Been having an issue where McAfee firewall repeatedly turns off. I can turn it back on manually but it only stays on for around 30 seconds to 1 min. When the firewall is off the internet connection is seemingly blocked. On chrome I receive the message
"Google Chrome is having trouble accessing the network.
This may be because your firewall or antivirus software wrongly thinks that Google Chrome is an intruder on your computer and is blocking it from connecting to the Internet."
If I manually turn the firewall back on the internet connection resumes but only for the 30 seconds that the firewall stays on.
I'm assuming this is some sort of malware? I'm unsure what to do.
Scanning with McAfee and MBAM leads to no results.
Have previously scanned with TDSSkiller but that too reports no results.
