You're not going to like what I have to say. You do have one of the nastiest out there - Virut is a polymorphic file infector which affects the executable files (.exe), screensaver files (.scr), .htm, and .html files, including critical Windows system files
, corrupting them beyond repair in most cases. Many security experts agree that a clean reformat is the only way to clean the infection and return the machine to its normal working state.
Have a look at our colleague miekiemoes' blog for similar comments and more detailed links about Virut here
All it takes is one file being missed by DrWebCureit or any other AV that claims to clean Virut, and the infection will rip through your system again. You would be well advised to backup all your personal data (documents, pictures ). DO NOT backup any executable files, i.e. software installers(*.exe), screensavers (*.scr), .htm, or .html files.
Also, try to avoid backing up compressed files (zip/cab/rar) files that have .exe or .scr files inside them. Virut can penetrate and infect .exe files inside compressed files too. Burn your backups to CD/DVD. Do NOT copy files from the infected machine to your pendrive OR another machine. You risk infecting the other machine.
ComboFix will not
disinfect Virut so I'm not going to discuss running that tool with you at this stage. Run an online scan and let's see what Kaspersky has to say.
Establish an internet connection & perform an online scan with Firefox or Internet Explorer at Kaspersky Online Scanner
To optimize scanning time and produce a more sensible report for review:
- Close any open programs
- Turn off the real time scanner of any existing antivirus program while performing the online scan.
, when prompted to download and install the program files and database of malware definitions.
- Click Run at the Security prompt.
- The program will then begin downloading and installing and will also update the database.
- Please be patient as this can take several minutes.
- Once the update is complete, click on My Computer under the green Scan bar to the left to start the scan.
- Once the scan is complete, it will display if your system has been infected. It does not provide an option to clean/disinfect. We only require a report from it.
- Do NOT be alarmed by what you see in the report. Many of the finds have likely been quarantined.
- Click View scan report at the bottom.
- Click the Save Report As... button.
- Click the Save as Text button to save the file to your desktop so that you may post it in your next reply.
