The ATF Cleaner is a non-invasive program that looks for files listed as temporary files and removes them from your system. Usually temporary files are removed whenever you restart your computer but modern protocols means that this rarely happens which is why cleaners such as this are required.
Remove Temp Files And Fragments Of Unassembled Malware
There are plenty of honest and nefarious reasons why you should wish to use a cleaner to remove your temp files. The best reason to use the ATF Cleaner program is to remove parts of malware. Some websites will load malware onto your system in fragments that your virus checker cannot identify. Cleaning your temp files makes it more difficult for nefarious websites to piece together a malware program on your computer because the cleaner keeps removing its components.
Conclusion - You Are Better Off Using It Rather Than Not Using It
The ATF Cleaner is not perfect and it is not comprehensive. There are malware segments that will remain and there are temp files that will not be deleted. However it is better to use a program such as the ATF Cleaner than it is to ignore the problem and hope it goes away. Use the program in conjunction with other cleaners to be sure you are getting everything.
