Alg.exe + Form1 keeps appearing after too many tries

  1. Hello everyone!

    I’m opting to post my strange problem into this great forum after trying for several hours to clean my computer from a weird process that keeps appearing every time I boot up the system. I hope somebody who had the same problem or someone with the knowledge will help me here. The problem begin after I download a file from the Internet , I download the file to my external HD where I keep all my important files back up but then I installed this in my personal desktop computer. After rebooting I then had the form1 on my taskbar for no reason, the program that seems to be doing this is c:\Program Files (x86)\Common Files\alg.exe

    I already tried to clean my PC and my external HD with Superantispyware, Spybot Search and Destroy and ESET Internet Security 4.x all of them with the most current updates, nothing really bad seems to be found but just some tracking cookies, the problem with the form1 process is still in my PC.

    I really don’t know what else can I try, perhaps I’m missing something? Is this form1 really a virus/Trojan or just a computer error? My PC seems to be running “fine” so I’m just closing this form1 process manually every time it appears. I also tried to search the Internet to see if there is any solution for this problem but there seems to be not that many people with this problem, I still couldn’t find a solution while I searched the Internet. I really don’t want to re-install my PC since I have too many software here (I’m work as a web designer).

    The alg.exe is not in your system folder, which is very strange. Its in this path > C:\Program Files\Common Files\alg.exe .... try to see if you find alg.exe in your system32 folder, if there is one, delete the other one. Then scan you registry with Ccleaner.

    Thanks for your suggestion Jawashh, Yes I found another alg.exe file in the system32 folder and I deleted the one you told me, for some reason I couldn't delete this file the first so I tried to delete in safe mode and it worked. I also install CCleaner and scanned my registry.

    The problem seems to be gone now after I deleted the file you told me, but I'm still afraid that the trojan could still be there since I use this desktop PC a lot for college stuff, online banking etc... Would you or somebody else recommend to re-install the my PC? or I should be fine?

    Here is my new Hijack new log:

    I don't think its necessary to re-install windows. Follow these steps:

    1.Scan you computer with Trend Micro Housecall 6.5 http://housecall.trendmicro.com/

    2.Scan you entire computer with Malwarebytes Antimalware http://www.malwarebytes.org/

    3.Make sure that you do not create many exceptions in ESET smart security.

    4.Check for new startup programs and try to disable unnecessary ones.

    I don't know if you have a trojan or not but use http://www.emsisoft.com/en/software/free/ to scan you computer and remove trojans if found.

    If you use this computer for the stuff you mentioned, make sure you don't disable your firewalls(hardware and/or software) too much.

    I also recommend you try http://technet.microsoft.com/en-us/sysinternals/bb897445.aspx to find rootkits(if any). Scan and tell me if it finds something.
