How do you know if you have caught a virus?

Question

Malware

Let's say I downloaded virtual boh. I installed something in the virtual machine. It's viral, but I'll notice it in a week, could it be?
Of course the sandbox won't work for a week. Are there any viruses that you can't detect right away? I want to download an illustrator crack for my game, but I want to be safe.

Answer 1

Without analysis, you may not even notice in a year.

Answer 2

Until you install / run - you can not find it. And checking the file on virustotal.com might not show anything, at least not right away. The malware can also check whether it is running in a virtual machine.
There are many nuances and you can either not notice anything on your own, or it will be too late, you will pick up a cryptographer, for example. Or a miner, recently with crack-repacks, they have gone very difficult to remove.
Turn to specialists, but rather do not take risks, the consequences can be sad.

Answer 3

In your case, you can use sandboxie. And so, even an advanced user (and even a pro) no matter what tools he uses - there is no 100% guarantee of detection. This is where the price of malware sources starts from 10k bucks.
