Remove Viruses without installing any virus-scanner
Think a situation where your computer is very badly affected with the virus and your virus-scanning software is not doing anything, what you will do in such situation?
Engineers format their Windows in such situation. But there is another way also. Just download a superdat file from McAfee website. You have to extract the content of the dat file then run the executable files in command prompt.
Just go to Direct link
Create a new folder in c:
Rename it to scan
Place the SuperDat file into c:\scan folder
Click on Start > Run > cmd
Press enter it will open command prompt
Type there following command:
cd c:\scan
sdatXXX.exe /Ewait for a 2 minutes then run the following command
scan /ADL /ALL /SUB /CLEAN /REPORT C:\scan\virus.txt
This command will scan all drives and subdirectories and clean the infected file and also generate the report and save it in virus.txt file.
P.S. The SuperDat file generated on each day, so please download it on the day of virus scanning.
For better result do this procedure in Windows safe mode.

Password Protecting USB Pen Drive
One of my user needs to create a password protected folder in its pen drive. This is very simple but one more special requirement he asked for, if he insert that pen drive in any another pc he can able to see that folder over there without any software installation. This is quite tricky requirement. I found a tool for it i.e. Rohos Mini Drive. It’s a freeware with some limitations.
Rohos Mini Drive creates hidden and encrypted partition on the USB flash drive memory. You work with the files on the hidden partition without opening a special program. Those who have megabytes of sensitive files on the USB drive and seriously concerned with a data security, cannot imagine their USB stick without the hidden volume that is created using this tool.
Download the program from here. Install it and run it.
After installation the Rohos Mini Drive, insert your USB pen drive to the computer and run the Rohos Mini Drive application. Click on Setup USB Key
Insert a password.
It will create a partition namely K: with 297mb space. You can customize the partition size by clicking Change button.
Just you have to add file in this newly created partition, when you done just eject that partion as well as the pen drive.
For testing purpose you can insert this pen drive to any another PC. There it will show you one roho_mini_pendrive icon. Double click it and insert your password that’s it now you can access your password protected partition on that computer.
