Malware Fighter Excessive CPU Usage

Can try setting scan priority to low in scan settings.

I just did that and CPU is still way too high, over 60% to over 70%.  It should be less than that on medium priority.

Is it high for the entire time it is scanning, or just at the beginning. It is quite normal for a scan to use maximum cpu when it begins and then it drops right

down as the scan progresses.

For the entire time.

Did you try uninstalling and re-installing, in case there is a corruption in the program.

No I haven't.  I don't believe there is corruption, as I know others who have the same issue.  Apparently ASC Ultimate is lighter.

What are the specs of PC? 

i5 2400 CPU with 6GB of RAM.  While not particularly powerful, it is more than fast enough for an antivirus to be able to run scans without excessive CPU use.

I have looked for others reporting this issue, and I have not found any.

Again, I suggest you try a complete uninstall and re-install.

To me seems quite normal to see increase of CPU usage at the beginning of scan. Even tho I have a ryzen 9 5900 X (I set priority to high) and see a load on the CPU with fans speed up

Roger_M has already said that his cpu is high for the entire scan

I uninstalled, rebooted and then reinstalled it.  The result was the same, as I had expected.  I then uninstalled it again and installed a trial of ASC Ultimate.  With the default settings, CPU usage is between 24% and 34% when scanning.  Which is perfectly acceptable.

This is from a user at MalwareTips who experienced the same problem.

Iobit Malware fighter is still too heavy for my liking, but Advanced System Care Ultimate is actually pretty good. I like it better than Bitdefender Antivirus and the detection rate is within 1-2% of Bitdefender's antivirus so it's detection rate is pretty good and they are constantly improving the engine for zero day threats as well.

As well as that, a while back there were some posts at Wilders with someone also experiencing very CPU (and RAM) USE with IMF 8, but I was not able to find the psots again.

How long have you been using IMF, and did you have this issue from the first time you used it, or did it start later???

Right from when I first used it, and this is on a clean install of Windows 10.

IMF 9 is in development. I don’t think is available yet, probably he uses IMF v8.6

That was a copy/paste error. I have corrected it. Thank you for pointing it out.

Is this the first version of IMF you have used, or did you have the previous version, and if so, did it have the same CPU issue.

I have used previous versions of IMF, on different computers and didn't have this issue.  However, I'm not sure the last version I used, other than this one, where I took note of CPU usage, as it's been quite some time, since I used IMF as my antivirus on the main computer I use.

Open your Task manager and then run a scan in IMF.

See if IMF is responsible for all the increased CPU usage or if other processes are using CPU, due to the scan.

IMF may be causing other processes to activate.

IMF is the sole cause of the CPU use.  I was not looking at total CPU usage, only CPU use from the IMF processes.

If IMF is using 90% CPU, then your machine would become almost unusable, as 10% available CPU would not be enough

to perform other functions.

I assume that when you ran your first scan with IMF, that you allowed the scan to fully complete.

I ask this, because when IMF is first installed it runs a full scan to check your system,which uses a lot of resources.

Subsequent scans should then run with much less resource usage.

I had never run a Full Scan.  This is something I usually avoid with all antiviruses.  However, I just did a custom scan of C and let it complete.  I didn't run a Full Scan, as there a 25 partitions on this system, so t would take a very long time.  Running the scan of C did not reduce CPU use on subsequent scans.  Also, it's important to note that with ASC Ultimate there was no excessive CPU use, even on the very first scan.
