Purchased tweakbit and used for one year. I did not opt to renew. My computer fell victim to ransomware. I used malwarebytes to regain control of my computer. All information points to tweakbit as the source of the ransomware. The next year I received a notice from tweakbit stating that my subscription was getting ready to auto renew. I had terminated the contract and had not had their service for a year. I contacted the credit card company just in time to stop them. These people are a bit scary.
