When I tried to install the Nero update, although there was a window for selecting their ads, Nod said that it was a virus of some adinstaller. It was just normal nero features right? I unticked automatic updated from the msconfig services menu, but didn't do it in the control panel. Now automatic updates still appears to be running. Doesn't unticking it in the msconfig uninstalls the program?
Check if you have enabled detecting of unwanted and unsafe applications. If yes, disable it and see if NOD32 still catch those files.
Nope, it was a sort of adware that NOD32 alerted on. Disabling Adware/Spyware/Riskware temporarily in the AMON setup should do the trick.
If you talk about Ask.com toolbar -> not exactly (from the FAQ) https://www.wilderssecurity.com/showthread.php?t=167358 It is detected as AdInstaller -> see (pictures taken for a thread here in the forum) https://www.wilderssecurity.com/attachment.php?attachmentid=189106&stc=1&d=1176512910 If something else is detected (with other name , for example) , then perhaps it is real threat
