I was glad to see za brought out a vista 64 bit version. After installing the new program ( extreem security) my system froze up with in a couple of days. I noticed that the c drive had no available space. I then found that the windows temp folder was full of pr temp files. not sure of what happend. I cleared them out, but the next day it was full again and the computer was frozen again. after I cleared them out again, I shut down ZA for the night and unplugged the nic card to see if they would show up. they didn't. I then ran ZA AV scan and they showed up and filled the directory. When I examine the files they appear to have info form my zip files. Is there a reason that ZA would be writing these files to the temp directory. Virus scans show nothing. Any ideas or help is welcome.
