I keep getting a pop-up that says I have the trojan horse “Dropper.Small.5.F” and to get rid of it I should run AVG anti-virus.
I’ve run it, re-booted, downloaded the newest version, ran it again.
I’ve also ran AdAware and SpyBot, to no avail. Apparently, I still have it.
Anyone know how I can get rid of this?

Are you running XP or ME? If so, disable system restore. Reboot. Run a full system scan. Enable system restore and make a new restore point once you are all clean.
As an added precaution, do an onlice scan at [Housecall.](http://housecall.trendmicro.com/housecall/start_corp.asp)

Alrightee! (I am running XP.) Erhm… can you tell me how to do that? And then I will be ignorant no more forever.

Nevermind. I found it. (Evil sin of sins: Not looking up the answer first before asking someone to help you!)

Sorry I missed your post.
Did you get it?
Right click on My computer…choose properties…and go to the restore tab.
How’s it going?

And if that fails, head over to [http://www.moosoft.com/](http://www.moosoft.com/) and download the trial version of The Cleaner. I’ve found it useful on really tough buggers that don’t want to die.

Thinking it over, that sounds an awful lot like what I got into a couple of weeks ago. It took The Cleaner to finally smack the bustard down. It took me six hours and the Cleaner was like the eighth AV program I tried. A true pain in the ass - I only had a couple of programs with me and had to downlaod the others over a single ISDN line (64Kbit.) It sucked big time, and I didn’t get home until like two in the morning.

So far, so good. Thanks for the tip. Tried to logon to housecall, but it was taking forever, so if I get the dialogue box thing again, I’ll go to that site.
Can you tell me, in laymans’ terms, what I did, exactly? (I’m just curious.)

What you did? As in how you got the trojan? (can’t really say.)
Or as in…what you did by turning off system restore?
Doing that, purges your computer of the system restore points it has made. Which, is most likely where that trojan was residing.
Were you able to finally log into Housecall?
What AV are you using? If you have none, might I suggest [AVG](http://www.grisoft.com/us/us_dwnl_free.php) ? It’s free.
