I disagree. I have used Avast Free from time to time, & still use MBAM Free occasionally for 3rd opinion on-demand scans. I have never been tempted to buy their non-free products. My *main* security apps are not free now & never were. They offered a 30-day trial. I tried them then bought. The ox who plows the field is worthy to be fed. Now -- as to HMP not cleaning up after it detects: I find it difficult to understand why anyone would want an AV to clean malware. Such clean-ups are not always a 100% certainty. IMO, it's much better to image one's system disk at least weekly & retain 3-4 months of prior images( FIFO). The best cure for an infection this week is to restore a healthy image from a prior week.
