Kaspersky Internet Security security compromise with Malwarebytes

I run Kaspersky Internet Security (KIS) 15.x as a firewall and antivirus and in addition run MalwareBytes premium home. I have Windows Defender turned off under Windows 7.

During a two week discussion with KIS online support on several topics, the following occurred:

1. KIS support was incredibly obtuse, arrogant, and condescending (I can provide discussion threads).

2. They convinced me to run their Kaspersky Log Utility which collects an immense amount of configuration and registry data. This was not necessary to solve the problem at hand (a problem with their ticketing system). I foolishly ran it and submitted results.

3. They told me to uninstall MalwareBytes. I did not do so.

At this point, I am extremely suspect of KIS and question whether my system has been compromised by their log utility.

I have taken the following steps:
- Uninstalled MalwareBytes.
- Downloaded MalwareBytes and reinstalled.
- Enabled rootkit scan, Shriken Huristics, and self protection early start.
- Ran a full scan.

Do you have any recommendations on any additional steps I should take to ensure system integrity?

Do you have additional information on KIS integrity - or lack thereof?

Would you recommend running Windows Defender in addition to KIS? Both are firewalls as I understand it. It is not recommended to run two firewalls.

Thanks very much,

Fred

You have not described the problem(s) you are having.

Having said that, KIS and MalwareBytes Pro are both full time scanners.  That could cause conflicts.  Try running manual scans with MalwareBytes only occasionally (or use MalwareBytes free).

Windows Defender is not a very effective app to use with Windows 7.  If you want to switch firewalls switch to Windows Firewall.  And as you say running two firewalls is not recommended.  (Windows Firewall will turn a second firewall off.)

Hi:

Thanks for your reply.

Yes, KIS and Malwarebytes can do real-time scanning. I typically run Malwarebytes as a scheduled periodic scan, not as real-time.  KIS is a firewall, but not Malwarebytes (let me know if that is incorrect). Therefore, the two packages should be compatible.

I am not having a problem - that I know of. That's the point of my original post: I want to ensure that both KIS and Malwarebytes are robust and reliable, especially after the support fiasco with KIS.

If it ain't broke, don't fix it.

Yes, KIS offers a firewall and MalwareBytes does not.

what is wrong with windows firewall? Kaspersky is one of the best AV products.  Malware Bytes is better for malware and potentially unwanted programs (PUP's)
