Answer:
There are many possible indications that the Operating system on
a laptop has been hacked, here are some important ones:
1 Repeated pop-up at random
- This is one of the most explicit signs of being infected by a
machine.
- This is a poor indication if you start getting more irritating
pop-ups in your web window, and they sometimes flash on pages that
don't normally generate pop-ups.
2 Shutdown of antivirus
- Disable the antivirus or anti-malware programs for certain
forms of malware and making it impossible to re-enable them.
- It is very possible that your machine has been compromised with
ransomware if you find that your antivirus has abruptly stopped
running and you can't access the Task Manager properly.
3 Applications that you didn't install turn
up
- In order to sneak onto your device, a malicious program can be
disguised as legitimate software.
- Typically, worms or ransomware that connect to other
applications is used as a package to get installed together.
- So, if you find your machine residing on an unfamiliar
application, it's possibly a malicious one.
4 The codes are not running anymore
- It may imply that you have fallen into a phishing pit by being
shut out of your online accounts.
- A typical use of tactical scammers is to send an
authentic-looking email from a bank or some other service you're
signed up for, by selecting the included connection to change your
password.
- You supply hackers with passwords to your account if you do
so.
5 Fraudulent emails that were sent from your
inbox
- If your email has been infected by a virus, it can attempt to
propagate further by sending malicious emails to your
contacts.
- It doesn't automatically indicate that they compromised your
computer.
- However, if your name and email address are used in the bogus
email, it is possible that your machine has been compromised.
