Now, that we know about popular computer viruses. It’s time we talk about the latest computer viruses that have evolved recently and how to stay protected from these malicious computer viruses.
Preventive Measures to Stay Secure From A Computer Virus Attack
The obvious answer to this is we should use an updated and best anti-virus capable of detecting the latest computer virus. In addition to this, using a data recovery wizard tool like EaseUS is also recommended. This tool helps recover files deleted by the computer virus, an example of which was seen during the WannaCary attack.

How was the malware downloaded?
The malware worm was downloaded by clicking on an attachment named ‘LOVE-LETTER-FOR-YOU.TXT.vbs’.
Once ILOVEYOU gets into the system it overwrites system files, personal files and spreads itself all over the system.
Researchers found about the virus and made people aware of it but no one paid attention and many machines were compromised.
Not only thins ILOVEYOU was so popular that it got a place in the Guinness World Record as the most ‘virulent’ virus of all time.
