I was doing my weekly ccleaner cache cleaning as I walked out of the computer room. Upon returning, avira had notified me that it discovered a trojan virus:

Virus or unwanted program 'TR/Gimemo.E.1 [trojan]'
detected in file 'C:\Users\****\AppData\Local\M​ozilla\Firefox\Profiles\j968​nyq2.default\Cache\C\20\9535Ed01.
Action performed: Transfer to Scanner

The thing is, the trojan was detected in a spot that CCleaner was cleaning, so it was already wiped before I could take any action in avira, although I did still click to remove it. Comodo was also requesting a program attempting to change the registry, which I blocked.

Now, I have scanned with malwarebytes, spybot, superantispyware, MSE, Avira, Trend Micro Online, Bitdefender Online. I have now decided to change my security software to Avast! + Threatfire + Comodo. Instead of just Avira + Comodo.

I am doing some boot scans at the moment.

None of the future scans since those first two events have turned up anything, nor have I been redirected or had any symptoms. Internet is a bit dicey, but that is for all computers on this internet at the moment...

...does this mean the Trojan file had not been deployed? Did CCleaner somehow stop it doing anything by deleting it?

How come no other scanners have detected even a whiff of this? They all have been updated prior to scanning.

The infection is located into the Mozila Firefox profiles cache. It's logic that Avira alerted now, because you were removing the Internet files and other files with CCleaner and then Avira saw the infection.

Do you have any other symptom of infection?

1. Follow the instructions "Preparation Guide For Use Before Using Malware Removal Tools and Requesting Help" and create a DDS-log.

Now that your log is properly posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a Malware Removal Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the Malware Removal Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the Malware Removal 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 make another reply until it has been responded to by a member of the Malware Removal 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 MRL Team member is already assisting you and not open the thread to respond.

The current wait time is 1 - 3 days and ALL logs are answered.

If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.

To avoid confusion, I am closing this topic.
How do I get help? Who is helping me?For the time will come when men will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear....Become a BleepingComputer fan: Facebook
