Short answer to the only question you asked is Yes, you can delete the contents of the temp folder.
But you have to ask yourself, if you have AdAware, and Spybot Search & Destroy, and NIS 2005, and you update them regularly and run scans regularly with them, how come you still get spyware and pop-ups?
Are you doing these things? Are you updating Norton's Antivirus and running it to scan your PC regularly? Are you doing the same with Adaware, and Spybot? Is Norton's Firewall on all the time?
What are you doing that infects your computer with spyware and pop-ups?
Is your Windows updated regularly? Have you installed Windows Update SP2?
Do you download files using a P2P file sharing program? Do you share infected disks from other people? Do you download programs from the internet? If the answer to any or all of these is yes, do you scan the disks or programs or files for viruses "before" you let them loose on your computer?
To help clear your computer now, goto
