Hi wondering if anybody could help out keep getting a detection note from my Avira security stating
Virus or unwanted program 'TR/Crypt.XPACK.Gen [trojan]'
detected in file 'C:\WINDOWS\Temp\munw.tmp\svchost.exe.
I deny access but keeps popping up about every 5 minutes I have run scan on both Avira and Malwarebytes but both scans fine please see below

Scan in safe mode, hold down F8 at bootup to get there.

Cleaning up your temp files might also help, https://www.ccleaner.com

Take off Avira and install Microsoft security essentials

FWIW it sounds like this:

Also, you have only run a Malwarebytes QUICK scan.

It could make a difference.

not been at home for a couple of days and still getting the same detection warning have read the above link and seems a little techie to me, is there anything else I could try ? should I still uninstall Avira and install microsoft security ess. and if so do I do this via the microsoft website. I have run a Malwarebytes quick scan and full scan and no differance, sorry about all the questions but not very techie myself and everyones advise is really appriciated.

See if you can delete this directory manually, and empty the recycle bin

C:\WINDOWS\Temp\munw.tmp

Did you do the safe mode scan, and clean up temp?

If you have, download hijackthis from trendmicro, and post a log.

Thanks for the reply, I did try and start in safe mode but wouldn't allow I have also done ccleaner but still getting detection warning ... how would I manually delete C:\WINDOWS\Temp\munw.tmp and I have also emptied the recycle bin will run hijackthis and post.

manually delete in explorer, highlight the directory, hit delete.

why wouldn't safe mode work?
