Free Advice For Priceless Security

Potential Threat: One of the techniques that hackers use to infiltrate operating systems is known as polymeric downloaders. These are viruses that could download other, more complex viruses, password stealers or remote controlled software. These downloaders typically access systems via emails or zip files. They can also get to your computer in tandem with other programs, mostly together with free game downloads or with illegal software. These downloaders can also traverse when connecting infected USB disks to your computer. Virus authors aim to trick you into executing these downloaders. These tricks could be sophisticated, which sometimes could confuse even sophisticated computer users into executing the underlying viruses and infecting their systems. A more complex infecting technique is called polymorphic downloaders or polymorphic viruses, which allows viruses to traverse undetected.

Polymorphic downloaders have ability to change their form every time they infect host systems. Advanced infection techniques allow hackers to divide the virus body in ever-changing code fragments which are implanted in what are called code caves. The actual virus functionality gets reassembled only during the point of execution. This allows polymorphic viruses to exist while avoiding detection by certain pattern based virus detection software programs. Such viruses only can be detected using behavior detection techniques. 

Here are some free tools that could be used to scan your computer for potential infections:
