Disturbing influence acquisitions

I use this software for about 2 months.
Calculator 1: Ebay purchases via Paypal are massively disturbed by the virus scanner so that it came to double orders by mistake, there was not to be recognized by the influence of the virus scanner, whether the order could be carried out.

Computer 2: On a laptop, an automatic connection is prevented with the home network by monitoring the WLAN card. Every time I have the so-called. NDIS monitoring issue.

Calculator 3: In a third laptop locked the antivirus Google, so read that right, the search engine Google has been in the https: link locked as a security risk and could no longer be unlock.

Update 04/30/2015: Today I have uninstalled from the last of the three computers Kapersky Internet Security. Me to prevent his purchases via Paypal is then probably overkill.

Conclusion: I'd like a virus scanner, whose work I did not notice. I do not want the antivirus rummfummelt to my firewall, wireless network settings blocks, the browser partially deflects about Kapersky, browser representations changed (which is like malware) and even not ever get with small label indications where the virus scanner has taken root everywhere. Who likes that everything is well served with Kapersky Vireschutz.
