Windows 7: Shorcut virus.

Shorcut virus.

yesterday, my external hard disk was infected with the shortcut virus. i cleaned it after connecting to my desktop. everything went fine. and through web, i came to know that it only effected usb powered stuff and not hard drives.

but my c was infected. just documents and settings. and some important folders into that. like appdata, roaming, etc.
i went online and searched and ended up deleting something in regedit.exe also I go to task manager everytime and delete the scrip.exe, because i see hidden folders randomly named like 131b popping up from nowhere and creating java script files.

now the problem is i cant run a single exe file. no matter what i click, windows asks me "open with . . ". even if its snipping tool, brower or anything. what should I do?

i had created a thread in general discussion, please ignore it.

I'd suggest running Windows Defender Offline to check for malware.

Windows Defender Offline

Create the disk on a machine that is not infected and is running the same "bit-ness" as the infected machine. In other words, if the infected machine is running a 64-bit Windows 7 then the machine used to make the disk must also be 64-bit. Make sure your computer BIOS is set to boot from the CD/DVD drive as first option and then follow the instructions for running the scan.

I'd also check for any damaged or corrupt system files by running a system file checker scan from an elevated command prompt (option two.) If problems are found, run the scan 3 times and reboot the coputer immediately after each scan.

SFC /SCANNOW Command - System File Checker

In addition to marsmimar's excellent advice, it might be a good idea to also run the following tools, since not one AV gets everything. Rootkits generally alter Win files, some to the point that there is no option save for a repair install. If SFC is unable to correct the problem, you may wish to consider this option.

remoticboy,

Try the following:

Default File Type Associations - Restore

Let us know how it goes.


Just in case there are any malware remnants, also, download RogueKiller:
http://www.sur-la-toile.com/RogueKiller/

When you get to the website, go to where it says:
(Download link) Lien de téléchargement

Select the version that applies to your system: x64
Click the dark-blue button that applies.
Save to the Desktop

Close all windows and browsers

Right-click RogueKiller and select: Run as Administrator
Press: SCAN

When done, a report opens on the Desktop: RKreport.txt

Please provide the RKreport.txt (Mode: Scan) in your reply.
(Please do not delete anything!)

i tried what marsmimar said, but the bios didnt recognise the pendrive in which i had installed the windows defender.
and also, sfc scannow didnt work as well. everytime i run it, it says it needs to reboot because another a system repair pending.

what borg 386 said is great, but i cant use any exe file. it just wont open up.

and cottonball, I'll let you know.

You'll probably need to create the Windows Defender Offline bootable media on a disk (my BIOS doesn't recognize pen drives either. ) And the SFC probably won't work until after the malware scan has done its thing.

remoticboy,

See if this works...

Can you get to a Command Prompt:

Start > All Programs > Accessories > Command Prompt

Right-click the Command Prompt and select: Run as Administrator

At the blinking cursor, type in the following inside the code box, and press Enter:

Code:
cd c:\
Now, at C:\>, type in the following inside the code box , and press Enter:

Code:
assoc .reg
This command should return the following:

.reg=regfile

If not, then, type in the following inside the code box, and press Enter:

Code:
assoc .reg=regfile

Now, try to right-click the .reg file referenced in Post #4 , and see if it works.

Also, on RogueKiller, can you rename its downloaded file to RK.com and try it?

Maybe the comfile association works...
