Sudden increase in quarantined viruses and trojans ?

Hi,

Can anyone please assist me what to do, because from what I have read, the DefWatch Wizard (defwatch.exe and Dwhwizrd.exe) most likely generates the DWH files. After virus definitions are downloaded, DefWatch is supposed to detect out-of-date virus definitions. During the process, quarantined threats are pulled out of the holding area and placed in a temp folder for scanning by Auto protection and DefWatch. When that occurs the Symantec scanning engine detects those versions of the previously quarantined files and the cycle keeps repeating itself ?

FYI: I'm using SEP 12.1 RU2 already.
