Did you get forwarded to another site just before this started? Just the last day or so when loading the home page laserpointerforums.com I have been forwarded to another site and got a warning that the site had malware or was a known phishing site and it tried twice to download something but my Norton internet security stopped it.
Well I am using Chrome and it happened several times, it seems to have stopped now. I also got a strange warning when loading laserpointerforums.com that said something like "This page has scripts from an unverified source". I think it was probably just a temporary problem from one of the ads but it did try to download something that was known to be unsafe. I wish I had got a screen shot of it but I didn't think to do so at the time.
i think this is probably related to spyware on your computer or something
as far as i know the ad networks LPF uses shouldn't ever have ads like this
never seen this before and would never intentionally push that type of ad
i would try running malwarebytes again and kaspersky
also might want to try tdsskiller by kaspersky to check for rootkits like zeroaccess and necurs rootkit
I deleted the extension and closed all windows and reopened. seems to have solved it.
Going to install Malwarebytes now.
edit:
Malwarebytes got a bunch of hits and quarantined it off. But it still gave notifications of blocks.
So I ran in safe mode and deleted a bunch of dubious and adware looking files and folders in the programs folders. Seems to have solved it and no block notifications so far.:beer:
