I got an update-memo from my anti-virus program; I rarely have problems with them but when I "updated", it affected my computer to the point I had to run a System Restore action. So I hope others who use and enjoy Avast (free version) will be aware of possible corruption...especially AVAST! C'mon you guys; please work out the bugs; I'm not going to update as long as that problem exists. I'll use another free program, of which there are many.
