AVG Anti-Malware 7.5 & BITDEFENDER Internet Security 9

Hi.

I just ran a “scan” on my C Drive (the primary one like eveyone else)with GRISOFT AVG Anti-Virus & And Software 7.5 (the anti-Malware package, both plus editions).

In GRISOFT AVG Anti-Virus Test Centre, I see several files marked “Change”:

Files Results/Infection Location
kernel32.dll Change C:\WINDOWS\system32\kernel32.dll
user32.dll Change C:\WINDOWS\system32\user32.dll
shell32.dll Change C:\WINDOWS\system32\shell32.dll
ntoskrl.exe Change C:\WINDOWS\system32
toskrl.exe

I’m not sure what this suppose to mean. These is a big green square with a tick in the top-right corner of AVG Anti-Virus Test Centre.

AVG Anti-Spyware makes no comments like this.

I also have Bitdefender Internet Security 9 (BIS9) which also includes Anti-Virus & Anti-Spyware. BIS9 makes no such comments either.

I also noticed that when scanning with BI9, I see “detected:[name of virus/spyware]” in the result but it doesn’t do anything about: it doesn’t delete them or quarantine them or even heal them. So these “detected” stuff are just left there on my PC? The only thing BIS9 can do at the moment is ask me to send these files to their lab after the scan has finished.

Can anybody explain what has happen, if it’s good or bad & do I need to take further steps for the sake of my computer’s health & security?

These are my PC’s Specs:
Computer
-Pentium 4
-CPU 2.66Ghz
-DDR RAM 512MB
-Physical Address Extension

O/S
-XP Professional
-Version 2002
-SP2

My PC Security Info (as stated above):
-Bitdefender Internet Security 9 [Anti-Virus & Anti-Spyware but no Firewall]
-AVG7.5 Plus Anti-Virus [no Firewall]
-AVG7.5 Anti-Spyware Plus [no Firewall]
-Windows firewall (the one that came with XP I guess)

Thanks.

I believe this happens sometimes after installing patches through Windows Update, it means those files have been replaced by newer versions. If that is the case, then there’s no risk because those are legitimate files and you can click “Confirm changes” so that in the next scan AVG won’t report those files (unless they change again, of course).
