How To Stop Viruses, Trojan and Malware

How to remove or detect a keylogger? If you suspect someone stole your password, chances are, it could be your girlfriend or boyfriend that installed a Keylogger, also known as a rootkit virus. Keyloggers are legal when used according to the law for monitoring your underage children, however, such tools can be abused for sinister use such as stealing Hotmail and Gmail password, not to mention stealing credit card information.

What is a rootkit virus? A rootkit for Windows systems is a program that penetrates into the system and intercepts the system functions ( Windows API ). It can effectively hide its presence by intercepting and modifying low-level API functions. Moreover it can hide the presence of particular processes, folders, files and registry keys. Some rootkits install their own drivers and services in the system (they also remain “invisible”).

Most anti keylogger software are designed to scramble keyboard keystrokes, they are not designed to detect and remove these keylogger software from the system, especially those keyloggers that are deeply rooted into the Microsoft Windows Root system.

More often than not, keyloggers are known as a very tough to remove spyware computer surveillance software once it is rooted into the system, sometimes they can automatically insert themselves into your antivirus’ whitelist, thus making your antivirus ignore them. You can try these alternatives.

Conclusion

Take caution when opening attachments: Keyloggers can be present in files received through email, chats, P2P networks, text messages or even social networks. If someone sends you an email out of the cold or the contents of the email are asking for your personal information, chances are there’s a keylogger in there somewhere.

How to remove rootkit virus? Where to download free rootkit detection and removal software? A rootkit virus, trojan, spyware and worm is a malware program that has administrator level access to all the network systems. What it does is it burrows itself deep into the system and hides itself, making it almost invisible and hard to be removed and detected by antivirus.

Usually rootkit malware monitor traffic, keystroke and allow backdoor access for spreading viruses and trojans, some even turn your computer into a botnet – a term known as sending out spam mail via your computer without you ever knowing.

It is hard for normal antivirus to detect their presence because rootkit tends to boot up along with windows before the antivirus is booted up. Most antivirus now comes with rootkit detector and detection ability, not to mention the ability to remove these rootkits, however, if the rootkit malware is present prior to the installation of the new antivirus, then it is not possible for the antivirus to detect it.
