Default Avast Newbie

Ok, all you Avast lovers, I'm ready to take the plunge!

After several years of using MSE, I'm ready to switch over to Avast. (I considered Bitdefender Free, AVG Free, and Qihoo 360, but decided to stick with the "favorite".)

Any suggestions on which shields to install or activate and which ones not to? Or, any suggestions in general for installing and using Avast?

Choose Custom Installation, which will give you options to control, and will also help you avoid Google Chrome, bundled with Avast. If you already have Chrome on your system, then that's not a bother .

Apart from the shields, there are other components, which you may choose to install or not. The ones I can remember are:

Software Updater - Keeps track of software on your computer, and tells you of an available update.

Browser Cleanup - A useful tool, which can help you get rid of the browser extras, like toolbar, and other things.

Webrep - A WOT like service, informing about good and bad sites, based on reputation from users.

It's upon you which to choose to install. I choose none of the above, since I do not need a software updater... I take care of that myself. I also manage and keep track of browser plugins/add-ons, etc, and I am confident of taking care of that without a third party software. So, I do not install the browser cleanup tool. However, it's a good one, useful to install on systems of less computer experienced. I use WOT, so I do not need webrep.

Among the various shields, I install all, except for Mail Shield. It's because I do not use an email client. If you do use one, then do install it.

On computers of people with less computer experience, I do not install the behavior shield, which throws alerts based on program's behavior, and often, these can be false positives. If you are confident to handle those alerts, install it.

It would be advisable to install File System Shield, Web Shield, Network Shield, and Script Shield.

P2P Shield, and IM Shield can be installed if you use P2P based programs, or, if you use instant messengers. Since I use both, I choose to install these shields too.

In the Settings, you should check to see if you want to be opted in for the services listed in the Community tab. If not, opt out of them.

Check other settings too, to set them according to what you want.

There is an AutoSandbox feature in Avast, which will pop up alert to let you run suspicious processes in its sandbox. If you don't want that, turn if off via settings of File System Shield. I keep it turned off.

Very comprehensive reply Anupam! Thank you! I'm actually going to print this out and save it for later this weekend when I install Avast.

One last question--I assume that from your perspective Avast runs light? I'm interested to see how light it is compared to MSE.

Oops....one more question--anyone have any issues using Sandboxie with Avast?

Yes, Avast runs quite light. It's surprising though, considering the number of components it has.. but it does run light. I had it installed even on my old computer with 512 MB RAM and P-III. It used to run decent on that. I have used it on different configuration of computers.. P-III, P-IV, to newer ones.. and on different Windows versions, from XP to Windows 8... and it runs light on all of them, without any problems.

And no, no trouble with Sandboxie either. In fact, Sandboxie has compatibility settings for it. When you install Avast, Sandboxie will pop up a dialogue for compatibility for Avast to be added. So, no trouble from there too.

You will be happy with Avast . I have been, since years.

When using either Opera Mail, Thunderbird or The Bat email clients under Sandboxie v4.05 there is a known conflict with Avast Mail Shield whereby emails fail to be sent or received.
If you're affected by this you'll either have to revert to Sandboxie v3.76 or disable the Avast Mail Shield until a fix is found. tzuk (creator of Sandboxie) is aware of this conflict.

Other than that, no probs!

Thanks for chipping in with that Sope, I was not aware of that.

Here's the latest tests from Raymond on Memory Usage Test to See Which is the Lightest Antivirus Software. Avast came out top with Webroot.

What's so typical about Avast is that it re-flushes the memory it uses every 10sec, so it wouldn't ever go above a certain threshold, which makes it comprehensively light compared to others..

Although I'd like to see some processor usage statistics and the article doesn't compare that.

And Anupam is right about behavioural shield. It does throws in a number of false positives. Although, I still have it enabled, because I just have to restore the file from the virus chest if I consider it safe enough and exclude the folder from scanning again.

Just finished installation. Man, lots and lots of options to install in custom install....

Some of the options I wasn't sure what they were or what they did so I just installed them. Now, I kind of wished that I hadn't.....

Do you set up a nightly full scan, a nightly quick scan, or no nightly scans at all?

Do I have to schedule updates (like I did with MSE) or does it update itself?

I don't bother with nightly scans, I just let the screensaver store data in persistent cache and make occasional Boot-time scans. The File System Shield is kept running of course.

Unnecessary, Avast updates itself around twice a day, and even takes care of missed updates and popular programs.

@Kendall, in addition to the conflict mentioned by Sope, there is another known conflict between Sandboxie and Avast. If has to do with the behavior blocker. You can read about the workarounds in this link.

http://www.sandboxie.com/index.php?KnownConflicts#avast

Kendall, you should know, based on what I seen, MSE gets along better with Sandboxie. The only time that there has been any conflict between Sandboxie and MSE was when MSE was first released. At first they were incompatible but once those issues were fixed, problems have never returned. At the same time, workarounds between Avast and Sandboxie are required at all times.
