Security Questions
- Is it safe to use Ultrasurf to visit any websites? Can third party monitor what websites are being opened?
ANSWER: Ultrasurf uses industry standard strong end-to-end encryption to protect your data transfer from being seen by third party.
- If I use Ultrasurf to post on forums or visit websites, does the forum or website know my real IP?
ANSWER: Ultrasurf uses proxy technology to hide your IP address from websites you visit.
- After using Ultrasurf, are there any web history records on my computer?
ANSWER: By default, after you quit Ultrasurf, your browsing history will be automatically cleared. This option can be turned off.

If Ultrasurf is not shutdown normally (for example, your computer suddenly loses power, etc), you may need to restart Ultrasurf and quit normally.
- Is Ultrasurf a Trojan or virus?
ANSWER: Neither. Some anti-virus software companies misclassify Ultrasurf as a malware or Trojan because Ultrasurf encrypts the communications and circumvents internet censorship. We are in the process of resolving this issue with these anti-virus companies. It is our mission to protect users' privacy when browsing the internet.
