Avast today updated its definitions and introduced a false positive that labeled legitimate, and non-malicious, sites as infected with the the HTML:Script-inf threat. This would cause pages not to load properly while Avast issued warnings. Some of the sites affected by this false positive include Wikipedia, Yahoo, PCWorld, and Youtube.

 

 

Reports indicate that the culprit are the Avast definitions numbered 110411-1. A later update, 110411-2, appears to have resolved this false positive. So if you are receiving the HTML:Script-Inf alerts, please update your Avast in order to resolve this issue.

For those who can't understand computer tech lingo or language, 'click' "Update Program" under the Maintenance tab. I am one of those who can't. :) Hope this helps, too.

I had that exact thing happen to me. I did update avast to its latest version, however when I run a scan now, it still tells me I have thousands of files infected with "HTML:Script-inf".

The current engine and definitions update on my Avast is 110413-1 and the current version of my program is 6.0.1000.

Any advice on how I could stop this from happening is greatly appreciated!

I had the same problem too, but through a little bit of googling, I found out that AVG had the same false positives some time ago. I probably wouldn't have been as paranoid if Avast servers weren't down. Sad thing is ... I ran a virus scan and moved alot of .HTML files into my virus chest, and now they are nowhere to be found. Hopefully those weren't anything of vital importance.

You checked under the Avast User Interface > Maintenance > Virus Chest?

If so and they were`t there then you may want to change the Action settings for the Real-Time Shields.
For each one you have running go to Expert Settings > Actions and change the 3 options to the type and order of your choice.

Weird, I was just browsing Tumblr (a legit blogging website that I have never had any issues with before) and when I went to click on a user's profile, Avast yelled at me, said it blocked something, and I clicked to see what it was:

"Avast saved your computer from crashing"
"you just dodged a bullet"
"you may have wondered how you ended up with a virus"

A tad contradictory, eh? lol
Doing a scan anyways

Avast are trying to help me.  I was advised to use 'combofix' and that seemed to work until I did another full scan.  The virus reappeared and the warnings continued.  I have sought help from Avast again.
