deleting malware that only is in time machine

Question

deleting malware that only is in time machine

IMac OSX 10.9.4; 2.8 ghz Intel Core 15; 4GB 1333 MHz DDR3

I have malware files which have been removed except they were not removed from my time machine backups. My antivirus software automatic clean up failed clean and indicated that a manual cleanup is required. I can fine these files quarantined by the software. They are in download files but I do not know how to remove these files. I am somewhat computer davy, but this is out of my understanding. Could someone provide clear step-by-step directions for accomplishing this.

Below are 2 excerpts from the log file.

Assuming the identification is accurate, those are Windows trojans that can have no effect on OS X. I suggest you ignore what the "anti-virus" software is telling you, or preferably, get rid of it.

The items being identified are "keygen" apps. In other words, they are used for stealing software that you don't actually own. One of them, at least, is a Windows keygen app, but the other two are in .zip files, so it's impossible to say whether they might be Mac apps or not.

If you have been engaging in software piracy, you need to stop immediately. Ethical issues aside, this is an extremely dangerous activity, as it involves trusting and opening apps that are given to you by criminals. This is never a wise thing to do, and can easily result in getting infected with malware. Anti-virus software cannot protect you if you are doing your best to download and run untrustworthy apps.

The anti virus is Sophos. I'm perfectly OK with ignoring it. Will it bw a problem if I have to restore files from my time machine?

Thanks,

Thanks to all of you have responded to my post.

I have Parallels software on my MAC. Quicken is installed on the Windows side. Quicken support found the trojans and referred me to I FIX PC. They cleared and removed the trojans on both my MAC and My laptop which only has the Window's OS. They installed the Sophos software.

Since the Sophos was new I decided to see the results of the scan I checked the Sophos Quarantine manager and it said that the above files could not be automatically removed and had to be done manually. Exploring further, It appears that software I downloaded in 2012 was infected. At that time my Norton Antiviral software found a virus. Because of that I have never used a torrent again. These programs were on my windows computer or. I transferred the Photo manuals folders to Mac and have never opened them. I have uninstalled all of the Photoshop and associated software then from my laptop computer. My Photoshop for Mac is legit. I did not remember that I had saved the programs on my Maxtor external hard drive.. I have deleted all of them. Would that perhaps solve my problem? If not I will pursue the suggested solutions posted.
