I have been getting a warning from my Avast several times tonight that it has blocked a potential threat. When I click on the more details link this is what I get: URL hxxp://18.104.22.168/ad/l/1?s=b008&n=10886%3B10886%3B87146%3B91559%3B93644%3B94047%3B376342%3B377624%3B379152&t=1402806877145374010&f=&cn=slotEnd&et=I&tpos=3&init=1&slid=1 Infection URL:Mal It is blocking the threat, but I think I may still have malware, so I ran scans and am attaching them. Have not done anything unusual on my computer the last couple days, except that a couple days ago Avast told me it noticed an add-on with a poor reputation, and asked if I wanted to remove it. It was the Ask toolbar. After I agreed to remove it Avast said I needed to select my new homepage. My homepage is usually Google, but Avast only gives me the option of Yahoo or Microsft Bing. I clicked on Bing, but my homepage is now MSN. Last week when trying to organize some pictures for my son's senior recital I was downloading/updating Picasa and I think that's where I got the Ask toolbar. I was not paying very close attention obviously since I am usually more careful about foistware on my laptop. Otherwise I have not done anything unusual on my computer this week that I can recall.
