Is this antivirus great? I have been using it for years, and i was told that it slows down the computer by a lot. Is this true?Is it a RAM hogger?

Usually when people say it slows down a computer, they mean it uses a lot of CPU, not RAM. You then have to ask what CPU they are using. If they are using a older computer, then it may appear to them that it is slowing down their computer. In my experience Avast does not use a lot of cpu. But I am running a Intel Dual Core, which is a recent cpu.

With all due respect, RAM (or the lack of) can absolutely slow down a computer.


Older computers contained much less physical RAM than is found in today's systems.


Lack of adequate physical RAM leads to excessive paging, which will slow most computers to a crawl.


Excessive paging results when RAM runs low/out and the HDD pagefile is forced into action as virtual memory to supplement the RAM. Since virtual memory relies on the HDD, a much slower moving piece of hardware as compared to RAM, system slowness is expected.


The CPU is definitely another item to look at, especially if single core.


How much RAM do you have?

Using Avast will use far less RAM and other resources than the viruses would. Well actually I'm wrong; the viruses will use less since your machine won't work properly.

I've been using Avast for 4 or 5 years now and have to say that it's totally great. it's free, and it doesn't slow down my pc, althought I have a rather powerful, so I haven't got any problems. In addition, to my mind it's the best free antivirus with good protection system.
If you don't feel any problems in your pc's work, so don't worry and keep using Avast.
