So yesterday I was browsing the internet, when I entered a website that I thought was safe (it was the website of a book publishing company). However, it seems that I was immediately redirected to a webpage playing music, showng a picture of The Joker from Batman with a headline that said “Hacked by Khan”. I was quite surprised and mildly shocked, but exited immediately. My McAfee virus detector then popped up, saying that it had detected a virus and that it was removed. However, after looking online I decided to download avast and run a full system check. The avast scan revealed a virus called “HTML:Defacement-N [Trj]”, which was then put in the avast virus chest.
I am the most tech-savvy person in the world, and I therefore ask: Is my computer safe now, or should I take further measures? What happens with the virus in the virus chest, and do anyone of you know any specifics on the “HTML:Defacement-N [Trj]”?
if you want a extra scanner use Malwarebytes (free or pay) it can run alongside your AV
for USB protection use free MCShield http://www.mcshield.net/ fully automatic / install and forget
What happens with the virus in the virus chest,
[b]Avast 2015: Using the Virus Chest[/b] https://www.avast.com/faq.php?article=AVKB21#artTitle
Should I delete the infected file in the virus chest, or should I just leave it?
As it is comming from the web and not your computer it is not something your computer will miss (if so you should have noticed when it was moved to quarantine) so you may delete
Files in chest can not harm your computer, i usually let them stay there for a week or two before i delete
Thanks for all the answers, however I have one last question.
When reading online, I got the impression that malware infecting your computer could quickly attach itself to other files. My answer is therefore, should I feel safe now that avast has put this infected file in the virus chest, or might there still be malware roaming free on my computer? Is the full system scan a 100 % certain, or can viruses still be hiding on the computer?
There is no such thing as 100% detection.
Think about it as a disease for humans.
First there is the disease and only than doctors can try to find a cure for it.
If you want a checkup follow the instructions in the sticky at the top of this forum.
Ok, thank you. I’m going to assume that everything is okay now, as this seems most likely.
One final question: When running the full system scan, there are always some files that can’t be scanned, and for most of them this it says that this is because the file is protected by a password or something like that. Does this pose a security threat or is this normal?
I guess I thought I wouldn’t get a 100 % answer then either. But if you recommend it I will do it. I’m not sure which pinned thread you’re refering to though. Is it this?

I’m sorry, but I’m having troubles finding the FRST.exe on my computer. I found a folder called “FRST” in Windows (C:), but it doesn’t contain FRST.exe, only subfolders called “hives”, “logs”, “Quarantine”. How do I find the FRST.exe, and when found, is it sufficient to save the notepad-document in the same folder?
Yes you’re right, it was in the download folder. I was under the impression that only pictures and documents were saved there. So can I just save the notepad file in the downloads folder, or should I make a folder for frts.exe and the notepad file to be in?
