Unfortunately, you can no longer ignore viruses on the internet. Your computer is attacked by various types of adware, tracking cookies, spyware, malware, worms, and Trojan Horses. What do these programs do and how do you protect your computer against them? Most viruses on the Internet are written for Windows computers. If you have an Apple operating program or a Linux operating program running, you will therefore be less affected by viruses.
Prevent and remove viruses
Make sure you have a good virus scanner
There are paid virus scanners and free versions. You can’t live without it. Well-paid virus scanners are Bitdefender Antivirus Plus and Kaspersky Antivirus. There are also free virus scanners that do their job properly. Examples include Avast Antivirus and AVG Antivirus.
Check your list of programs regularly
Is there a program you are not familiar with? Google the name of this program. There is a good chance that it is an unwanted program. If you have indeed found on the internet that you have an unwanted program on your computer, you will usually also see tips to remove this program.
Clean your computer regularly
You can use the CCleaner program for this, for example, and have your virus scanner perform an extensive scan of your computer every month. If your computer suddenly slows down, your start-up page suddenly changes or if pop-ups appear constantly in your browser, there is a good chance that your computer has acquired a virus. In that case, install a virus removal program on your computer. Examples include Spybot-Search&Destroy, Spyhunter, and Malwarebytes Anti-Malware.
Tired of pop-up windows on the internet?
Never close these with cancel or the cross, but use Alt-F4 for this. When you cancel or use the cross, you may inadvertently get adware on your computer.
