Get rid of a fake antivirus

Have you ever heard a fake antivirus? A fake antivirus is a program that has a look just like a real antivirus. An Example of a fake antivirus is a program named Windows Basic Antivirus. This program shows you a fake warning. The warning said that your computer was infected by viruses but actually was not. Windows Basic Antivirus is a kind of virus named Gen.variant.Zusy.905. These are the steps to get rid of it:
1. Enter Windows in save mode
2. Disable "System Restore" if  you have Windows XP/Vista/7 as an operating system
3. Clean your computer with a real antivirus
4. Repair Windows registry by making a file with notepad.
    Open your notepad then type the script below, if you've finished typing, save it as REPAIR.INF.




    HKLM, Software\CLASSES\batfile\Shell\open\command,,,"""%1""%*"
    HKLM, Software\CLASSES\comfile\Shell\open\command,,,"""%1""%*"
    HKLM, Software\CLASSES\exefile\Shell\open\command,,,"""%1""%*"
    HKLM, Software\CLASSES\piffile\Shell\open\command,,,"""%1""%*"
    HKLM, Software\CLASSES\regfile\Shell\open\command,,, "regedit.exe"%1""
    HKLM, Software\CLASSES\scrfile\Shell\open\command,,,"""%1""%*"

    HKCU, Software\Microsoft\Windows\CurrentVersion\Run, Inspector

5. Go to Folder Options. Choose option  "Show hidden files and folders", uncheck option "Hide extension for known file types", also uncheck option "Hide protected operating system files (Recommended)".

6. Delete these files made by viruses:
    a.  Protector-pma.exe (located in C:\Documents and Settings\%user%\Application Data\)
    b.  result.db (located in C:\Documents and Settings\%user%\Application Data\)
    c.  Windows Basic AntiVirus.Ink (located in C:\Documents and Settings\%user%\Desktop\)

7. Re scan with an updated real antivirus program.

Problem Steps Recorder in Windows 7

There is a such a secret feature in Windows 7. It is called PSR (Problem Steps Recorder). This feature helps you to give a program tutorial to your friends in a simple way. We don't need to use a PrintScreen to adding pictures in our tutorial presentation. These are the steps:

        Start --> Run --> type: PSR then press Enter
and then the program will be launched as you see in a picture below

Just simply click on "Start Record" button to start saving your steps and click on "Stop Record" to stop saving.

I've just revealed a great tool in Windows 7, now you can try further by yourself.

Activating Hibernate in Windows 7

With Hibernate, you can save energy of your laptop. The difference between Sleep Mode and Hibernate is that  
Sleep Mode saves files and opened documents to memory while Hibernate saves opened documents to harddisk and cuts off the electric current. With Hibernate, you don't need to reboot your laptop to back to last edited document.

These are the steps:

1.  Open Command Prompt through Administrator Privilege.
2.  Type "cmd" in Start Menu then press Ctrl + Shift + Enter
3.  Type the following instruction:  "powercfg /hibernate on"
     then press Enter.
4.  Type "exit" then press Enter to close Command Prompt.

Then You will see an option "Hibernate" in Start Menu. Good Luck !

The important commands of Windows 7

The command prompt that has been in previous versions of Windows is still with us and is not much changed from Windows Vista. The command line remains a powerful and much used feature by system administrators everywhere. Thus, the old command interpreter cmd.exe has been continued although in a slightly newer version. Several commands are now in the standard list that were formerly available only on servers. There are many commands but here are 10 very important commands you must know.

1. Driverquery

Incorrect device drivers can lead to any number of system problems. If you want to see which drivers are installed on a Windows 7 system, you can do so by running the driverquery tool. This simple command-line tool provides information about each driver that is being used. The command is:

If you need a bit more information, you can append the -v switch. Another option is to append the -si switch, which causes the tool to display signature information for the drivers. Here’s how they look:

driverquery -v
driverquery -si
2. Ping

Ping is probably the simplest of all diagnostic commands. It’s used to verify basic TCP/IP connectivity to a network host. To use it, simply enter the command, followed by the name or IP address of the host you want to test. For example:


Keep in mind that this command will work only if Internet Control Message Protocol (ICMP) traffic is allowed to pass between the two machines. If at any point a firewall is blocking ICMP traffic, the ping will fail.

3. System File Checker

Malicious software will often attempt to replace core system files with modified versions in an effort to take control of the system. The System File Checker can be used to verify the integrity of the Windows system files. If any of the files are found to be missing or corrupt, they will be replaced. You can run the System File Checker by using this command:

sfc /scannow
4. File Signature Verification 

One way to verify the integrity of a system is to make sure that all the system files are digitally signed. You can accomplish this with the File Signature Verification tool. This tool is launched from the command line but uses a GUI interface. It will tell you which system files are signed and which aren’t. As a rule, all the system files should be digitally signed, although some hardware vendors don’t sign driver files. The command used to launch the File Signature Verification tool is:

5. Nslookup

The nslookup tool can help you to verify that DNS name resolution is working correctly. When you run nslookup against a host name, the tool will show you how the name was resolved, as well as which DNS server was used during the lookup. This tool can be extremely helpful when troubleshooting problems related to legacy DNS records that still exist but that are no longer correct.

To use this tool, just enter the nslookup command, followed by the name of the host you want to resolve. For example:

6. Repair-bde

If a drive that is encrypted with BitLocker has problems, you can sometimes recover the data using a utility called repair-bde. To use this command, you will need a destination drive to which the recovered data can be written, as well as your BitLocker recovery key or recovery password. The basic syntax for this command is:

repair-bde   -rk | rp 

You must specify the source drive, the destination drive, and either the rk (recovery key) or the rp (recovery password) switch, along with the path to the recovery key or the recovery password. Here are two examples of how to use this utility:

repair-bde c: d: -rk e:\recovery.bek
repair-bde c: d: -rp 111111-111111-111111-111111-111111-111111
7. Taskkill

The taskkill command terminates a task, either by name (which is referred to as the image name) or by process ID. The syntax for this command is simple. You must follow the taskkill command with -pid (process ID) or -im (image name) and the name or process ID of the task that you want to terminate. Here are two examples of how this command works:

taskkill -pid 4104
taskkill -im iexplore.exe
8. Pathping

Ping does a good job of telling you whether two machines can communicate with one another over TCP/IP, but if a ping does fail, you won’t receive any information regarding the nature of the failure. This is where the pathping utility comes in.

Pathping is designed for environments in which one or more routers exist between hosts. It sends a series of packets to each router that’s in the path to the destination host in an effort to determine whether the router is performing slowly or dropping packets. At its simplest, the syntax for pathping is identical to that of the ping command (although there are some optional switches you can use). The command looks like this:

9. Ipconfig

The ipconfig command is used to view or modify a computer’s IP addresses. For example, if you wanted to view a Windows 7 system’s full IP configuration, you could use the following command:

ipconfig /all

Assuming that the system has acquired its IP address from a DHCP server, you can use the ipconfig command to release and then renew the IP address. Doing so involves using the following commands:

ipconfig /release
ipconfig /renew

Another handy thing you can do with ipconfig is flush the DNS resolver cache. This can be helpful when a system is resolving DNS addresses incorrectly. You can flush the DNS cache by using this command:

ipconfig /flushdns
10. Tasklist

The tasklist command is designed to provide information about the tasks that are running on a Windows 7 system. At its most basic, you can enter the following command:


The tasklist command has numerous optional switches, but there are a couple I want to mention. One is the -m switch, which causes tasklist to display all the DLL modules associated with a task. The other is the -svc switch, which lists the services that support each task. Here’s how they look:

tasklist -m
tasklist -svc

Blocking An Account Automatically

There are many ways for a crackers to break your account, such as a brute force method. In this method , a cracker tries to combine characters, letter and numbers to break your user account, or guessing various words in dictionary, or breaking your account directly through the weakness of system.
In Windows 7, There is a way to reduce an account breaking by locking the account. A locking is done automatically after user gives incorrect password for several times.
These are the steps to activate this feature:
1. Start_then type "secpol.msc" in Searching box
2. Local Security Policy Editor will be opened, go to Account Policies and choose Account Lockout Policy
3. Right click Account lockout thereshold and choose properties
4. Add amount of "invalid logon" from default 0 to higher number. If you enter "3" then the user account will be blocked after the user give a wrong password 3 times
5. OK to save change
