2. The viewurl interface is open。
Click on the display information button to see traces of computer usage。
Of these, http displays web browsing information; file displays file opening records; others is other records such as windows. (it's really powerful, and about half a month ago i found out all about my classmates' journal. Amazing
(ii) installation of eraser
1. Double-click the eraser installation icon in the folder。
Access installation wizard, click on next
Choose “i accept the agreement” (by default, “i reject the agreement”) and then click on next。
Enter the installation directory and select the installation directory. The default is installed on drive c. Keep clicking on next。
5. Select the start menu file and continue to click on next。
6. Choose whether to create an icon on the desktop or to create a shortcut menu。
7. Commence preparation for installation. Click install (installation)。
8. Information
9. Achieved。
Use
(i) viewurl
1. The interface is visible when the icon is opened. The use of viewurl is detailed in the previous installation section。
2. Use the trace clean-up function of 360 security guards in 7. 5 to see if the records extracted by viewurl can be erased. First, open the security guard and choose to clean the tracks。
Click to start scanning. Security guards automatically scan. The interface is as follows。
Click to clean up immediately。
5. At this point, viewurl is opened. Signs of internet access were found to exist, but files opened records that could be erased. When you open the document under the start menu, you find the document empty. The clean-up function of note 360 is valid for emptying the records of the document。
As a result, the clean-up footprint of 360 security guards had little effect on viewurl. Viewurl can still dig up a lot of information. However, when you open the documents under the start menu at this time, you find that all the files open are missing. Note 360 security guards are still effective in eliminating windows’ own document recording functions (i'm sorry, teacher, if there is a blank in the document, the chart cannot be cut off and jumps back to the desktop. So you open a map of the desktop, right-click it and delete it, so you can fix it。
(ii) eraser
1. Eraser's icon will be displayed on the desktop after installation。
2. Click the icon to open. The interface is as follows:
3. Selection menu. Windows, for example, selects the files that you want to erase, as necessary, such as open history, running record under the start menu document. (this is good, if there are no traces on the internet or records of opening documents, it is easy to draw the attention of supervisors, and an arbitrary choice can be avoided
4. Web page views (including most recent c)It is also possible, of course, to make changes at its own request. Including microsoft's internet explorer & msn, fire fox, google, opera, etc。
5. Plugin cleaning
6. Document shredding
7. Clearing excess space
8. Log
9. Commencement of removal
At the end of the meeting, the interface was as follows:
10. Clearing of disc c. (in the course of the experiment, it appeared that there was no way to “counter” viewurl if the excess space in the c disk was not removed。
11. Computer restart. This step is particularly important, and if the software is not restarted, the re-opening of viewurl will reveal that traces were not cleared. After restarting, viewurl was opened and all traces of computer usage were found to have disappeared. The document opening information in the same start menu also disappears。
Thus, eraser's function is more than 360 security guards ' ability to clean traces。
Problems encountered and perceptions
The biggest problem encountered in the application was that, after the first use of eraser, traces were found or not erased after the first use of viewurl, which i thought was different, and went online and found that after the use of eraser, the common viewurl had no way of rediscovering it (source: http://lain. Mpc/post/55. HTML (http: \/lain. Mpc \/ post \ 55. HTML)). So the solution was found because the eraser was used from a website abroad, and the software version was also available in english, and the chinese interface and the english interface were different, so it was particularly difficult to find the right solution, and it took only a long time to try again. After the experiment succeeded, it found that it had failed: first, it had not cleaned up its c disc; second, the computer had to be restarted。
Eraser has the option to choose the part of the computer that he wants to clean up in the course of its use, thus avoiding the deletion of all computer usage records, which, once deleted, can easily draw the attention of supervisors, which eraser can avoid, one of its advantages. Second, eraser is much more powerful than the same type of eraser software (e. G. 360), so when selecting eraser, we try to avoid being found; and, of course, in order to avoid the illegal or unauthorized use of our pc machine, we also need to find more effective “excavation software” against eraser, ensuring that it is better than viewurl。
V. Videos and notes
The video was produced in two parts。
Part i: (video insertion)
Step 1: installation and use of viewurl
Part ii: installation of eraser
Step 3: clean-up with 360 security guards to clean traces
Step 4: reuse viewurl after liquidation to see if information can be extracted
Step five: use eraser for clean-up. This is a time when it has to be restarted to be effective。
Part ii: (as the computer is restarted, it is necessary to turn on screen video experts once again, which is why a record appears later in the viewurl interface, so do not think that the experiment has failed) (video insert)
Step 1: open documents under the start menu to see if there are computer usage records
Step 2: open viewurl and dig again the computer log. As a result, all computer usage records prior to restart were found to have disappeared。
