How can I protect from malware
No matter how many types of malware are there, but the good thing is that there are many ways to protect your computer from malware.
Keep your operating system and applications up to date, as cybercriminals look for vulnerabilities in outdated or outdated software, so be sure to install software updates as they become available.
Never accidentally click on a pop-up display link. Rather close the message by clicking on the “X” in the top right corner and thus the display link stays away from the incoming website.
If your devices do not have anti-virus, then use a good paid antivirus, which protects the personal data and information of your computer, tablet, Mac or smartphone from online threats.
Avoid clicking on any unknown url link. Whether it came via email, social networking site or text message, if a url link seems to be uninformed, stay away from it.
Beware of emails that collect personal information. If an email comes from the bank and instructs you to click on that email link or reset password or access your account, do not click it. You directly go to your online banking site and log in from there.
Do not open an unknown email attachment unless you know what the email is, even if it came from an acquaintance or an unfamiliar person.
If you think my device may be infected, scan your device with the anti-virus software you have installed.
