A small issue and a big issue in avast! free
« on: October 13, 2010, 09:54:40 PM »
My Pc is an HP 210-1000 Netbook
My OS is Windows XP sp3
My Avast! is Free version

Small issues first,

1, my computer likes to randomly switch to the windows classic theme and sometimes I
am unable to change the theme back. Also when this happens my sound stop(more like my
sound card stops working)and is unable to play music, sounds, and such.

With this problem I could'nt solve on my own so all I can do to temporarly
fix it is restaarting my computer. It's a pain and I think it's taking a toll on my computer as well since I'v restarted it so many times in a month.

2, avast is blocking more harmful data than usual while i am connected to the internet
specially while useing it. this could be a cause of a virus or so on my computer,
but here's a problem i'm concerned about mostly...

3, I custom scan my computer every night as i sleep(and by custom scan, it scan every inch and place on my pc) I've found about 9 to 15 infections...but
here's the problem

I cannot select an action to take for each infection and I cannot apply any actions as well, the apply buttion would'nt do anything so all i could do is close avast and let the infections go free...

if you need more info just ask

Try a scan with malwarebytes and when that is done do a boot time scan with avast.

Have you selected to scan memory ?

I recomend using the quick / Full scan with default settings

i see, good to know...the picture link shows some of my recent scans
and the password protected stuff, the list goes on and on, i did'nt
want to make a long screen shot...

so if it's on the memory and it's not a file, how would you clear that then?
would'nt shutting down restarting the computer clear the memory each time?

Edit: plus I had scan memory selected and been using it for a month now, this is the first this happened

Most of the files detected are System Restore Points. Those are files kept for back-up. Unfortunately, it seems like malwares itself, were backed-up as well. May I suggest you to delete your System Restore Points first.

  Clearing System Restore Points

1 Click Start, click All Programs, click Accessories, click System Tools, and then click System Restore.
2 Click to add a check mark beside Turn off System Restore on all Drives, and click Apply.
3 When you are warned that all existing Restore Points will be deleted, click Yes to continue.

  All system restore points are deleted. Now you should manually create a restore point.

1 Click Start, click All Programs, click Accessories, click System Tools, and then click System Restore.
2 Click Create a Restore Point, and then click Next.
3 Name your restore point. (I use the date as well as a descriptive term such as "After Restore Point Deletion.")

 Proceed performing another scan with avast.

fromthe link i posted above

- Detections in Memory
- Resulting from your having done a Custom scan in which you have elected to scan Memory, all these detections are in memory or are listings of files that can't be scanned. Since they aren't physical files they can't be moved to the chest, deleted, etc. so there is no action that can be taken, hence the Apply button being greyed out.

Quote
The detections in memory are frequently other security applications loading unencrypted virus signatures into memory. Having set off a scan of memory by an antivirus application looking for virus signatures, don't be too surprised if it finds some in memory.

meaning they arent virus but signaturs coming form some other security programs you have scanned with, have you ?

@.: L' arc :. : Backing up malware? not that's not good....cleared and done!

@Pondus : These are the security programs I use and scan with:

Avast! Free
Windows Defender
Wise Registry Cleaner Free

--
I'm going to perform another scan later and see how this is progressing..

Hi,
Win32:DNSChanger-VJ in your log seems to indicate your computer is infected with TDL. Try running Kaspersky's TDSS Killer and see if it finds anything.
