of caution.
Robert is wondering if he needs to get an Antivirus for his smartphone. Leo says it would be unnecessary since the phones' Operating Systems are already quite secure thanks to Apple and Google's efforts. An Android device, for example, will scan apps downloaded from the Play Store (which is the best a 3rd-party app can do anyway).
Mark wants to know if it's safe to use Kaspersky antivirus software. Leo says that Kaspersky is a great AVS utility, but it has fallen under a cloud of concern because the Russians may have used the software as a spying tool. The US Gov't has banned the use of it as a result. So it's probably best to err on the side of caution and avoid it.
If you need an AVS, Leo recommends using Windows Defender. It's free and comes with Windows 10.
Kevin has an old laptop and wants to know if he needs Webroot antivirus. Leo says that back in the day, Webroot was very good. But lately, If he's able to update to Windows 10, Windows has its own antivirus called Windows Defender which is very good. Before Windows 10, Microsoft had Windows Security Essentials. Both are essentially the same, and they're free.
Chris wants to know if he really needs Webroot and Windows Defender. Leo says he doesn't need Webroot at all, and it's likely they paid the computer company to put it on. He should free to uninstall it. Windows Defender will do a great job and it comes free with Windows 10.
Bob has noticed that Leo hasn't been advocating for antivirus software lately, and his subscription is expiring. Should he renew it? Leo says that most malware hacks are Zero Day now, and security programs aren't really effective against them. Antivirus software even can cause problems. In general, antivirus software isn't really worth subscribing to. Windows Defender is free and offers protection that is perfectly fine. The best defense is his online behavior, and keeping the OS updated.
Janet is worried that she needs to clean up her system and have a separate antivirus system. Leo says no. You don't. You don't need a third party cleaner and you don't need a separate AVS app. Windows Defender is just fine and it comes with Windows 10 for free. But even the best AVS isn't going to protect you against your own online behavior.
Al's antivirus software is up for renewal. Does he really have to pay for another year? Leo says no. Windows has its own antivirus called Windows Defender, and it's free. It does a really good job. There's also a possibility that third party antivirus software could make him more vulnerable to hackers, not less. Al will need to download their standalone uninstaller to get rid of that third party app. Then enable Windows Defender and keep it up to date. But he should remember, no antivirus can protect him from himself.
John bought an 9.7" iPad Pro. It came with antivirus software. Does he need it? Leo says absolutely not. In fact, it won't even work. Apple's iOS software sandboxes everything and Apple has to approve all apps, so unless he jailbreaks his iPad, he is completely secure. So he should throw away that AVS because he doesn't need it.
