I just got my laptop back from a local shop which kindly (for a fee) removed a virus I'd gotten. I'm pretty paranoid; this is the first real infection I've had in several years. But the advice i got from them doesn't match the advice I've seen in this forum, and I'd like to run it by the community for opinions.
My laptop is a Lenovo T530, Win7 Pro 64bit, 8 GB RAM, 450GB hard drive (7200rpm). I also have a custom desktop on an ASUS motherboard, with the same security setup, not currently infected.
My security setup was (still is on the desktop) Microsoft Security Essentials, plus MalwareBytes Pro running real-time protection. I also had WinPatrol installed and running, and CCleaner (I thought) installed but not running, although I find that it was running.
My local techs chewed me out for too many security programs running at once. Having been infected, I decided to take them seriously and remove CCleaner (which I haven't used since I got WinPatrol, I mainly used it to manage the startup list) and WinPatrol. I'm having trouble uninstalling WinPatrol, but that's another issue.
The techs also said I should not run Malwarebytes full time against MSE. I have a Malwarebytes Pro license for both the laptop and a desktop, and I run them in real-time protection mode. Before I set this up I spent a lot of time reading the antivirus and antimalware posts on this site, and I concluded it was OK to run Malwarebytes Pro at the same time I ran MSE. Has thinking changed on this? Should I really not run MBAM full time, against a running MSE? If I want to use it, I have to reinstall it - the techs said the virus "chewed up" Malwarebytes, and I see it has been uninstalled.
