About a month ago, I noticed that my laptop was doing an AntiVirus scan at boot up. This really dogs the system and it takes up to 10 minutes for it to finish. I originally set the antivirus up to only load and monitor and had also turned off any administrative or user scheduled scans. This has worked great for years.
Now, it starts scanning at boot up.
This is the older Symantec Coporate Edition 10.1.0394. The laptop is a member of a group called LAPTOPS that has settngs to not do a scheduled scan. AUTOPROTECT is on and the user has no ablitly to end the resident virus protection.
At first I thought some settings had been changed, but I have reviewed the settings and it appears nothing has changed. I also have confirmed that no viruses are being reported and risk history is blank. I unistalled the client on my laptop and reinstalled it thinking something was hosed on the laptop, a registry entry or something, that would tell it to do a scan at startup. It still scans at bootup.
This was a problem that we experienced when we first installed the product that was solved by setting administrative settings.
So here is my questions.
1) Why is the scan running?
2) Is it possible NAV thinks there is an issue (a virus was detected previously) and is doing a scan for protection?
3) Since the settings say "when file is accessed or modified" is it possible it is scanning all files that are opening at startup, and if so, why now does it dog the system so after a couple of years of being unoticble?
3) If I change my setting for "Scan files when" to MODIFIED (scan on Create) does this trully open up a bigger risk of infection?
Also I am running a defrag to insure the files are not fragmented.
Some expert advice on this will be greatly appreciated.
