Dual boot and Sun virtual desktop boxes! As installing multiple browsers.
I know this thread is pretty old but maybe my experience can help.
You have to tell Comodo that those files are secure, or just to bypass them when scanning, there's an "exclusion" menù somewhere in the antivirus settings. I set as exclusion both the zip and the folder where I want to extract it before actually extracting it.
Comodo can also create problems when setting up a local testing server. Again you have to tell it that your apache and mysql server are safe applications. I found these rules under defense+ -> HIPS -> HIPS rules (select the application and set it to trusted).
Note: my Comodo is in Italian, I just translated the menus that can actually be different, get the juice!
No need to get a mac.
