I use XP Pro SP3. While working with files I got a message that Internet Explorer detected some harmful files and wanted to scan my pc with PCPrivacyCleaner. I told it not to install, since I did not trust the message. But, it started installing anyhow and got stuck in a loop. Now my PC keeps rebooting when it loads the desktop icons. I tried using safe mode, but none of the options offered will work. They keep rebooting also. I get the same results with using the last properly working option. It has to be the software that tried to install, since all was fine until that happened. I thought using safe mode would allow me to delete what was installed and all would be fine. I ran SpyBot S&D, Ad-Aware, CCleaner and AVG Anti-Virus and all was fine, earlier in the day. I had no problems until the Internet Explorer message appeared. I am desperate for a solution and would appreciate any suggestions. I searched your site for common problems, but nothing seemed to help. Thanks in advance. Sorry for the lenghty explaination, but I wanted to be as accurate as possible.
