which seem to refer to Uninstalling Avast Anti-virus.If you have an older avast before you install the new......
Two other experts told me that the protection between free and paid versions of Avast doesn't vary at all, that the paid version only differs by having real time active virus protection that's automatic and doesn't require the user to run the program every so often.avast! 5.0 comparison http://www.avast.com/comparison-chart
Simpler than the detailed directions from Bob, which seem to refer to Uninstalling Avast Anti-virus.The link I provided covers installation of avast! and steps that need to be taken if you already have an AV program on you system.
The AV protection between paid and free version is: none.The free version checks for updates every 4 hours vs the paid versions every hour
Free updates as frequently as the paid does, fully automatic.
You don't have a script shield on the free version and no virtualization feature.No browser is secure and using Common sense to not visit bad sites and keeping the operating system up to date is important.
It's your decision if you need that.
When using Firefox as a browser, you are doing very well with the free version. I'd recommend trying that first and see.
VLk, I think people also should mention what connection they have (dl speed/ul speed) and what browser they are using.
I'm getting lots of complains about slow internet/systems when people are using the latest IE version.
Perhaps that has something to do with it.
Firefox is no safer than any other browser and they should be up to date.
