Since two days, Avast has been catching a virus on my PC. Happens when i try to open any site. Shows this: Malware Name: HTML:Script-inf Malware Type: Virus/Worm When that happens, it happens on every site that i try to open, not related to any particular site. Then it says to abort the connection. And then i cant open any site. Then i give up, and i do some other things on my PC. Then again after sometime, if i try to open the sites, then they open properly, without any alert. I have ran scans in safe mode(turning off system restore) with Avast, Sypware Doctor, SuperAntispyware, Spyware Terminator. The first time, Spyware Doctor caught trojan.downloader in program files\messenger in a dll file. After that, nothing. HiJackThis dosent show anything suspectful. Ran combofix too. It deleted a file: C:\windows\AppPatch\AcXtrnel.sdb After running combofix, Avast had again given me the alert. Any idea whats it about? Anupam

Avast detects but must be unable to delete / quarantine the susicious file(s) while the operating system is running. Try running the Avast boot-time scan. Open the Avast scanner interface from the desktop. Once open click on the button at the top left (it looks like an eject button) then from the menu that pops up select "Schedule Boot Time Scan" and allow it to reboot your system. The scan will take place before the OS fully loads, you will be prompted for an action when detections are made.

Okay... will try that and report back. Thanks. Anupam

I'm also interested in the solution. Trief ComboFix. Scheduled boot time scan of my "Temp Internet Files". Restarted. Experienced the problem about 20 times. Then all went fine. Don't know why its happening. Also trying the boot time scan of my windows drive (C:) now. Thanks...

I did boot time scanning with Avast. Nothing. The problem occurred again yesterday. Anupam
