Hi and thanks in advance for anyone who might read this and offer help. I have been infected with malware/virus that just won't go away. I believe it's some form of the Trojan Vundo virus. The main symptom is that I have continuous popups as well as "invitations" to install programs to clean up my infected computer. More recently my computer has gotten sluggish and at times barely moves. I also get a message on occasion about Buffer Overrun Windows/explorer.exe (or something close).

I have tried various fixes including Vundo Fix, several virus scans such as Norton, TrendMicro Housecall, Panda, etc. Most remove some files but there is always something left over. Currently the file that won't go away is ddcyayy.dll I am at a loss on what exactly to do next, but from reading other posts on this website I believe others have had similar problems and have been helped.

Thanks again for any help you might be able to give me.

Hello SuzyQT1968

ddcyayy.dll is vundo related. Some variants of vundo may not be detected by Vundofix so the "Add more files" or "Drag & Drop" options are other ways of ridding this malware. These files need to be identified and posting a hijackthis log will enable an expert to advise you which files to add if you continue to have problems. If the infection remains after using VundoFix, then you should post a hijackthis log.

Please read and follow all instructions in the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log". In step #9 there are instructions for downloading HijackThis and creating a log. (This is a self-extracting version which will automatically install HJT in the proper location.)

Important: Some variants of vundo malware will hide certain entries in a hijackthis log to prevent detection so you need to rename HijackThis before using it.
  • After installing HijackThis, open My Computer or Windows Explorer and navigate to the HijackThis Folder.
  • Inside the folder, right-click on the HijackThis.exe file and rename it Scanner.exe.
  • Double-click on Scanner.exe (which is still HijackThis) run a scan, save the logfile and copy/paste it into a new topic in the HijackThis Logs and Analysis Forum, NOT here, for assistance by the HJT Team Experts.
Give your topic, a relevant title and post your log along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. Please include the top portion of the HijackThis log that lists version information. An expert will analyze your log and reply with instructions advising you what to fix.

Please be patient. It may take a while to get a response because the HJT Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT "bump" your post or make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.
