Hello i am new to these forums and I have looked for help with these topics and i haven't really found any, so any help would be appreciated, and i hope i put this in the right section
First off I decided to go on Norton and check the history of what it has been doing and i notice a lot of intrusion attempts being blocked on Norton. It is from 10.177.0.34 and it's traffic description is "UDP, Port 53". Now i noticed on the history that it is pretty random, so im guessing its a site that i am visiting(i turned on notification of this just in case it is the site, and i can avoid it). But i figure i would ask people here if it something more serious. I mean Norton blocks it, but i would like to stop it from even trying. Oh its risk name is "port scan". And it is "medium" severity.
Also not sure if this will help buy my internet is T-mobile mobile broadband, and I only us IE(newest version) now that FF doesn't allow nor tons tool bar. I have a Vista home premium, x64 bit.
Alright second topic. Also when checking my history i noticed "Au_.exe" made 41 changes to my computer. This kind of worries me, but it is at the same time i decided to unistall Firefox. Now I know it was because of Ff, but my question is, is it a good change, or did i set something off when i uninstalled it?
Third topic, I recently went into my temp folder and noticed i had a ton of files that i haven't deleted (like 256 mb worth, i always used the vista computer cleaner) so i deleted those, but shortly after I noticed that "irsetup" shows up on it and i don't have permission to delete it)I have UAC turned off and i am the administer) so i was wondering what i can do about that
And the last topic, all of a sudden today(well i didn't run a scan for a day or so, so it could have been in between that) My Norton doesn't fully scan my computer in "full scan mode", I normally have 600k+ files on both my c and d drive (500k+ is on my c) and now when it scans its only like 230k. So i decided to right click the c drive and scan it that way, a few more files showed up, but not all of them. I than decided to scan a specific file in the c drive and it also came up with a few more file, but was way off.
I decided at that point to shut off my computer and boot up in safe mode. When i did that it did a complete scan (630k ish) and didn't find anything, and i also decided to run spybot, and nothing was found. The only thing i found when it did the quick scan(pre safe mode) was some cookies, but i get those all the time and shows up in the can all the time( i use Google).
I would like to know what i should do about that, and if its a virus causing this or not. Im worried of reinstalling Norton, just in case it IS a virus and i wouldn't be able to reinstall Norton.
Also sorry about the wall of text, but i wanted to make my descriptions as specific as i could, so i can get an answer closer to what my problem is (yes i have looked some of this stuff up, but most of it wasn't that specific, and still left me wondering what to do). Also sorry for the multiple topics on one post, but i figured i would do one big topic, instead of multiple small ones, and save space.
Thank you for any answers you can provided, i am try my best to be a safe surfer online (i make sure it has the check mark from Norton, and i even read reviews about the site before i visit, minus sites i normally visit).
I just want to nip this in the butt, since i use my computer for a lot of things, and i don't want to risk the safety of my usage of my PC.
Oh i also forgot to add, i run the spybot Teatimer along with Norton for a week or two now, and it didn't have anything that popped up about something being wrong, or interfering with Norton. I also downloaded a windows update a week or so ago.
And can viruses be apart of Adobe reader? I noticed sometimes i had a download pop up that was "amazon" something and i denied it, and yesterday adobe was open, with out me reading a PDF and it popped up saying it was running and i couldn't shut down my computer until i closed it. I decided to uninstall adobe after that just in case. Again sorry for the wall of text.
Oh and I also forgot to add, IE crashed a few hours ago (well a tab) after it said it stopped a download when I was on basilmarket.com, Im not sure if this could be used for anything, but figured I would add this information.
And Also, when I start up my computer it sometimes starts up in 800x600 resolution(and mine is way higher) but I am able to change it back easily, so im not sure if it that is just a vista/graphics card problem.
EDIT: Forgot to add, I have NIS 2009.
