Since two days, Avast has been catching a virus on my PC. Happens when i try to open any site. It pops up the alert window and shows this about the virus:
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. Avast says to abort the connection, and then i cant open the site, once the connection is aborted.
Then i give up, and i do some other things on my PC. 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 Starter Edition, SuperAntispyware and Spyware Terminator.
The first time, Spyware Doctor caught trojan.downloader in Program Files\Messenger\messenger.dll file.
After that, nothing in any scans.
HiJackThis also dosent show anything suspectful.
Just ran combofix too. It deleted a file:
C:\windows\AppPatch\AcXtrnel.sdb
After running combofix, Avast had again given me the alert about virus, when i tried to browse the net again. Then after waiting for sometime again, i was able to browse the net.
Any idea whats it about?
