From the avast forum
this false positive will be corrected in new vps update in about 30 minutes. We are blocking ads from yieldmanager.com (by mistake because they were in our stats as distributor of Fake Antivirus websites).
Thank you for information you have provided.
Sine he posted that, there HAS been a new defs update so I would suggest updating again and see if the detection is gone.
My Avast AV program detected, this morning, the following trojan when I went to my home page (Yahoo Weather):
JS: ScriptIP-inf [Trj]
Action recommended was to 'abort connection' which I did. I tried to access Yahoo home page and got the same alert. It allowed email access but with an Avast pop-up message that Avast has blocked access to ad-yieldmanager.
I was not sure how to report this information to Yahoo itself other than to use their 'feedback' option.
Since I use Yahoo mail, I am unsure what consequences will happen if I try to read or send emails. I can see that the infection is connected with Java Scrip, but unsure how safe it is to try to use my email at the moment.
Is there any information about this trojan and/or have others reported similar problems with Yahoo today?
