5 Tips To Delete traces left on a Computer

Privacy is an issue that is not taken seriously enough.Today, using the right tools, anyone can get into your computer, know what you’ve been doing in the last few hours and use that information against you. Here are 5 tips to leave no trace on a computer after use:

1) DNS Cache – Internet Pages
Each time you load a webpage in your browser, Windows passes the request to a DNS server to translate the domain name to an IP address. To save time, the system uses cache separately. It goes without saying that this information can be easily removed.

If someone opens the DNS cache, for example, using DNSDataView, you know what pages you visit most often. To delete them, you can use the same utility or enter ipconfig / flushdns in the command line. CCleaner can also do this from the section of the system (DNS cache), but the box is unchecked by default.

2. Drives – USB Flash Drives and Connected Devices

Each time you connect a disk to a Windows PC, its identifier is stored in the Windows registry. So you can get information like serial number, make, model and when the device was last modified.

To remove these tracks, you can use USBOblivion, a portable tool that scans the registry of the identifiers of removable storage devices and removes them.

3. Flash and Java cache

Web browsers cache is limited to web pages and images. Web applications created with Flash and Java are not affected by cleaning the cache, because the files are stored in the cache plugins. CCleaner can remove both, but if you prefer to have more control over what they have to erase each time. In Flash, go to Control Panel and check the contents.

For Java, follow these simple steps, from Oracle. To prevent the contents of Java they are temporarily stored on your computer, clear the settings in temporary files.

4. File (pagefile.sys)

The paging file, also known as swap or swap file, is used as virtual memory on the PC, when there is not enough RAM for some tasks. As a result, sensitive data is exchanged. In this article, Microsoft explains how to clean the file Pagefile.sys every time you logout.

You must open the Registry Editor (regedit.exe) and change the value of this key ClearPageFileAtShutdown:
HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Control Session Manager Memory Management

REG_DWORD value should be 1. So you can be sure that no passwords or other data on the exchange.

5. Remove Metadata

Metadata is the ID of a file. They may contain information about the author, when the document was created or where the editing took place. It is useful for some, but dangerous for others to use that information.

To use this we us the tool Metastripper, which is very effective to remove a file metadata
