How to remove old software that makes your PC Vulnerable
What are software vulnerabilities?
A software vulnerability is a weakness found in a piece of software ( app ) or in an operating system that can cause security issues.
In order to take advantage of this flaw to infiltrate your PC, an attacker will have to gain access to the flaw and have the capability to exploit it. An example of a software vulnerability is buffer overflow.
This is a very common weakness, where a data input uses up more space than it’s given, so it spills over into different locations, causing an app to crash or giving cyber attackers a way into your PC. Buffer overflow is also a method that cybercriminals can use to gain administrator right to your system. Once that happens, they can run malware on your PC without you knowing it.
Uninstall unused apps
In Windows, go to Control Panel -> Uninstall or Change a Program and click on the “Installed on” column to sort your apps. This will help you see which are the oldest apps you have installed and sort through them so you can delete what you don’t use constantly.
Check your browser plugins
Browser plugins are an insidious security threat. They seem completely harmless, but the truth is that they can hurt both your privacy and your security.
Delete software installers
Once you’ve used them, there’s no reason to keep them on your PC. If you have them at hand, you may be tempted to install older versions of software, which may be flawed and, consequently, vulnerable.
Also, be very careful where you choose to download software from. Not all download portals are trustworthy and the installers you get from them are sometimes filled with bloatware (or crapware), such as toolbars and other add-ons. The best is to go directly to the software maker’s website and get the installer from there. You can make sure you’re getting the latest version, that the download is secure and that there’s no bloatware involved.
