Avast and AVG at the same time

nor69 · 07-25-2008, 12:43 AM

Your help would be most appreciated. Is it ok to have both Avast (free)and AVG (free) on the PC at the same time, provided the one which is not in use, is disabled. nor69

Theoretically, it should be OK as long as one is disabled. However, based on my personal experience, for various reasons, I would recommend that you remove/uninstall the one you're not using via Add or Remove Programs in Control Panel.

From what I've seen, running two AV programs simultaneously will completely kill performance. My friend had Norton AV and AVG running at the same time, and his machine was so slow it took almost 10 minutes to boot up because both programs would scan all the executables that his computer was trying to start.

Yes, correct. It's disastrous if both (or more, sometimes) AV applications are active at the same time. Not only would they slow down the system but also interfere with each other, and may even cause crashes.

However, the question was whether it would be OK if one was active while the other one disabled".

I think even that could potentially cause conflicts. I would advise against it, because it's not only completely pointless, but also has a cost in system resource overhead.

Agreed. That's why I said "I would recommend that you remove/uninstall the one you're not using via Add or Remove Programs in Control Panel."

I wish to thank all those who offered such sound advice. I will do as you suggest. Thank you again. nor69
