These are false-positives. We double-check them every time, of course but we can report that so far there are NO such infections inside Advanced Installer. It's just regular installer code that somehow trips the A/V heuristics.
We are actively monitoring and reporting such false positives to the anti-virus companies and in time they add us to their exception list. Some companies are quicker, others less responsive. In the meanwhile, you can:
- add the package to your local anti-virus exception list
- temporarily disable your A/V while installing AdvInst
- install it inside a non-monitored Virtual Machine
Also please, definitely alert us any time this happen so we can verify and contact the A/V company.
