Hello.
The log shows a malware infection, so sometime whenever, it has or had internet connection, either that or someone used an infected USB stick/transported infected files onto the machine.

I've just run a check on a DNS setting, I need to know if you/your ISP is Irish, or located in Ireland.

yes my ISP provider is in Ireland. You helped me last week on my main PC which had malware issues & we do use a usb often to transfer files from my to this pc. I didn't realise you could transfer malware :oops: I do now!

Gonna follow above instructions now, thanks

Hello.
I have edited your log post for privacy because the IP I ran a trace on goes back to exact details, real name/address of what is likely you, or your ISP.

Hello.
Two things here.

First, pleace update the MBAM database, you have an extremely old database running there.

Second, MBAM has found a crack/keygen, remove anymore that maybe lying around, otherwise I will refuse to help you.

"C:\WINDOWS\Adobe PhotoShop CS3 Extended Keygen + Activation.exe (Trojan.Horst) -> Quarantined and deleted successfully."

After an updated scan with MBAM, run this next tool.

Download Lop S&D < here

Double-click Lop S&D.exe
Choose the language, then choose Option 1 (Search)
Wait till the end of the scan
Post the log which is created: (%SystemDrive%\lopR.txt)

"Second, MBAM has found a crack/keygen, remove anymore that maybe lying around, otherwise I will refuse to help you."

What is a crack/keygen? doesn't sound good! did search & it yielded nothing. I bought this Pc 2nd hand had most stuff preinstalled do you think i should do a clean install? have the xp disk that came with it.

A crack/keygen is something hackers use to bypass programs that have to be bought to use fully, like AV's, photoshop, etc. This kind of activity is illegal, so if this machine is second hand, I would probably format it too, god knows what else maybe lurking.

format, thats wiping the drive right? so a clean install & choose option to reformat? Have all pics & music documents etc.. backed up now.
thanks for the advice, i'll do that without further ado.

Okay.
