You might have received a quicker response if you posted in the correct area of the forum under Virsus/Worms section, however we can still help you here. The best option is to always put things in the Virus Chest where it is safe from other parts of your machine. If you delete it, it may contain vital files needed for your machine to work.
Check the information on the first post of this thread under Virus/Worms for you to check your machine for malware:

Follow the directions of obtaining an MBAM log (make sure you update MBAM first) and the OTS logs (save them as ANSI), and aswMBR log. Post the logs as an
attachment (Additional Options > Attach > Post).
I am going to refer you to our Certified Malware expert, named Essexboy. He will also review your logs and give you further instructions, however he comes on the forum late UK time. He will respond to you in this thread, so remember to check this thread daily.
Please do not make any further changes to your machine after you have provided the logs.IMPORTANT: If you are on a home network, disconnect the affected machine from the network. Do not share a USB/flash drive with this affected machine. Do not use this machine unless Essexboy instructs you do to malware removal instructions; use a different machine to check email, sync your phone, etc. if possible.
Let us know if you have any questions. Thank you.
