I don't support having to shut down the AV particularly when notified to do so by a pop-up. Too many bad things can happen. I have for years upgraded versions of Adobe Shockwave and both Flash Players (IE and non-IE), and never had to shut down my AV. There have been several Flash upgrades recently in a short period of time, and a new Release Candidate for IE v10.3.181.5 is now being offered. I can only warn, if you get any popup telling you to turn off your AV regardless of the focus application don't. Research the offering by going to the manufacturer's homepage or a trusted download site, CNET, Filehippo, Major Geeks just to name a few. Finally, after doing your homework, and if you still have doubt come here. Again, when it comes to turning off your AV you cannot ever be overly cautious. DA

Because I loaded it on my computer and it screws everything up, and makes the computer lock up, no matter if it's IE or Firefox. One more thing I'm blaming on Vista, just because I hate it. Of course my AVG and Firefox is fighting all the time too, as is AVG and this site. well, none of that happens here at Elery's with his Mac, only at home with my Dell. Annie

I would uninstall it (do not delete it) thru Add/Remove programs in Control Panel and make sure you install the free version of Avast

I removed Avast and reloaded it and now the message stays up longer so I an report more detail.
