Hi - my computer seem to be infected with some sort of trojan dialer virus. AVG pop ups tell me the problem is either in C\Windows\Temp or C\Documents and settings\user\local settings\temporary internet files\content.IE5.
I tried following the directory and deleting the offending files such as win13tmp.exe but they keep reappearing. Yesterday I was unable to use Internet Explorer and access Windows Explorer - I booted up in Safe Mode and ran Adaware and SpybotSD, which seemed to have solved the problem but the AVG pop ups are still appearing today and the wintmp.exe files are still there.
Here is my HiJack This log:
