I am using the Pro edition,on my gaming pc I have IE only…on my business pc I have IE,Chrome and Firefox ( can’t log in using any of these), on my business pc I have cleaned the temp files and cookies…NOT on my gaming one ( have not gotten around to it yet). Also, on my business pc I ran Avast to look for a virus after I ran a malware program. Avast found one bad file and asked me what I wanted to do…so I deleted it. It then asked me if I wanted to do another scan…I thought may as well. I clicked yes and it took me to a DOS like screen…white figures on a black screen. I let it run and it said it found a number of infected files…asked if I wanted to delete them…I clicked YES…when it was all done I rebooted and now my pc can’t even connect to the internet now. It’s wireless of course and my pc can’t find anything…I assume Avast! deleted something it should not have.
