Helping people with computers... one answer at a time.
Stopping real-time anti-virus scans opens you up for sudden virus attacks that you don't see coming. Sometimes, email scans are a different problem.
Is it really necessary to have a real-time anti-virus program running at all times using up resources? I have Avast anti-virus, but I also run a different manual online scan every day using Malwarebytes, anti-malware, and Super Antispyware, Bit Defender and others. I was wondering if I can uninstall my real-time Avast AV?
In this excerpt from Answercast #74, I look at the advantages of real-time scanning for viruses and spyware. Real-time scanning of email can be another story.
Well, it's a hard one to answer generically.
My recommendation in general is if you're not sure, have one. Have exactly one real-time anti-malware scanner working for you.
Now the reason I hesitate at all is because there are people who are experienced enough on the internet that they will actually never get infected. They will never accidentally cause something to download on their machine and infect it.
One would think that I would be such a person, and in fact, to the best of my knowledge, I have never actually invited malware on my machine. I would be a candidate for not running a real-time anti-malware scan. I'd run it anyway. In fact, I do run it anyway.
The fact is - it's simply too easy for things to kind-of sort-of slip by, sometimes. I have come very close to downloading and installing malware without realizing it. It's that "without realizing it" part that you want a real-time scanner there to protect you from.
Malware can infect your machine in seconds!
In other words, by the time you realize that what you just downloaded is in the process of infecting your machine... it's too late!
So, my recommendation in general is that yes, you should have one good anti-malware product that is keeping an eye out in real-time for the things that are happening on your machine. That way, you can be protected from things that might accidentally get to your computer.
If you are a person who is confident about always being able to identify something - and never, ever downloading it - then of course, feel free to skip the entire process. I just don't think that there are many people who fall into that category.
Now, I do want to clarify something about one real-time aspect that definitely can cause people problems when it's enabled: that is real-time email scanning.
Sometimes, the anti-malware software's real-time component, when applied to your email (in other words, as your email is being downloaded), can occasionally cause problems: everything from false positives to all of your email being deleted as it's downloaded.
My recommendation in general is to leave those features turned on. Just be
aware that they can cause that kind of a problem. If they do, then turn off
that and only that portion of the real-time scanning
component of your anti-malware software.
