Besides my many previous tips on keeping your Browsers(and plug-ins like Flash), Operating Systems, Anti-Virus/Anti-Spyware, and other productivity applications here are some other things you can do to help keep yourself even more secure and less likely to be ‘compromised’. Please read my previous articles on security and follow those tips first. The things here are some ways to ‘clear/delete’ temporary files that may contain sensitive information or possible a trojan/virus that is just ‘waiting’ to launch from a temporary location.
First
Every time I close my internet browser(s) (IE, Firefox, Opera etc.) I run CCleaner. Actually I run a ‘batch file’ that runs CCleaner and clears my network cache settings too. You can, and I recommend you do, simply run CCleaner every time you shut your browser. If you would like to use/create my batch file simply copy the information between the ‘start’ and ‘end’ into a text file and rename it with a .bat extension. Example copy the file into notepad and save the file with a name of clean.txt. Then rename the file clean.bat.
For XP
Start:
"C:\Program Files\CCleaner\CCleaner.exe" /AUTO
arp -d
nbtstat -R
ipconfig /flushdns
nbtstat -RR
ipconfig /registerdns
Finish
for Window 7
Start:
"C:\Program Files (x86)\CCleaner\CCleaner.exe" /AUTO
arp -d
nbtstat -R
ipconfig /flushdns
nbtstat -RR
ipconfig /registerdns
Finish
Second
Some third-party programs can temporarily store unencrypted (plain-text) passwords or other sensitive information in memory. Because of the Windows virtual memory architecture, this information can be present in the paging file.
Although clearing the paging file is not a suitable substitute for physical security of a computer, you might want to do this to increase the security of data on a computer while Windows is not running.
1. Start Registry Editor (Regedt32.exe).
2. Change the data value of the ClearPageFileAtShutdown value in the following registry key to a value of 1:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management
If the value does not exist, add the following value:
Value Name: ClearPageFileAtShutdown
Value Type: REG_DWORD
Value: 1
This change does not take effect until you restart the computer.
Hope this helps some of you.
