iolo is the company behind several internet security products, including a system tune-up tool for Windows PCs and an anti-malware engine. In terms of system optimization, it’s pretty good, and iolo can do some cool things like recover deleted files and erase entire drives.
But the anti-malware engine is not the best (it missed a few samples in my test). If you’re looking for an antivirus, choose one of the best antivirus packages of 2020 instead.
If you’re looking for an excellent system optimizer with an even better antivirus engine, I’d recommend Avira Prime, which also has a VPN, a password manager, and a privacy optimizer.
But if you’re only looking for a PC tune-up tool, iolo is not a bad choice.
