Double Up Your Computer Security - Free Online Spyware/Virus Scanners

The one thing we know for sure about today’s malware is; it’s very smart! It’s so smart that it often recreates its own component parts even if it has been deleted. How smart is that?

Today’s malware can write itself into multiple parts of the operating system and in many cases it can hide it’s files, registry entries, running process and services, making the infection virtually invisible.

Highly experienced computer users’ have come to realize that the Internet is alive with predators intent on installing damaging programs, (Spyware, adware, viruses and Trojans), on vulnerable computer systems.

However, the sad reality is, the majority of computer users are undereducated when it comes to recognizing the dangers and threats that the Internet poses to their computers, and to their personal privacy.

The installation of such malware invariable leads to a critically disabled PC, or in the worst case scenario, allows hackers access to important personal and financial information.

There are plenty of good anti-malware products, but no one anti-malware tool is likely to identify and remove all of the millions of rogue malware that infest the Cyber World.
