The increased use of computers has also increased the risk of highly damaging cyber attacks. Having a burly defence mechanism that can eliminate all types of bugs and viruses has become a need. Read on!
Every time you go online, your computer is highly vulnerable to malicious malware infections, viruses and spyware. Most viruses are extremely dangerous and spread very swiftly to destroy and change data on your computer. This is why it is important to prevent a virus from entering your system, or control spread in case one has already gained entry!
Even though complete abolition of a virus infection can never be guaranteed, still keeping your computer secured with a reliable defence mechanism will always trim down the threat level.
Here are some steps you can take to secure your computer from viruses:
Choose the Right Operating System
Keep the level of security and vulnerability in mind while choosing an operating system for your computer. Check if it allows limited user accounts, uses all file permissions and above all, can be updated on regular basis. For example, Linux has no identified active viruses and bugs till now.
When you have begun to use an operating system, keep updating it with security updates. It remains equally important to update other software on your system too.
Install a Good Antivirus Program
Installing a reliable antivirus program and keeping it updated is probably the most effective way of defending your computer from viruses. When a virus tries to get into your operating system, files or email, your antivirus program will scan for it.
Develop a habit of checking the website of your antivirus manufacturer quite frequently for updates, for new viruses can emerge each day. Where some antivirus programs come with annual subscriptions, numerous others are available for free. AVG and Avast are fine and reliable free antivirus editions.
Beware of Emails from Unfamiliar Senders
Avoid opening mails from strange senders and checking any unrecognizable email attachments. Most viruses attached to emails spread and do the damage as soon as you open them. You can take help from Microsoft Outlook when you have to block dangerous emails messages or attachments.
Give Importance to Physical Security
You can set a BIOS password for preventing access to your system as well as removable devices such as USB. Avoid using external hard drive or USB devices for the storage of important data. You can also use a Kensington lock to prevent unauthorized access.
Encryption with a tool like Truecrypt can be another effective way because:
- It works on everything from Windows and Linux to OS X
- You can encrypt all your user accounts rather than only a few files
- The system will always ask for password to login
Installing a Firewall
Installing a software firewall is another effective way to keep your computer protected. A good firewall program will alert you to all the activities that are suspicious, especially when a virus tries to connect to your system. It will also prevent hackers from downloading potentially damaging programs to your system.
