Security Issues Found in Lenovo PCs

May 21, 2016 by computerera


Bloatware is what companies are adding to the devices unpacked. Though it may promote the company’s useless applications that are purposelessly installed by default. The bloatware not only eat the memory on the device but also brings vulnerabilities along with them as per the observation kept on Lenovo PCs causing security issues.

The Lenovo computers that are shipped in between the years 2014 and 2015 have exposed a log of non-identifiable Pc information to the Lenovo resulting in the installing of OneKey Optimizer bloatware on the laptops in their first connection to the internet itself. There also found some other vulnerabilities that tend PC to clean install the OS with their malware activity.

The online security of Lenovo laptops has remained a question with the inclusion of unnecessary software on the computers. Many security issues of such behaviours that are found later didn’t follow the guidelines of anti-theft software.

Since the security systems are expelling the Lenovo’s bloatware and other suspicious behaviours of the computer, the company have stopped producing the machines like Service Engines for enterprises.

We have already seen a malware called Superfish Visual Discovery, a browser extension that recommends the cheaper alternatives to the product images on the webpage. it might sound useful but annoying when it overtakes the browser expereince.

Windows 8 operating system is some what constant in resisting these malware behaviours with its built-in Platform Binary Table feature.

However, if you using the Windows operating system that is lower than Windows 8, you should be aware of the unknown activity on the system. Think a while before buying the Lenovo computers.

How to Make Windows More Secured Without Antivirus

April 17, 2016 by computerera

No matter what version of Windows operating system are you using, your computer is not fully safe from viruses. Even the top most antivirus software cannot provide the 100% security to a computer. There is still a way to make Windows more secured without an antivirus installed on it.

This tutorial will help you take control of the whole computer as an administrator and disallow the users to make any changes to the existed programs or install new ones.

1. If any virus or malware program installs on the computer, it would have happened due to the other users’ unconscious actions or clicks on the relevant harmful links on the web or on the installer packages. ‘Windows Installer’ program is the program responsible for the installation of any software program on your Window Computer. If we can restrict users from accessing it, we could take the better control of the computer.

* To perform the operations in the following procedure, you need the administrator privileges on your computer.   

Click Start button > type ‘edit group policy’ (without quotes).

Open ‘Edit Group Policy’ windows and navigate to the following path, Local Computer Policy > Computer Configuration > Administrative Templates > Windows Components > Windows Installer.

Find the ‘Turn off Windows Installer‘ option and double-click on it. It will open up with a default option ‘Not configured’ selected. Change it to ‘Enabled‘ and select ‘Always‘ under Disable Windows Installer options. Click ‘Apply‘ and ‘Ok‘.

This will restrict the users on your computer make changes to your already installed programs and prevent them from adding new programs.

2. Blocking Windows Installer alone is not enough to make Windows more secured. Make sure you have your ‘Firewall’ enabled always. Disable the ‘auto-run’ for all removable media. Malware will not exploit sometimes unless the auto-run is executed.

3. It is always better to monitor the users activity. We can restrict the software usage for users without the administrator’s authorization. To disable the access to all software programs to users on your computer, go to Local Computer Policy > Computer Configuration > Windows Settings > Security Settings > Security Levels. Double-click on the ‘Disallowed‘ setting and ‘Set as Default‘.

4. Windows computer comes with ‘Windows Defender’, the best and native anti-malware program installed on the computer. Make this program run under ‘Normal Priority‘ tasks. To set so, go to Local Computer Policy > Computer Configuration > Administrative Templates > Windows Components >Windows Defender.

Double-click on ‘Allow anti-malware service to start-up with normal priority‘ and set it to ‘Enabled‘.

Make sure to update the virus definitions of the Windows Defender from time to time. Only maintain one Administrator account to avoid diluting the security. This will take care of the most of the cases of security on your computer and make windows more secured.

What is the reason behind stopping the support for Windows?

There is no big reason behind the decision of Apple. The Windows OS has evolved into powerful and independent operating system and has more better runtime options. So, Apple has thought of ending support instead of working on it just for the sake of few applications.

The recent Zero Day Initiative studies about the recently detected vulnerabilities of Quick Time player, moov Atom heap Correction and Atom Processing Heap Correction which add up to the Apple’s depreciation news and stresses the security of the applications that are using Quick Time player.

Though there found no active attacks with these vulnerabilities so far as per Trend Micro, the better way yet to keep your computer and data on it safe is to uninstall Quick Time on Windows.

Are application using Quick Time are vulnerable too?

Yes! If the supportive plugin is vulnerable, the application using it will also be not safe. If you are aware of the sudden depreciation of adobe flash player; the applications using adobe flash player went void and stopped serving within short period of its dismissal. The same situation the Quick Time Windows is in, now.

How to check and uninstall Quick Time Windows?

You might have installed Quick Time knowingly or unknowingly on your Windows computer. You can uninstall it from Control Panel > Programs > Uninstall a Program > Search for ‘Quick Time’ > Click ‘Uninstall’.

Do not risk with your sensitive data on the computer. Outdated software is an open door for hackers. Stay safe.
