In this 21st century, computers have a come a long way with respect to development, since the arrival of top-class technology advancement. This has effectively (or sometimes negatively) changed how we interact and proceed with our daily lives. Everyone prefers the easiest, legitimate way to achieve set goals. This is good for business, but there is a down-side. Security threats. Yes! Security is compromised regardless of how water/virus/proof/data – tight websites and service providers demonstrate the safety of your data.
This is because you are actually giving documents to someone to keep, thereby granting them access. The blame mostly goes to the end-users as they lack the technical knowledge on how data theft occurs. You hear words like Computer Virus, Spyware and even Hacking. What do they even mean?
A Computer Virus is a small software program that can spread from one computer system to another and cause interferences with computer operations. A computer virus has the capacity to corrupt or delete data on your computer and it can use an e-mail program to spread the virus to other email addresses in your online address book. In a worst case scenario, it can even delete everything on your hard disk (I am sure you know how much files can be saved on a hard disk with a large size, usually in gigabytes).
How can this be prevented?
Keeping Your Computer Virus Free
Having a computer-virus attack has become an imminent encounter due to increased internet activities these days and as such, users should be able to stay abreast of the situation. There are a couple of things that can be done to prevent a virus attack on your computer and guarantee the safety of your files. Some of these safety steps include:
- Installing antivirus software on your computer system. Also, keeping it updated regularly is necessary as new virus come up every day. Updating the antivirus also updates its virus definition which in turn marks new virus as they are created.
- In these times of quick information delivery, attachments are sent as scanned documents. Sometimes virus travels by email and arrives as an attachment. The idle thing to do is to scan all attachments before you download or open them. It is advisable not to open if there is any suspicion detected.
- Catching any virus as it enters your system can only be done effectively through regular scanning. A thorough system scan weekly eliminates your chances of being attacked by computer viruses.
- It is also recommended for users to download files carefully and only when necessary while also surfing the internet carefully. Visit trusted websites and review every advice on malicious websites too.
A computer virus is not the only threat to our computer system as spyware is also growing and global threat. Spyware is software that is installed on a computing device without the end user’s knowledge. Such software is controversial because even though it is sometimes installed for relatively innocuous reasons, it can violate the end user’s privacy.
This also has the potential to be abused. Take, for instance, a mother installing spyware on her child’s computer system so as to monitor his / her internet activities. Also, spyware being installed on corporate computers to monitor company staff internet activities.
These are not considered spyware in a way because the end users know about their existence as a form of data collection. However, computers and other devices get infected with spyware negatively, through downloading of applications. The spyware is embedded in the download as a side application which can make use of components of the computers or mobile phone. Components like the camera and microphone, to monitor streets, or record conversations and keystrokes for future use.
Some ways of preventing this is to download a reputable and reliable antivirus software, complete with antispyware. This detects spyware on the system as they are not easily detected via other means. A noticeable trait of spyware includes the reduction in ram speed or a sudden drop in battery level in mobile devices.
To also prevent spyware, users
- should only download software from trusted sources.
- They should also read all disclosures when installing software, avoid clicking on pop-up ads.
- Furthermore, they should stay current with updates and patches for browser, operating system and application software.
Tips To Keep Your Computer Virus, Spyware and Hack free all The Time
Keeping your computer free from virus, spyware and hackers is a continuous process and does not really end with taking the above mentioned steps alone. Users need to have a rethink and be conversant with how information can and might be shared.
In keeping up with this, users should also learn to do the following to prevent unauthorized access to their files.
- Never give out your password. This is the number one rule.
- Constant changing of passwords is necessary to prevent theft. A password manager can be used to save such passwords, thereby giving the user the confidence to create complex passwords.
- Be suspicious of every file on the internet until it can be verified.
- Only open emails from a known source so as to prevent spyware as some spywares automatically enter the system the moment an email is opened.
- It is pertinent to use a two-factor authentication method of logging in. It requires the user entering a code sent to the user’s phone after entering the username and password. This prevents hackers taking control of your account as they do not have access to your phone number.
- Logout of every account after use.
- Make sure passwords are only entered on official websites.
- Learn to recognize fake websites.
- Encrypting your hard drive goes a long way in preventing unauthorized access.
- Backup your data frequently just in case your computer gets attacked by a virus.
- Only install trusted software.
- Install updates as soon as they are available as data theft might be as a result of lapses in software developed by a company which is fixed using updates.
In doing the above mentioned, I believe computer systems will continue to remain safe from Computer hazards.
