Recently my computer had been infected with malware that attempted to extort money by posting all kinds of alarmist messages on the screen, telling me that my HD overheated, sectors corrupted, etc. It removed registry entries, making it impossible to launch apps. It aslo hijacked the browser.
I managed to clear up most of its effects by restoring the original settings (system restore), then I ran: McAffee anti-virus (found a few infections), Trend Micro Homescan (found nothing), SUPERAntiSpyware (found many tracking cookies, but no viruses/trojans etc.). Finally, I ran Hijackthis, but did not see anything suspicious.
The bottom line: all tools at my disposal report a clean bill of health, but the Internet Explorer 9 starts up by itself (and restarts a short while after I kiil in through the Task Manager), occasionally an audio plays from some unknown location, and once in a while McAffee tells me that it blocked an attempt to connect to an unsecure site (never happened before).
I have Windows 7, 64 bit installed on my Dell All-in-One machine. Any advice is greatly appreciated.
Thanks,
Alex
