I have no choice to delete those infected System Volume Information Infected by trojan, I'm worrying if It will affect my PC Performance. :C
-
I'll attempt to guess where you are. You have performed a scan, and it found stuff. (Either that or you have a scan report that has some entries: "Unable to scan: the ...")
Following the scan where malware was detected, the "repair" option is not available.
If it were trojans found, they can not be repaired; the entire file is malware. Only certain system files might be repairable by Avast. And the repair is not 100% guaranteed.
(There is generally no need to delete files that are simply "unable to be scanned" following a scan. If suspicious, these files should be further investigated before taking any action.)
Any files in a folder named "system volume information" are to do with the system restore function. If they contain trojans, it is correct to delete them, but be aware that the restore point associated with that file will not be operable afterwards.
If trojans were found, it would be wise to follow up with a second opinion scanner, such as MalwareBytesAntiMalware (MBAM for short) or Superantispyware (SAS for short.)
Deleting files from the folder indicated will not effect your computer performance at all, except to void the restore point concerned.
-
So, Sir. Uhm, Do you think that they will be back? D:
Coz before when I'm not an Avast! User, Stuffs like that always back :C
It's not unable to scan but, It can't be repair. I generate the VRDB. I read that It will return them exactly to their original state.
-
No, the file information collected by the VRDB will have no effect on trojans. The VRDB collects and stores information that might be useful in restoring (repairing) certain system files if they get corrupted.
Trojans are a completely different animal to viruses. Trojans will not corrupt system files; they are executables in themselves. No repair is possible.
What AV did you use before Avast? How was it removed? What other security software do you have installed?
What are the names of the detections your recent Avast scan made?
-
Now I know. Thanks for that Very helpful explanation. :)
I Use AVG 1st before I use avast!. It detect a trojan horse in win32.
But I'm not satisfied because it scans all over and over again for a long time but
I think it don't scan very well. Before I create this topic, Avast detected some 12
infections including malware and adware. Trojan is there too, Like what I said, The trojan was in System Volume Information. I create a topic like this because I'm worrying about that infection. I don't install any security stuffs, except avast!.
-
Don't worry too much about a detection in "system volume information". It can only become active if you use system restore.
(To delete all restore points, and any trojans in them, turn off system restore, reboot, turn it back on. This should only be done if the computer is running well.)
Did you uninstall AVG? If not you need to do so, and to run the AVG remover, get it here. (http://www.avg.com/download-tools) (For most users it will be the first tool, 32bit windows.)
2 (or more) resident AV's should not be run together. Sometimes it can be done, but usually there will be problems.
I recommend a demand scanner. Download MBAM (http://www.malwarebytes.org/mbam.php) and/or SAS. (http://www.superantispyware.com/download.html) Both have free versions. Both can be run alongside Avast, no problem. The free versions are demand scanners only; no resident protection. Both are very good at malware detection and removal.
Other tips:- Consider a two way firewall. The one I use is fairly easy to work out.
- Make sure your copy of Windows and all programs on it (Like Java) is up to date.
- Consider an immunizing program like SpywareBlaster. (http://www.javacoolsoftware.com/sbdownload_free.html) This can block known bad websites.
- Clean temporary files regularly, say, once a week, or daily if preferred. Defrag every month or so.
-
Yes Sir, I uninstall it with a removal tool. And I'm done also with the restore thingy.
Alright, I'm currently DL'ing the SAS. You sure that It's safe in pc's huh?
-
Superantispyware is reputable, safe, and recommended frequently at this and other forums. Good idea to ask. There are a lot of rogue programs around.
-
Sir, Is the link that you gave me is the full and not the trial version? Yay, Your right sir. After I install it, It detect a 2 stupid trojans lol. I'm glad that you recommend me
that one sir! ;)
-
There are two versions. The pro (upper) or the free (lower on the download page.)
If you want to install the free, and later decide to upgrade to the pro, the upgrade fee is a good deal, in my opinion.
I'm quite happy with the free version, myself.
-
Yay, I DL the Pro one. D:
I guess I have to DL the free one. After this scan. I guess the 8 trojans 2 malwares
and 1 rootkit are the suspicious ones that's why when I got my PC Start up, My Documents Just appeared. D: rogue ones are everywhere. True, experienced by me. :) I'm 100% Sure that I got those stuffs in torrent DL's. I DL a Movie last week and
I'm using AVG that time so, I guess it didn't detect those ones. I'm exactly right, AVG Is just for USB Scans. I'm happy that there are so many guys like you around here that willing to help to those people who needs help. =D

Btw Sir, Are you sure that Free version would be fine for my PC? I can't find a good reg #. :C I Know you know how and where to find Please? :c
-
Broke my computer, once, trying to fix the registry. Some registry cleaners can be a bit too aggressive, and do damage.
If you don't know much about the registry, it can be a problem if the wrong entry is removed. Programs can stop working.
So in suggesting a registry cleaner, I'm going to recommend two that are reasonably tame. And say that you should always make a backup of the registry before cleaning it.
The popular file cleaner, Ccleaner (http://www.ccleaner.com/), has a registry cleaner included. Also has a helpful forum, and many users.
Less popular, but has never given me a problem, is Tweaknow. (http://www.tweaknow.com/RegCleaner.html) It will also place the results into "safe", not fully safe" and "unsafe" sections. (I suggest you only remove the "safe" ones unless you know what you are doing.
Any chance of seeing the SAS scan report?
-
It scans good, but Enable real time protection can't be used. I guess, because of free Ed. I guess this's working fine now. Are you using PRO version? Did you pay for it?
-
See bold item above. (http://forum.avast.com/index.php?topic=45749.msg383373#msg383373)
-
Sorry about that.
I always generate the VRDB. Am I doing right? Sorry, The last time I use avast is when I was in 2nd yr HS. :C
Thanks and have a nice day! ;)
-
The VRDB generation will occur after first installing Avast, and can take well over an hour, plus maybe a restart. After the first generation, it will remain idle unless ordered by the user, and re-generate every 21 days.
It is not necessary to generate one yourself, unless you've just installed a service pack or something major like that. I usually set mine to generate when the computer is idle, and forget about it. My icons are merged.
-
Alright sir, Thanks to your help. I guess this has been solved. ;)
Thank you very much!
-
Bump,
Sorry for this one but. It says that I need some registration key for mbytes.
TIA!
-
So you downloaded MBAM?
What says you need registration keys?
-
When I enable protection to block those harmful stuffs. :C
-
That will be because you have the free version of MBAM, and if you wnat resident protection, you will need to purchase the program. Once you have done that, they will send (email) you a key, which will activate the resident protection.
Most of these sort of things work in a similar fashion.
Is this the picture you are seeing?
-
Yes sir. That one. If I purchased. Is there a fee? :|
-
Of course there is a fee.
When you open the program, click on the "about" tab, (at the top right) then click "purchase", and your browser will open to the purchase page.
Or you could just use it as a demand scanner, not worry about the resident protection. Up to you.
-
Oh, Alright. I change SAS I'm not satisfied. And now I use Mbytes.
I guess I have to use Ccleaner too, But Everytime I used to click the link of their site in google, It says Page Load Error. :|
-
SAS is exactly the same sort of situation; if you want resident protection you will need to purchase it.
Ccleaner is a useful file cleaner. (So is ATF cleaner, by Atribune.)
Up to you if you want the added resident protection of an antimalware application. Personally I'm quite happy with a firewall, Avast, and running a demand scanner once a month or thereabouts.
I also use Threatfire, a behaviour blocker, and, perhaps because my system and all software is kept very up to date (which limits the types of malware able to install on it) Threatfire has never alerted me to anything nasty.
-
I want to DL Ccleaner but When I go to their Home Page, It says that Page Load Error. :|
Threat fire is like 4x firewall? What are the benefits? Is It user friendly? D:
And I have a question about avast! again. :| I read some reviews from google and some stupid guy said that "but still it lacks heuristics features" Can you explain about this one? What does he mean :|
-
What is the URL you used for the homepage?
Threatfire is not a firewall.
It is, as I said, a behaviour blocker. I find it user friendly; some users do not, it depends on how much you learn about it, via the help files, or research about behaviour blocking generally.
Personally I think you need to learn more about what the various internet threats are, and how to protect yourself from them, rather than installing applications and hoping they will do the job.
Find out what you want to achieve, then find an application (or user procedure) that will provide for that.
I read some reviews from google and some stupid guy said that "but still it lacks heuristics features"
Why do you ask this? Are you interested in studying stupidity?
You can find things on Google that says almost anything. Doesn't mean it's valid. And I'm not interested in following this line of discussion, unless you come up with a better source or reasoned argument.

Sorry, Coz my bro keeps on saying. NVM, Sorry. Thanks for the Advice. Have a nice day.
-
What's "NVM"?
-
NVM = NeVerMind
I have another question, Regarding the avast! Tray scanner at lower right side of my desktop. I got an error the GPU error. I can't read that error exactly because I accidentally close it due to nervous. :c the tray avast scanner icon was gone after that.
I restart my pc thru button restart in CPU then It's back. What's the problem about this one?
My Avast! Home edition is already up to date. I wonder why my VRDB hasn't updated yet. but the Program is up to date. I set VRDB update to automatic mode. But I update it manually. And it says that it's up to date.
Does this avast! tray icon scanner can last until I decide to turn off my PC?
How about this one?;
That upgrade one, =/[(http://img32.imageshack.us/img32/2426/323z.jpg)
And one more question, avast blue tray scanner at lower right side don't spin when you don't use your PC right? Example for process and etc.
I'm sorry. I didn't use avast! For a long time. The last time i use it is when I was 10 y/o
And for the Outlook/Exchange it says that "The provider is waiting for a subsystem"
is that normal? I'm asking this because of what happen to my avast home ed.
-
A GPU error is to do with graphics processing. Without knowing more it's impossible to say what might have caused it, but the likely scenario is that the display of Avast was missing, but the other processes were still working.
When you restart, all is back to normal, therefore probably no need to be concerned. The "blue ball" should remain in the system tray as long as Avast is installed. If this happens again, note the full error message and post back.
My Avast! Home edition is already up to date. I wonder why my VRDB hasn't updated yet. but the Program is up to date. I set VRDB update to automatic mode. But I update it manually. And it says that it's up to date.
Thought I might have answered this here. (http://forum.avast.com/index.php?topic=45749.msg383607#msg383607)
The upgrade banner is a recent push by Alwil to promote the Pro version of the AV. The Pro version has a few more features than the Home version. Comparison chart. (http://www.avast.com/eng/avast-compare-home-professional.html) Up to you if you want to do this.
The Avast icon (blue ball) will spin (if it is set to, by default it is on) whenever a file is being scanned. So when the pc is not being used for anything...downloading or running applications, it will remain still.
Regarding the subsystem, that means that if you are not using Microsoft Outlook (not to be confused with Outlook Express: both are email programs) the provider is available, but has nothing to do as the program it is designed to protect is not running. If you don't use MS Outlook, you might as well terminate that provider.
All clear?
-
Yes, All clear. That means I don't have to worry. Thanks to you. You can now close this thread sir. ;)

The one thing I would suggest in your image, you will see a button called Details... >>, click that and it expands the window to show a 'Detailed' view of all of the individual avast Shields (Providers)
