iolo: System Mechanic PC clean-up software and add-on privacy tools

Shopping at iolo? See all current iolo discount codes and deals, checked regularly.

iolo has been making Windows utility software since 1998 and is now part of RealDefense, based in California. Its main product is System Mechanic, a maintenance tool for Windows PCs: it clears out temporary and junk files, lets you manage programs that start up with Windows, wipes browsing history and runs its jobs in the background when the computer is idle. Around it sits a small family of extra tools for security, privacy and passwords.

It's best suited to people who'd rather have one program look after routine Windows housekeeping than do it by hand. One licence covers all the personal computers in your home, and each purchase includes a year of updates, after which you renew to keep getting them. iolo also runs LiveTech, a paid 24/7 remote support service, for anyone who would rather have a technician sort out a PC problem for them.

The three System Mechanic editions build on each other. The standard System Mechanic does the clean-up and maintenance jobs. System Mechanic Pro adds antivirus, file recovery and hard drive protection, and System Mechanic Ultimate Defense adds privacy tools and a password manager on top. If you already have antivirus you're happy with, the standard version may be all you need.

The add-ons can also be bought on their own. ioloVPN encrypts your connection on Windows and Android, Privacy Guardian clears cookies and limits tracking while you browse, and ByePass+ stores your passwords and card details in encrypted form and fills them in for you. Each price includes a year of updates, with renewal afterwards, and System Mechanic itself only runs on Windows.

How to save more

• Start with System Mechanic Free and only upgrade if you find you want the extra features.
• Prices are in US dollars, so a card without foreign transaction fees will save you a little. VAT may be added at checkout.
• Decide whether you want automatic renewal when you buy, and note your renewal date. Refunds are available within 30 days, but iolo keeps a 15% processing fee, so it's better to be sure first.
