Been using the Free version for about 10 years, and the IS for the last 3. This year's Safe Zone has a huge problem with Flash Player. No sooner than my bank log-in page loads, Flash crashes, and Safe Zone hangs for hours. You cannot shut down using Ctrl-Alt-Del, or right-clicking for the Task Mgr--nothing happens. I was forced to hold the power button down, which logs tons of Windows errors. 15 printed pages to be exact. I spoke to Natalia at Bulgar, Avast's remote-service contractor, who was pleasant enough and offered to have a technician remotely repair my windows for the low, low price of $179. Hell, for another $100, I could probably go to a 4th of July sale and buy a new Windows 8 desktop. I'm still on VISTA.... Naturally, I felt that AVAST should repair my Windows error report for free since their software caused the damage. However, since then I have gone back to a restore point before I installed Avast on this computer. There are no longer any AVAST errors on the log, but tons of others that mean nothing to me. Anyway, there is a major issue with this software.....caveat emptor. :'
