Which Zillya antivirus do I need?
Zillya sells three Windows licences. They are not different products with different engines — they are the same detection engine with progressively more modules around it. Choosing between them is a question of what else you want, not how well protected you are against viruses.
Start here: what do you use the computer for?
If the machine is mostly used offline or for light browsing, and Windows is kept up to date, Antivirus is enough. If you bank, shop or use webmail from it, take Internet Security for the firewall and anti-phishing. If the machine is shared with children or with other adults, take Total Security for parental control and privacy protection.
Zillya! Antivirus — $25
Virus, spyware and Trojan detection, the behavioural analyser, mail filtering and USB protection. The right choice if Windows is patched, you browse carefully, and you want a second detection engine rather than a suite. See Zillya! Antivirus.
Zillya! Internet Security — $31
Everything above plus a firewall, anti-phishing, anti-spam, a virtual keyboard for entering passwords, the PC optimiser and the file shredder. The right choice if you bank or shop online from the machine. See Zillya! Internet Security.
Zillya! Total Security — $37
Everything above plus parental control, the process manager, the startup manager and privacy protection, which clears traces of your activity from the PC. The right choice for a shared or family machine. See Zillya! Total Security.
What all three have in common
The same real-time guard, the same behavioural analyser (HIPS), the same heuristic analysis, the same mail filter and USB protection, the same signature database of over 15 million records updated daily, the same 15-day free trial, and the same licence terms: one Windows device, 365 days from activation, no automatic renewal.
You can see the modules side by side on the product comparison page, and read how delivery works on licence keys and activation.
What none of them do
They are Windows products. There is no macOS, Linux, iOS or Android licence in this range. They are one-device licences — if you need to cover several machines, buy one licence per machine, or ask us about a business quotation, which is priced per endpoint and centrally managed.
System requirements
Identical across the three: 1 GHz processor or faster, 1 GB RAM, 1500 MB free disk space, screen resolution 1024×768 or higher. Supported Windows versions run from Windows XP SP3 through Windows 7, 8, 8.1, 10 and 11, in both 32-bit and 64-bit editions. The wide OS support is worth knowing if you still run an older machine that newer suites have dropped.
