For many years I have been the on-call computer tech guy for family members, friends and clients and most of my “repair” jobs involve clearing out malware infestations “hijacked browsers, rampant pop-ups, hidden files etc. Every personal computer owner must protect it against viruses just like the experts in large companies. Computer security is dependent on antivirus software. New worms and programs are being developed all the time. Some viruses target specific files, like word documents, outlook, or excel spreadsheets. Other more malicious programs can shut down or format your computer.
How would you like to turn on your computer and see a message demanding that you pay ransom to access?
Free Vs paid antivirus
Free antivirus software generally only searches your computer using signature-based detection which involves looking for patterns of data that are known to be related to already identified malware. Paid antivirus will catch new threats and offer extra protection to your system.
There are a lot of hackers in world, who every minute make and spread millions of new viruses. They hack and collect information like your social media login details, email or ATM password, your bank account and private information.
Other attacks are just for fun to destroy computers. You must have experienced, sometimes in your window that your antivirus stops working, your files automatically get hidden or deleted, your internet connection becomes very slow, your window crashes. All these are effects of malware programs. So you need to install good Antivirus software to detect and remove viruses before they do harm your computer.
