I bet you have a sneaking suspicion that the expensive MacBook or Windows laptop you recently purchased already has malware on it, right?

You know your PC has malware, spyware or adware when its performance is degraded and you start seeing popups and other odd/malicious behavior that can quickly wreak havoc on your PC.

Before you know it, sensitive and valuable information like passwords for bank accounts or e-mail accounts are stolen from your computer and whisked off to some remote hacker thousands of miles away.

Now the first thing you want to do is scan your PC or MacBook for malware before more damage is done.

I have just the free malware tool to scan your computer for various kinds of malware and adware and remove them.

Malwarebytes – Free Tool

Security software vendor Malwarebytes offers a free Anti-Malware scanner that’s designed to detect and remove worms, Trojans, rootkits, rogues, spyware, and other dangerous malware from your PC.

The good thing is that not only Malwarebytes Anti-Malware scanner is free but it’s available for both Windows and Mac.

The scanner works with Windows 8.1, Windows 8, Windows 7, Windows Vista (32-bit, 64-bit) and Windows XP (32-bit).

On the Mac side, Malwarebytes Anti-Malware works on iMac, MacMinis ands MacBooks running Mac OS X 10.7 or higher operating system.

I downloaded the Anti-Malware scanner tool and tested it on my iMac. The scan was extremely fast and took just a few seconds. Fortunately, the scan reported no malware on my Mac.

You can download the Malwarebytes free scanning tool for the Mac on the security firm’s web site.

If you have a Windows desktop or laptop, download the Windows version of the free Malwarebytes Anti-Malware scanner.

Important: One thing the free Anti-Malware scanner will not do is offer real-time protection. You can use it only to remove malware.

If you want a real-time scanner that automatically prevents malware and websites from infecting your PC, then you must fork out $25 per year (three PCs) for the premium version of the Malwarebytes scanner.

Windows users can also get the Anti-Exploit software as a free download.

Malwarebytes Anti-Exploit is said to wrap four layers of security around popular browsers like Internet Explorer, Mozilla Firefox, Google Chrome and Opera, preventing exploits from compromising vulnerable code in the PC.
