Using OSX 10.6.8, recently been having popups, think it's adware/malware from MediaDownloader, one of the first pop ups to occur. The second pop up to occur was Trojanalert. Never had a virus on this computer. Please help remove.

First, thanks for the quick response. This is the website that I looked at and was trying to follow. There are no extensions listed in my Safari, and the only two in Chrome are: Google Docs and Java for Browsing. In Firefox the only extension is Garmin Communicator 4.1.0.

To the best of my novice ability I followed the directions to look at the libraries and have not found malicious things there either. As I cannot upgrade to 10.7, is there anything else I'm missing? Again, I've tried my best to locate the cause, but I'm new to looking at files and paths. Nothing jumps out as abnormal or as something listed on thesafemac.com/arg .

Thank you again. I downloaded and ran the tool, but it didn't pick anything up. I noticed them first pop up when I was using Shutterfly, and now they intermittently pop up. If I noticed them starting last weekend, could I just restore my computer, via Time Machine, and take care of it that way? If yes, would I lose any documents I've created between the weekend and now, or does Time Machine focus on settings only?

Otherwise, I'm guessing I should ask someone to look at it. Would you agree? Thanks for your patience, I appreciate it.

Thanks for weighing in. Below are the results:

Problem description:

I'm currently using OSX 10.6.8, 2.4GHz Intel Core 2 Duo Processor, 2 GB 667 MHz DDR2 SDRAM Memory. I am not able to upgrade the operating system, and the computer still has 67 GB of memory on the harddrive. I don't use it for anything very intense, mostly internet browsing. I was at a hotel over the weekend and connected to their free wifi. Once back home, two days later, I started receiving pop ups in Chrome (after using www.shutterfly.com). The first was MediaDownloader, so I assume that is the culprit. The second pop up to occur was Trojanalert. I looked through some online community forums and was pointed towards downloading and running AdwareMedic. My operating system does not support this program. Next I read up on how to examine libraries and extensions to find the issue. I'm not well versed in this, but I followed the directions and did not find any malicious looking extensions or items in the libraries. Before looking for the "thing" to remove, I backed up my computer as recommended.

I have never, to my knowledge, had a virus on this computer. I have never experienced pop ups, and I very rarely download any program, especially not software included with other programs.

Nothing has really helped. I tried to use Time Machine to reset my computer to a backup that existed before I started experiencing problems. However, there is not enough space on my hard drive to complete the backup. Are there certain folders or programs that I should replace with Time Machine that could take car of the problem?
