Antimalware Service Executable

[Staxxx21]

Hi I would like to ask how much RAM does yours PC's Antimalware Service executable take?

Panda Cloud Free is using a mere 10 MB. That's why I use it.

Oh I am using Microsoft Defender and it uses 200-500 MB and do you think its normal

?

It's normal defender uses a lot of ram and it's detection rates are not the best by any means.

My antimalware is a reformat and clean install.

A lot of antivirus software will store signatures in RAM.  I wouldn't worry about it unless your device doesn't have much RAM.  RAM is meant to be a cache, and so let programs use it as they need, provided they don't use too much. 

 

Having antimalware signatures in RAM makes detection much faster because it can compare signatures to files pretty much at runtime.  Some antivirus software can be very light on RAM, but is usually quite heavy on the disk and the CPU making it worse than if it just used a few hundred MB more RAM.  

 

There is also the potential that the process is experiencing a memory leak.  Should be fine though as long as it's under 500MB. 

 

Hope this helps.

My Panda Cloud Free is only using 1 to 3% CPU.

While I would have agreed with you a decade ago, and I understand that if you know your way around the internet you're at lower risk of getting infected, I think that spreading this kind of information can put users at real risk. 

 

1. Advanced Exploit Kits are on the rise, and there have been cases in the past of malicious actors putting an ad on a website with an exploit kit linked which will exploit a browser vulnerability or an operating system vulnerability. 
2. Malware behavior has changed, back in the day malware would be much more obvious, some level of destruction would always be caused by malware - but now more and more malware is designed to run in memory, exfiltrate data from common password locations like browsers.   
   
   With the rise in ransomware, it also means that your data may be gone - even if you backup to the cloud.  Simply because any linked shares or devices will be encrypted also.  

 

One thing you are pretty spot on with though:  Antimalware today is all around pretty useless.  

 

Motto of the story: If you're not an IT expert, use an antivirus in case you download a sus file - regardless of who you are or what you do, patch your stuff.
