I'm an AVAST user. For years, AVG has been well-known to bring good computers to their knees. I specifically remember an entire classroom of computers slowing to a near stand-still because AVG initiated a scan. Presentations had to be halted, etc... For years afterward, every computer that had AVG was very slow and when switched to AVAST, speed up immensely. If Avast even hints at becoming slower after this buyout, I'm finding a new antivirus. I have no loyalty.
