Hello,
1st time poster, my husband's laptop runs Windows 7, avast free antivirus. So kept getting pop up that dnsapi.dll in systemWOW64 has a trojan! tried a boot scan, and others, it says it can't deal with, Error when trying to fix it. So we followed some advice on other forums to deal with it. Tried to run software to clean it up such as spyhunter 4. kept saying that the laptop wasn't on the net, when we could get to web pages. tried to reinstall Windows 7, and have found that now laptop will not connect to the net at all! We are so frustrated. Please help us to deal with this. Thank you in advance.
