Hello! I keep getting a message from Avast! saying that it has blocked Win32:Small-NNE [Trj] and I was wondering where this virus is coming from and how can I keep it from popping up. Is it coming from a specific website that I’m visiting? Why does it pop up immediately when I open up Firefox? I know Avast! is blocking it but it’s making me a bit nervous. 
By the way, I did a full scan with Avast!, MalwareBytes, and Spybot Search and Destroy and everything came up clean.
did you update Malwarebytes before you did the quick scan ?
follow this guide and attach OTL and aswMBR logs

Hello,
maybe similar to this: https://forum.avast.com/index.php?topic=103154.0
Panda updates his antispam and there are some non-crypted URL signatures.
Milos
i guess we see if panda is installed from the OTL log ?
Hope I did this correctly!
Pondus, I don’t have Panda antivirus but I did the rest of what you asked and attached to results in the above post. I hope this helps you! 
you did not attach OTL log … but i think this is your problem http://forum.avast.com/index.php?topic=103158.0
Aw, I knew I’d screw something up. Sorry.
So, with respect to that thread, will this pop up just go away eventually or should I just keep ignoring it?
do you have this program installed see picture in reply #2 http://forum.avast.com/index.php?topic=103160.0
I’m so sorry, I don’t see the picture of the program (me=numbskull), what is the program called?
hxxp://software.visicommedia.com/en/products/antiphishing (replace xx with tt) contains a link to test if your pc has visicommedia_antiphishing.
Anti-phishing Domain Advisor Visicom Media inc (powered by panda…
Yes, I just did so!
did what?
I just installed Anti-phishing Domain Advisor as you advised.
you mean uninstalled / removed ? as that program may be the problem …
No, I installed it, I thought you were advising me to install it. Since I have installed it I haven’t gotten the annoying pop-up from Avast. But I also installed Comodo firewall.
Every time I scan I get Threat: Win32:Small-NNE [Trj] in file: C:\Users\admin\AppData\Local\searchcom_003\data\120906112445-f.list
I delete the file but it returns within seconds. No other scanners will detect the threat. There is little help on line other than people selling removal software. They make this threat sound very dangerous to my computer’s security. I have even seen a couple of sites saying that it is doug in so deep into the system that it can’t be removed. Have the brains at Avast figured out an update to get rid of this pest?
Hi shawnmberry,
Thanks for showing us the path for that list file.
Searchcom_003.exe seems to be another product from visicommedia.
Emsisoft deems searchcom_003 safe http://www.isthisfilesafe.com/ search on product for searchcom_003.
Most likely, your pc is not infected with Win32:Small-NNE [Trj]. You could just uninstall the visicommedia product to get rid of the detection.
Explanation. Visicommedia uses Panda [another antivirus company] virus signatures to deliver to you a safe browsing experience. Unfortunately, Panda does not encrypt their signatures. Avast detects those signatures in the .list file as the real thing and gives you an alert.
Best regards,
