How Often Should You Scan Your Computer for Malware?

There isn’t any security text book or ‘Must Follow’ guide on how often you should get your computer scanned for Malware such as Virus, Trojan, and Worms.

It is always good to scan as much as possible to ensure that your are safe from any infection.

The situation where you need a scan need to take place

Let’s not talk about how regular you should scan first. Instead, let’s talk on when is the time that you think that a scan should be executed. The points below are the situation where I think a scan needs to take action immediately.

  • When you start to experience your computer performance is slowing down.
  • When you experience an unknown error from your Operating System.
  • When you have 100% of CPU usage during idle mode.
  • When you hit 2-3 times of blue screen in a single day.
  • When all your applications are normally functioning suddenly malfunctioned.

There might be more situation where you need to perform a scan apart from the above points mentioned. So whenever you feel that your computer is not behaving like usual, don’t be shy and start scanning. Even if you can’t find any infection, at least you get an answer that your computer is currently safe.

Remember that it is always better to be SAFE than SORRY

As for regular scan, try to schedule it at the time where you are not using your computer. For instance, I usually schedule my scan around 1:00 a.m. where I should already lying on the bed sleeping like a pig. I don’t scan my computer when I am using my computer for my regular work unless it is necessary.

Did I just forget to tell you about how often you need to scan your computer?

Of course I didn’t because it is the main objective of this post. So now, how often do you think you need to scan your computer? I would say why not just scan your computer on a daily basis. I’m not going nuts here and I am serious about scanning it daily.

Why scanning your computer daily can be possible? Basically, my suggestion is to perform a critical scan or quick scan daily where this type of scan will only scan for all the important area. Most antivirus today comes with this type of scan and usually, a quick scan can be pretty fast. You might be able to finish the scan in just a one hour lunch break.

Of course a quick scan is never enough for security. You need to perform a full system scan as well. That I would recommend to scan on a weekly basis where I usually schedule my full system scan on weekends. If you are unable to do so where you might be on some tight schedule, try to perform a full system scan at least once a month.

As I am about to end this post, I would like everyone to know that this post is part of a sneak preview of my security eBook which I am going to release it anytime in these two weeks. I am still in the stage to write the final section of the book and once I complete proof reading it, I will release it to everyone for Free.

    Do you know how to scan website for malware instead? I got my site infected by mulware 2 months ago.

    I think you should scan your computer everyday with updated Anti virus because it decreases the chance of having a malware but increases your computer life span.

    What I usually do is do a FULL automatic or scheduled scan at 1-3 am in the morning. These are the times that I sleep. So that when I wake up in the Morning, I have a “clean” and fast PC setup.

    It is always emphasized that ensuring that the network and all other systems and data carried in them is safe, security has to be monitored throughout and this is through computer scans and updates to security software.

    Interesting post Alan, I found it whilst searching through your archives ๐Ÿ™‚

    Interesting that you feel you need to scan on a weekly basis. I think it depends on the type of protection you have and how secure it is. I have my anti-virus set to scan every file on read, write and rename, so it is pretty rigorous. I have a relatively powerful PC, so I don’t see that much of a difference in speed. As a result I only scan my PC once every month or so.

    If you have a less powerful PC and your anti-virus set to a less secure setting (less scanning = less secure but faster PC) then I think a weekly scan is a good idea.

    What sort of scan are we talking about though? An extensive scan or just a quick one?

    Interesting topic to discuss Alan, I would like to know your thoughts on my views ๐Ÿ™‚
