Hi
I would appreciate help with this. i recently ran a scan on my second deck top pc using A-SQUARED Free. The reults showed up an infection Virus.Win32.Virut.q!IT . I have quarantined this item along with eleven other traces that were found during the scan. Please see Log below. Can I remove this Virus.Win32.Virut.q!IT infection from my pc by simply deleting it or is there some other proceedure I need to follow to completely remove it. Also, can I delete the other eleven traces without causing problems ? The operating system on this pc is Windows XP Pro SP3.
Thank you
NONIC

If this is a confirmed infection, be aware that Virut (Virtob) / Virux are polymorphic file infectors with IRCBot functionality which infects .exe, .scr files, downloads more malicious files to your system, and opens a back door that compromises your computer. Virux is an even more complex file infector which also infects script files (.php, .asp, and .html). When Virut creates infected files, it also creates non-functional files that are corrupted beyond repair. In many cases the infected files cannot be disinfected properly by your anti-virus. When disinfection is attempted, the files become corrupted and the system may become irreparable.

The virus has a number of bugs in its code, and as a result it may misinfect a proportion of executable files....some W32/Virut.h infections are corrupted beyond repair.

McAfee Risk Assessment and Overview of W32/Virut
This kind of infection is contracted and spread by visiting remote, crack and keygen sites. These type of sites are infested with a smörgåsbord of malware and an increasing source of system infection. However, the CA Security Advisor Research Blog says they have found MySpace user pages carrying the malicious Virut URL. Either way you can end up with a computer system so badly damaged that recovery is not possible and it cannot be repaired. When that happens there is nothing you can do besides reformatting and reinstalling the OS.

...warez and crack web pages are being used by cybercriminals as download sites for malware related to VIRUT and VIRUX. Searches for serial numbers, cracks, and even antivirus products like Trend Micro yield malcodes that come in the form of executables or self-extracting files...quick links in these sites also lead to malicious files. Ads and banners are also infection vectors...

Keygen and Crack Sites Distribute VIRUX and FakeAV

If your computer was used for online banking, has credit card information or other sensitive data on it, you should disconnect from the Internet until your system is cleaned. All passwords should be changed immediately to include those used for banking, email, eBay, paypal and online forums. You should consider them to be compromised. You should change each password using a clean computer and not the infected one. If not, an attacker may get the new passwords and transaction information. If using a router, you need to reset it with a strong logon/password so the malware cannot gain control before connect again. Banking and credit card institutions should be notified of the possible security breach. Because your computer was compromised please read:There is no guarantee this infection can be completely removed. In some instances it may have caused so much damage to your system that it cannot be completely cleaned or repaired. The malware may leave so many remnants behind that security tools cannot find them. Many experts in the security community believe that once infected with this type of malware, the best course of action is to wipe the drive clean, reformat and reinstall the OS. Reinstalling Windows without first wiping the entire hard drive with a repartition and/or format will not remove the infection. The reinstall will only overwrite the Windows files. Any malware on the system will still be there afterwards. Please read:However, a-squared products are prone to "false positives" and they even acknowledge this.

...Sometimes security software falsely identifies important crucial system components as a threat (hence the term False Positives - FP).

Removing/deleting critical system files, even temporarily, can make a system crash. Sometimes the system will recover after a reboot, and sometimes it will not. Therefore, you may not be able to start your system. Special system restore measures may be needed, or even a full system re-installation.

...If detections are FP's, you run the risk of rendering your system inoperable...

a-squared HiJackFree: Using security Software to scan data
a-squared Anti-Malware: Using security Software to scan data
a-squared Free: Using security Software to scan data

...the a-squared Scanner looks for files, folders, registry entries and Tracking Cookies that are typically created by Spyware programs. Traces are exactly these trails that Spyware leaves behind.

This approach has both advantages and disadvantages for Malware recognition...The negative side is that it provides a relatively inexact, or insufficiently differentiated to be more precise, Malware recognition. Benign software can be falsely recognized, for example, if it uses the same file name or folder as a dangerous Spyware program.

Software discovered via Traces should therefore first be double-checked to see if it is actually Malware before it is finally deleted...

Spyware Traces in Detail

Always get a second opinion. For specific file detections, go to Jotti's virusscan or VirusTotal. In the "File to upload & scan" box, browse to the location of the suspicious file(s) and submit (upload) it for scanning/analysis.

If there are multiple file detections, perform an online scan with Kaspersky WebScanner.

Hi Quietman7
Thank you for your detailed response. I apologize for the delay in replying to your post but I have been slowly working my way through the links etc. trying to gain a understanding of what this is all about. I have uploaded the files idetified by A-Squared Free to both Jotti's Virusscan and VirusTotalfor analysis. Nothing was found in either of the scans. Kaspersky Webscanner was downloaded, updated and run but nothing was detected.
My PC seems to running OK with no obvious [to me] problems. Notwithstanding the security vunerabilities you mentioned, I would appreciate your help with this: " If the file C:\1a1e6fadf61bc652bf01fd\i386\ipconfig.ex_ is a confirmed Virut infection what anomolies in terms of behaviour / operating characteristics would my PC likely to be displaying ??
I am starting to wonder if the files identified by A-Squared Free may well be false positives. My dilema now is what to do with those files I have placed in Quarantine. Should I leave them there or restore them? Can some be deleted ?
Thank you for your time and interest in helping with this issue. Your support is very much appreciated.

If you uploaded that file to Jotti and it came back clean, then you don't need to do anything.

Given the track record of a-squared with false detections, I would restore everything, remove a-squared and repeat your scans with more reliable security tools. If Kaspersky did not find anything, that is a good sign. You can replace a-squared with programs like Malwarebytes Anti-Malware and SUPERAntiSpyware Free.

Then supplement your anti-virus by performing an Online Virus Scan like BitDefender.
