a few days ago, I downloaded a file via Torrent which was seemingly infected. A bunch of tmp files started getting reported as security threats by AVG, so I let it clean them up and performed a full test to clean up the rest. However, every so often a new thing popped up. Seeing as the file I downloaded didnt work anyway, I was ok with just doing a system restore before the time I downloaded. Unfortunately, that didn't work (unexpected error, not caused by antivirus, turned AVG off for the restore as per the windows recommendation). So I went along with it, security threats weren't popping up anymore, so I thought maybe I was safe. Except now, a SecurityHelper.dll gets reported every time I launch windows. I looked it up on the web and all the advice on removing it has been useless (the associated processes, .dlls, registry locations etc. which I am being directed to aren't there on my PC, and advice such as "use the software removal tool for securityhelper.dll" obviously won't work either (not to mention that AVG removes the file every time I launch)). Seeing as this virus is kind of a big deal and I use the PC for work, banking etc. I really need to get rid of it (the system is relatively fresh but reinstall is the last resort for me). My system uses win7 (which is perhaps why some HKEY directories are different than in the guides)...though I suppose you will require full system info anyway. Can you help me please?
