How to Protect Your Computer from Viruses and Hackers
Virus:
A computer virus is a computer program that can replicate itself and spread from one computer to another. The term "virus" is also commonly, but erroneously, used to refer to other types of malware, including but not limited to adware and spyware programs that do not have a reproductive ability
Malware includes computer viruses, computer worms, ransomware, trojan horses, keyloggers, most rootkits, spyware, dishonest adware, malicious BHOs and other malicious software. The majority of active malware threats are usually trojans or worms rather than viruses. Malware such as trojan horses and worms is sometimes confused with viruses, which are technically different: a worm can exploit security vulnerabilities to spread itself automatically to other computers through networks, while a trojan horse is a program that appears harmless but hides malicious functions. Worms and trojan horses, like viruses, may harm a computer system's data or performance. Some viruses and other malware have symptoms noticeable to the computer user, but many are surreptitious or simply do nothing to call attention to themselves. Some viruses do nothing beyond reproducing themselves.How to Protect Your Computer from Viruses and Hackers???
1) Put Your Firewall On.
A firewall protects you against:
* Hackers breaking into your computer.

Blocking pop-ups is not enough. You have to set your browser either to the medium or high security level. This will help your browser block registered malicious websites or scripts.

1.There are so many free reliable anti-viruses online.
2.Google has one, which can be downloaded via Google Pack.

is good enough to protect your computer.
4.You may read some reviews and choose which is best for you.
5.On the other hand, if you think that you need higher protections,

4)Assigning Passwords is in Combination.
1.As technology is rapidly advancing
especially in communication and social networks, hackers are also
having more avenues to steal your information and files.

your passwords. Instead of “techie” you can make it “techie#123”. Use a
