Hi,

I'm very happy with your performance. I'll be a customer for life. Winctrl32.dll has gone. I have 4 other Bought and Paid for Malware programs that I have but none are as good as yours and none have the same individual response times as good as yours. Some do not respond to help At All.

Great job!

Rootkit

A rootkit is a set of programs used by a hacker to conceal unauthorized access to a computer. To bypass antivirus scans, a rootkit replaces Windows system files or libraries, or installs special software modules. The hacker installs the rootkit after obtaining user-level access, typically by cracking a user’s password or exploiting a vulnerability of the operating system. The rootkit proceeds to gather other user IDs stored on the computer until the hacker gains administrator access to the system.
Hackers commonly use rootkits as a technique for concealing trojan activity.

Be Aware of the Following Rootkit Threats:

Abwiz.F, CDiskDun, Pandex, pe386, Win32.Agent.dp.

Downloading and Installing Freeware or Shareware

Small-charge or free software applications may come bundled with spyware, adware, or programs like Agent.C. Sometimes adware is attached to free software to enable the developers to cover the overhead involved in created the software. Spyware frequently piggybacks on free software into your computer to damage it and steal valuable private information.
