Established solution
Deep scanning

After two weeks, it reverts to the basic free version. This has to be activated manually, but is still a top-notch security tool. We recommend running it at least once a week to check or any nasties that you haven't noticed, or if you notice that your web browser has suddenly started acting strangely (likely a result of adware).

It’s also available free, and along with Anti-Malware, is a great addition to your security toolkit.
