IS MY COMPUTER AFFECTED MALWARE?

A common symptom of malware infection is the home page hijacking, piracy search engines, advertising pop-ups, and system crashes.

Pembajakan Halaman Home
Home page hijacking is when malware changing the web browser home page and then lock it so it can not change it back to its original choice. Or, the home page can be changed, but additional malware to be installed shortly after we return home pages. For example, certain malware will allow us to change the home page to the URL option, but it was followed by the loss of the display screen and a great search toolbar that can not be turned off permanently.
It should be noted that there are also "Piracy" home page that was done intentionally, for example by computer suppliers, ISPs, and locked the office home page to the URL of their choice (to the company home page or support page.) Piracy like that usually we recognize and do not be classified as malware. Malware is often marked by a sudden change. We who was always able to change the home page, but suddenly can not anymore.

Hijacking Search Engine
One of the most popular forms of malware is hijacking the search engines. Suddenly we know search engines on the web browser to disappear, replaced by the search engines and foreign. Often the search engine settings no longer work or if it works, there is no option to choose a regular search engine. Another common symptom of malware is the emergence of a new toolbar that claims to provide web search services. It may appear at the top or bottom of the screen and often can not be turned off, either temporarily or permanently.

Pop-Up Ads
Pop-up ads can be a normal part of surfing the internet. However, pop-up ads that appear when the user is not actively surfing the web is not normal, nor is it a normal thing when there is so much advertising that appears to be a slow connection or computer to be silent or locked. Nor is it normal if there is a window pop-ups that fill the entire screen and can not be closed.

Scareware
Scareware is a free fraud. He is also known as "rogue scanner" or "software trickster" whose purpose is to frighten people into buying or installing. Just like the Trojans, scareware deceive the user so unwittingly install the product. Scareware do scary tactics with display screen that says your computer is attacked attacked later claimed to be the solution to that problem.
Scareware using virus alerts and false system problems. False warnings that are often very convincing and will fool most people who see it. Example scareware is SystemSecurity that scare people by showing a blue screen showing Windows crashes with a window warning that urges us to fix the problem.

System Crash
System crashes always happen though now rarely than two years ago. A lot of things done to improve the stability of Internet Explorer. Kernel32.dll errors are usually caused by graphics card drivers are very rare now.
So, how to differentiate regular crashes and crashes malware? First, malware crashes often involve unusual filenames, for example djiofg982746.dll or may refer to the modules (files) are not known. Second, malware crashes can happen when you're not doing anything. Indeed, the PC can be turned on, but said nothing.
