Is this a Virus on my macbook

Question

My macbook was recently running slow when on safari and I had stupidly downloaded one of this adobe updates prior to this so I am assuming that this was the result of it running slow.
From looking at different forums I downloaded the ClamXAV app to run a check on any virus on my macbook.  It has returned 73 infected files.  They look more like email phising virus.  They range from :
Filename
Infection Name
Status
/Users/kellymac79/Downloads/VideoPerformerSetup-1.exe
Win.Trojan.Installbrain-26
Filename
Infection Name
Status
/Users/kellymac79/Library/Mail/V2/[email protected]@imap.tools.sky.com/[Gmail].mbox/All Mail.mbox/FDA8FE41-5D1A-47BE-94ED-364379796D14/Data/0/6/Messages/60510.emlx

Email.Trojan-234
and other files which are similar.
What should I do.  Should I delete them myself or set up a quarantine folder.  If I do either of these will I then put them on my hard drive?
Im not technical at all so any help would be greatly appreciated.
Many thanks

For fastest, most efficient answers to questions such as these, come to the ClamXav Forum.
Since most of the ones you listed were e-mail messages you need to know this:
Never use ClamXav (or any other A-V software) to move (quarantine) or delete e-mail. It will corrupt the mailbox index which could cause loss of other e-mail and other issues with functions such as searching. It may also leave the original e-mail on your ISP's e-mail server and will be re-downloaded to your hard drive the next time you check for new mail.
So, if you choose to "Scan e-mail content for malware and phishing" in the General Preferences, make sure you do not elect to either Quarantine or Delete infected files.
When possibly infected e-mail files are found:
Highlight the entry in the ClamXav window's top pane that needs to be dealt with.
Right-click/<Control>-click on the entry.
Select "Reveal In Finder" from the pop-up menu.
When the window opens, double-click on the file to open the message in your e-mail client application.
Read the message and if you agree that it is junk/spam/phishing then note the date and subject of the message and close the e-mail window.  Now, using your e-mail client, locate that message in whatever mailbox folder it was found in and delete the message using the delete button.  Reading it is especially important when the word "Heuristics" appears in the infection name.If you disagree and choose to retain the message, return to ClamXav and choose "Exclude From Future Scans" from the pop-up menu.
If this is a g-mail account and those messages continue to show up after you have deleted them in the above manner, you may need to log in to webmail using your browser, go to the "All Mail" folder, find the message(s) and use the delete button there to permanently delete them from the server. Then check the "Trash" folder and delete them there.
