My cybercafe just got infected this virus yesterday. It’s spreading from removable device users plug into my server. It’s really annoying because my computers starts to hang for 10 seconds and then it run again but very slows. All I notice is windows give notification low virtual memory, I cannot run Internet explorer (but still I can run another .exe application), and I cannot shutdown the computer. It also effect Internet connection speed, but I’m not really sure about this. When I type  in command prompt netstats -a I see a lot of established connection (maybe virus sending or downloading something).

Frustrated, I’m looking on google with keyword services303.exe but it’s refers to non computer virus. I believe this is first case of services303.exe documented. Lucky me this virus not spreading in my network so I can stop it fast before it infected others computers. I try scan my computer using malwarebytes, avira, avg, eset32/NOD and they not detects any virus *great*.

The main virus is services303.exe and it’s located in [WINDOWSDRIVE]\DOCUMENTS AND SETTINGS\[USERNAME]\APPLICATION DATA\MICROSOFT\SERVICES303.exe with attributes read only and hidden.

It’s also change your registry in:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run

It’s set to run services303.exe when computer starts and giving fake program description about Adobe speed launcher.

How To Remove Services303.exe

1. Run your computers in safe mode.

2. Open command prompt, Go to folder [WINDOWSDRIVE]\DOCUMENTS AND SETTINGS\[USERNAME]\APPLICATION DATA\MICROSOFT\ and type Attrib -s -h /S /D.

3. Once attrib process done you can see file with name services303.exe, delete it! don’t forget empty your recycle bin too.

4. Delete manually auto-start services303.exe in registry, start – run -> regedit and look on this field :

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run

5. Delete all temporary Internet and windows files. Use ATFCleaner or Ccleaner.

6. Scan whole system with updated antivirus.

Done, Your computers should back normal again. Have a nice day everyone

This is really strange case on one of my cycber cafe computer. I used ESET/NOD32 antivirus to check all computers in my networks but the result is clean. One I notice is explorer.exe and svchost.exe use to much CPU usage and Memory. I sense there is something strange because usually this computer can run faster.

After checked it with this small tools memory checker finally I found the problem, my computers infected with Conficker.B Variant, It’s really funny when commercial antivirus say my computer clean.. LOL..

The Conficker.B variant a little strange, I still can open Microsoft website. The important key to sense if your computers infected is if your computer run slow than usual. Check with that small memory tools and you may find something

How to to remove Conficker.A and Conficker.B Variant

I’m to lazy for writing manual step, because conficker has to many variant I won’t you blame me if some conficker variant manual removal won’t work for yourself. Just download this conficker removal tools and before run it make sure you’re disconnected from any local network or Internet. There is fourth (4) step you have to follow using this tools.

After you kicked out this conficker you should update your computers security!!! It’s to prevent this worm back and anoying you once again. This really happen to me when I’m to lazy for update my windows the virus back again in just 1 hours haha..

Have a nice day everyone

Reason:

This day I still need windows XP for completing my daily job, beside that I also want to try windows 7, in other side I always open minded to trust every operating source is good, that’s why I choose ubuntu as my unix family. Why Windows XP still needed this day? because some application wouldn’t run smoothly on windows 7 even with xp compability. I believe other people also has their own reason.

Partition your HDD to become 4 or more drive. Drive C and D should be in NTFS format with size minimum 30GB (Recommended 50GB), another drive is free for you to choose how you like them to be. Assuming now you have 4 drives C,D,E,F and you already have all requirements now move to next step.

1. Installing Windows XP.

Just insert your windows XP DVD/CD and it will run automatically clean install. If you don’t have DVD/CD-rom you can search on google how to install windows XP through flash-disk (you will need BIOS which can boot from flash-disk) Follow all step on installation, PLEASE INSTALL WINDOWS XP ON C DRIVE. sit back and relax until windows XP installed on your computer.

2. Installing Ubuntu.

Follow all step and read the FAQ on wubi website, PLEASE INSTALL UBUNTU ON C DRIVE. Now sit back and relax again until wubi installing ubuntu on your system.

3. Installing Windows 7.

After This step now you have dual-boot it was windows XP and ubuntu. Now the last step is installing windows 7. Use DVD-rom if you have, if you don’t you can use flash-disk and created boot flash-disk using Windows 7 USB/DVD tool

Squid is a caching proxy server that can help reduce internet bandwidth usage and improving response time of loading a website by caching and re-using frequently opened web page. Squid reduce the bandwidth usage and accelerate the website loading by caching static website objects such as images, flash objects and text files, with some modification Squid can cache larger files such as PDF, MP3, executable, flash videos, etc.

Last week ago my client ask me to install squid on his computers. First time I meet problem because I’m not familiar with windows 7 (XP Still the best for me). The mostly problem I meet is I can’t install squid as windows 7 service. Anyway I finally found the way to do this… Want to know? keep reading this tutorial…

Preparation before you install squid:

1. Squid 2.7
2. Squid.conf sample

The step to install squid on windows 7:

1. Extract squid 7 and put it on example “c:\squid“.

2. Get squid.conf sample and save it as “squid.conf” put this files on example “c:\squid\etc“

3. Now the important step! we have to disable UAC (User Account Control) if we didn’t disable this we will got problem on installing squid as windows service. Mostly a lot of  people try to install squid on windows 7 has problem on this step.

Control Panel -> System and Security -> Change User Account Control Settings

Slide the bar into “Never Notify” You need to restart your computer after doing this step.

4. Open command prompt. Then install squid service by typing “squid -i” in your command prompt. If you success you will see something like this:

5. Build your squid cache by typing “squid -z” You will see this message “Creating Swap Directories” in your command prompt, just waiting until it finished.

6. After squid service installed and squid cache finish building now you have to start this service.

Control Panel -> Administrative Tools -> Services

Look for service with name “squid” the start this service (you can also configure it too to auto start each time your computer on)

7. Make sure squid process is running on your computer background. You can see this on task manager in services tab.

8. It’s might important and secure to re-enable back again User Account Control Settings.

9. You just finished installing squid, congratulation

Now you have to configure your web browser to use this squid. Open your web browser and looking for (mostly network) then write your squid IP and squid Port. Example my squid IP server is 192.168.1.254 and port 3128.

That’s it, another web browser will have almost same configuration like this. Have a nice day
