I've been using AVG and Malwarebytes together for some time now. Malwarebytes since it's beta. I repair computers for a living, and recommend both to my customers. Most all of my customers have both, and I see a flood of calls coming (Thanks AVG) . This must have been the recent update from AVG, as I installed both on computers in the shop yesterday, and did not get the AVG warning. I trust they will have another update to fix the problem quickly, as they usually are very fast at resolving issues. So please don't get in a panic just yet. Enough reports to AVG, and they will address it promptly.
