Thanks for the tip. I did as you suggested and find out my version is 0431-0. Clearly, the updates aren't being made. This is reasonable to me as I changed from ISP Earthlink to Comcast cable and the old version of Avast was downloaded while on Earthlink.
Based on this, is it best to just download the software again or should I delete the old version first then download the new?
I'm sooooooooooo confused!
Thanks for any help -
