I was running a “Thorough” scan on my computer and allowed it to search archive files in the scan.The scan found a trojan horse on my computer. The malware name is “Win32:BredoLab-k [Trj]“. The pathname of the file was “C:\Documents and Settings\Local Settings\Application Data\Microsoft\Outlook\Outlook.pst\Personal Folders\Top of Personal Folders\Inbox\Shipping Confirmation for Order – (random series of numbers)\(random series of numbers).zip\(random series of numbers).exe”. When Avast found the virus, it recommended that I move it to the “Virus Chest”. When I selected that option, I got a message that said: “Error occurred during moving file to chest: The operation is not supported for this type of archive.” I next tried to repair it. I got a message that said “Error occurred during repair…” blah blah blah. I next tried to delete it. I got the same message. So now, I don’t know how to get rid of it.
I suspect that what Avast is picking up is a virus from a SPAM e-mail (one of those e-mails where they pretend that they’re sending you confirmation that a UPS/FedEx/DHL package has arrived and they tell you to open the attachment to view a receipt or something like that). I’ve never opened one of those attachments and I never open those e-mails. However, sometimes when those e-mails go to my inbox instead of my junk e-mail folder, I have to right-click on them in order to send them to the junk e-mail folder. Unfortunately, when I right-click on the e-mail it still ends up opening the e-mail in the preview pane. I don’t know if doing this can still expose my computer to a virus, but if it does let me know.
Anyway, the reason I suspect (again, SUSPECT but don’t know for sure) that the trojan horse Avast detected is from an e-mail is because the location of the trojan is in a Outlook .pst file. .pst files are usually backup files that Outlook creates for my e-mails. If a SPAM e-mail that was sent to me had a virus attached, even though I did not open the virus, it’s still on my computer because Outlook made a backup of the e-mail that it was sent in. So… if Avast can’t access the trojan and remove it, should I just delete the “Outlook.pst” file?
A Trojan virus is faulty computer program that can infect remote computers by changing the desktop or deleting important files. Generally called a Trojan Horse, it appears as a legitimate file or software from a trusted source, therefore tricking users into opening it or downloading it. Take action and protect your personal computer files by learning to delete this Trojan virus.
