I am using windows 8. last night i inserted a usb drive into my laptop and scanned it. while opening the drive many files are not visible, and folders were displayed as shortcuts and the autorun.inf was present there.
after that i could see that below 2 urls are invoked at regular intervals and blocked by avast
nnh42.name/a/
jsh37.net/a/
otl, ccleaner and the pc settings wont run in normal mode. so i did an otl scan in safe mode. log is attached herewith.
Please help.
aswmbr log attached…
Bear with me I know what the infection is but I need to switch to my windows 8 system to ensure that the instructions work there
thanks for the concern. but this issue is bugging me a lot. will the steps be the same as that of windows 7 ??
Nope as windows 8 trusted installer is slightly different to windows 7
Go to C:\Windows\System32\Wscript.exe
Right click and select properties
Select the Security tab
Click Change alongside Trusted Installer

No I have just learnt from those that had this previously and managed to hone the fix
Subject to no further problems
I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems
Now the best part of the day ----- Your log now appears clean 
A good workman always cleans up after himself so…The following will implement some cleanup procedures as well as reset System Restore points:
Run OTL and hit the cleanup button. It will remove all the programmes we have used plus itself.

Go Start > All Programmes > Accessories > System tools
Right click Disc Cleanup and select run as administrator
When it pops up at the first prompt select OK after it has done some calculations the tabs will appear
Select More Options tab
Press Sytem Restore and Shadow Copies Cleanup button
