Spyware, cryptojacking, keylogers

[Nikola Miljevski]

Hello,

 

I have read elsewhere that it is impossible to confirm with 100% accuracy if one has spyware, cryptojacking, keyloggers and such things on his/her computer or mobile phone, without proper forensic analysis. 

 

My question is, what is the maximum that can be done with Kaspersky Lab software for home users in detecting such malware. Suppose that such things may have been installed before installing any of the Kaspersky Lab software.

Hello @Nikola Miljevski, Welcome.

Almost every malware needs your help to become active. So it is up to you how well your system is protected.

• Keep your OS up to date
• do not install software from dubious sources
• do not use cracks
• do not use keygens
• do not allow updates for program xyz (Adobe Reader or similar) if a website tells you so
• download software only directly from the manufacturer
• do not open e-mail attachments from senders you do not know
• never enable macro execution in Office, if the document asks for it, check with the sender
• activate the file extension view in windows also for known file types, then you can see that xyz.pdf is actually xyz.pdf.exe and is very suspicious.

With this and some other tips you have already prevented 90% of infections.

The default settings of Kaspersky software are a good compromise between performance and protection. They are suitable for most users.
If you want, you can secure your system even further. However, this requires expert knowledge and is not suitable for the average user.

If malware is already present on the computer during the installation, this is either reported or the installation is aborted.
After the successful installation, a complete scan should be started in any case.

Thank you very much for your help.

Anyway, this doesn’t answer all of my concerns. 

I was asking about maximum possible security that Kaspersky software for home users is capable of, especially in detecting possible malware stated in the subject of my question.

I am fully aware that such things can’t be explained in a reply to my post, so I would be very thankful if there is some kind of a manual (possibly in pdf format, possibly very huge 😀 ), where such things as explained in details. 

Then again, I read elsewhere that no security software can confirm with 100% accuracy that there is no malware on the computer or phone. Is this true? I can find the links and post them in my next reply if required.

Hi @Nikola Miljevski,
your sources are correct.

Good AV programs can detect close to 100%, but never the whole 100%.
Malware authors always find new ways that no one has ever thought of. Also in operating systems and user programs there will always be undiscovered vulnerabilities that can be used for attacks.

The AV manufacturers such as Kaspersky try everything to detect malware by its behavior. But there will never be 100% security. The hunted is always one step ahead of the hunter.

Thank you very much @Schulte for your time and explanation!
