Hi all !

I hope this isn't a repeat post, but I searched and found nothing about the subject. I am in the process of getting rid of Symantec since it let something thru that hijacked my hotmail account and was sending out e-mails about some Canadian pharmacy. It also didn't pick up a couple of virii that Avast did. I disabled everything Symantec and installed Avast and ran a fresh scan and Avast found 3 virii that Symantec missed.

Anyways, my BIG question is : What happens to the objects Symantec Anti Virus has in quarantine when I completely uninstall it ? I would hate to let those little buggers out to wreak havoc in my system.

Thanks for any insight all !

Normally, the uninstall wizard asks if you want to remove the items in the quarantine. You have to choose - yes to get rid of them. The items in the quarantine folder are kept in disabled state, they cannot cause harm.

But to be extra safe, delete all items in Symantec quarantine before starting to uninstall it. Read this how : http://www.ehow.com/how_5824714_delete-sym...ine-folder.html

When an anti-virus or security program quarantines a file and moves it into a virus vault (chest) or a dedicated quarantine folder, that file is essentially disabled and prevented from causing any harm to your system. The quarantined file is usually renamed before moving, safely held there and no longer a threat until you take action to delete it. One reason for doing this is to prevent deletion of a crucial file that may have been flagged as a "false positive" especially if the scanner uses heuristic analysis technology. Heuristics is the ability of a scanning program to detect possible new variants of malware before the vendor can get samples and update the program's definitions for detection. Heuristics uses non-specific detection methods to find new or unknown malware which allows the anti-virus to detect and stop if before doing any harm to your system. The disadvantage to using heuristics is that it is not as reliable as signature-based detection (blacklisting) and can potentially increase the chances that a non-malicious program is flagged as suspicious or infected. If that is the case, then you can restore the file and add it to the exclusion or ignore list. Doing this also allows you to view and investigate the files while keeping them from harming your computer. Quarantine is just an added safety measure. When the quarantined file is known to be malicious, you can delete it at any time by launching the program which removed it, going to the Quarantine tab, and choosing the option to delete.
