Could all end in tears I suppose. Had a few disaster threads :)
The idea here is to mention the Freebie anti-malware apps you like - with a link & a reason or description.
All I will briefly say about this oldie but a goldie is that the company is 100% trustworthy, the app works great and will deal with most threats same as (paid) McAfee.
Can you point me to a better Freebie?
