On April 27, on my 1 GB RAM desktop running Windows XP Home, following a Norton Insight Scan, I manually quarantined the files listed below because they had low levels of trust (most of them 5 users in the Norton Community, 2 weeks or less old, and no proper digital signatures). My Microsoft security patch and operating system updates have not installed properly since May 12. I was wondering if any of the files I quarantined might actually be essential system files which would prevent security patch and op system updates by their absence. My Firefox 12 has been running very slow on Yahoo and Facebook, and I was suspecting some type of virus attack since the malware/scareware that knocked out my daughter's computer last fall apparently stopped operating system, security patch, and Virus Protection Software (One of Norton's less worthy competitors) updates for about a month before it became obvious. Any guidance or thoughts would be appreciated. I am keeping the computer disconected from the network and Internet most of the time - I turn it on, run Live update, scan for viruses and turn it off. I just downloaded Norton Power Eraser, but have not run it yet. Thanks in advance!

There was an issue with Norton and digital signatures in .msi files (although it should not affect 2012 products), so that may have contributed to the low reputation score. Nevertheless, a low reputation trust level simply indicates that not enough is known about a particular file for Norton to treat it preferentially. In other words, it will not be skipped during scans. If the file were actually malicious or did something suspicious, Norton would quarantine it automatically. Users should not remove files based on the reputation rating that Norton assigns - the rating has nothing to do with whether a file is actually a threat. You should restore those files from Quarantine.

There were no indications of virus inflection from the scans. I restored the quarantined files, and yippee, my next attempt to download and install the Microsoft operating system and security patch upgrades finally succeeded! Thanks, Guru, for the timely good advice!
