About Outpost Antivirus Pro (discontinued)
Outpost Antivirus Pro was a security program from Agnitum, a company from St Petersburg known for its Outpost Firewall. The Outpost product line has been discontinued: in December 2015 Yandex acquired Agnitum's technology, all sales of Outpost stopped, and virus-definition updates, bug fixes and support ended on 31 December 2016. Agnitum's website closed in February 2017.
An antivirus without updates cannot protect you against new threats, so Outpost should no longer be used. Avoid copies offered on other websites.
What to use instead
- Microsoft Defender – built into Windows 10 and 11, free and always up to date.
- AVG AntiVirus Free – a free antivirus for Windows, Mac, Android and iOS.
- SUPERAntiSpyware – an extra anti-malware scanner that works alongside your antivirus.
