I must disagree with David. I have been in the computer sales and service field for over 25 years and must say that I have found Avast to be one of the worst antivirus programs on the market, surpassed only by AVG in its ineptitude. The programs that I recommend and sell to my clients at this point is Kaspersky Antivirus.
To answer your question directly, yes, Avast can slow down your machine as it can be set up incorrectly to do more scans than are necessary. Just like what Norton Antivirus allowed people to do about a decade ago (which is what soured people against their software), Avast can be set to scan files each time they are accessed, created, edited, deleted, or closed or some combination of these various file operations. Some people feel that having the software scan files at all stages of file operation is advisable and necessary. Doing so means that it can bring a machine to a crawl. In the most extreme example, I once saw a client's machine take over half an hour just to boot to the desktop. Most antivirus programs do not allow access to those options precisely for this reason. Instead, they allow the configuration of what should be scanned (Smart Scan (it selects the appropriate files to scan), Extension List (it scans files based on a certain configurable list of extensions), or user-configurable (the user gets to set whatever he wishes to have scanned).
Also, Avast can slow down your machine indirectly because of the multitude of infections that it fails to detect. It is not uncommon for me to have a machine come in that is allegedly protected by Avast and the user is complaining about the machine not working correctly or running slowly and when I scan it with Kaspersky, I find up to 3000 infections that were missed. Once those are removed, even if Avast is left on the machine, the machine works worlds better, though after showing easily that Avast is inferior, most clients ask me to put on Kaspersky, after which they do not have problems anymore.
If you are looking for an antivirus that is better than Avast and do not wish to pay for a commercial product, then I recommend Avira. You can get their free product at http://www.avira.com/en/avira-free-antivirus I have recommended and used them for certain clients over the years and while it is not as good as a commercial product (you get what you pay for, after all), it is definitely the best of the freebies.
If you have any other questions or need further advice, feel free to drop me a line.
Maybe. If your computer was slow when you bought it, then Avast will slow it down more (but so will any antivirus program). But it's a worthwhile trade-off for avoiding viruses which can slow your computer down a LOT.
I'm a computer tech who have been doing this professionally (as in doing it as a primary job) for 10 years, and I often install Avast on client's machines because it's a fairly good antivirus and doesn't slow the computer down very much. Most people won't even notice any slow down.
Yes it does. If you are looking for a good and fast free antivirus, try Avira.
No, it will not slow down your computer and no it will not give you virus
Probably, if it is a big game then it will most probably slow it down.
No but it can slow your laptop or computer down a bit. I myself wouldn't go on it because exploring all the downloads I have a slow enough laptop and my computer is completely crashed. Good luck!
Roblox can slow down your computer. Don't get me wrong though, it won't affect your laptop much as it is only a 250 MB game with barely any graphics. If you have 6-8 GB ram and 2.5 GHz, your computer can run Roblox easily. You won't notice ROBLOX slowing down your computer. If you have a 2011 type of laptop, THEN you would notice your laptop slowing down. So if you have a new laptop, you don't need to worry that roblox can slow down your computer
It will not slow down your computer, but the process of writing the file to your drive is slower because it is normally slower to write straight to your hard disk than to your flash drive. So it may take longer to download the file.
AVG updates are totally a waste of time because they only slow down ones computer. The AVG updates are best to be avoided and turned off immediately when installed on ones computer.
I really wouldn't suggest it. Anti-Virus programs can clash and slow down your computer a lot. You dont need both. Use either AVG or Norton. AVG is better in my opinion.
Norton - slow down you computer performance, It use lot of your PC resources. Avg affect less on PC performance when compare with Norton. I have use both of them, now I'm using AVG
Yes, combat arms does slow your computer down.
Yes, they can take up a lot of RAM and slow down a computer.
Any program that runs can slow your computer down, so yes.

While it's running, yes. It will not slow down you computer unless you are actively using it.
No. It is the viruses you download with the songs using LimeWire that slow your computer down.
No, it will not slow down your computer and no it will not give you virus
