Specs: Windows 7, 4GB
I have a virus on all of my systems on wifi LAN. When I tried to flush through prefetch cmd the virus read DLLHOST.EXE-71214090.pf. The antivirus on all the systems is Microsoft security essentials which doesn't recognize it. How can I remove this virus manually? Thanks. The OSs of the systems are vista, win 7 and win 8 all mixed.

Why do you believe that there is a virus in your computers? The presence of multiple DLLHOST.EXE entries in the prefetch folder is normal and does not indicate a problem.

Download OTL from any of the following links and save to your Desktop.
Double click the OTL icon to start the tool. (Note:If you are running on Vista or Windows 7 accept UAC alert)
When the window appears, underneath Output at the top, make sure Standard output is selected.
Select Scan all users
Change Drivers to All
Under the Extra Registry section, check Use SafeList
In the lower right corner, checkmark "LOP Check" and checkmark "Purity Check".
Click Run Scan and let the program run uninterrupted.
When the scan is complete, two text files will be created on your Desktop
OTL.Txt <- this one will be opened
Extras.txt <- this one will be minimized

Upload the logs using this. I upload to Imgur.com for images & load.to for files ( neither need an account ) Give us the link please.

"When I tried to flush through prefetch"

Not sure what you mean by this but you will never clear a virus by deleting things in prefetch.

Always pop back and let us know the outcome - thanks

I recommend a program called rouge killer.it stops the process and looks for faked and changed system files.
