Hi, I'm new, sorry if this has been asked. I'm using the Avast free version and, with verification by three pieces of different but compatible anti-virus software, my computer is virus free. However, every time Avast updates (which is often), my computer slows down to what looks like it freezes -- I can't even move the mouse. After the automatic update, everything comes back. Given how often Avast updates (I do value the promptness of the updates), this has become really annoying. Anyone has insight? I'd truly appreciate! ^__^
