NOD32 is acting strange

I have a problem as soon I turn on scanner on demand.First nod instantly
turned off my laptop(thats before scanning my working memory)and the second
time I tried to scan my comp.my display went blue with brown stripes also
before scanning work memory.What should I do?Anyone?Thanks.

 

Hi there, welcome to Wilders.

What previous antivirus was on that system?

Cheers

 

Non I have NOD sence I buy laptop.It is originall nod purchuest at my lokal store.

 

But I do have lawasoft ad aware on my comp.(and ad watch)

 

Most computers (laptops) comes with pre-installed antivirus software such as Norton/McAfee/ sometimes Trend and it is crutial to remove all their tracks before installing new product .

if you have had one of them , check these links and use their special removal tools:

And , uninstall/completely disable Ad-Watch , it may create problems

 

I ll try that thanks.
