hi. i need help

i'm using a laptop with windows 7 home premium 64 bit os

 

long story short i lend my laptop to a co-worker few days ago, and when i get it back "Mcafee Security Scan Plus" is installed on it, which i don't really need since i already have another antimalware (malwarebytes), antivirus and firewall (zonealarm). so i uninstalled the Mcafee.

 

Just now when i tried to run malwarebytes, it won't open. instead i got "this program is blocked by group policy..." message.

so i did the following:

 

1. i went to "safe mode" and try to open malwarebytes there. 

result: it opened just fine... i done a quick scan and got nothing. so i guessed something that is not running in safemode is blocking it

 

2. from there, the "Mcafee SSP" thing pop into my head. so i went and download the "McAfee Consumer Product Removal tool" and run it.

result: i still can't run malwarebytes.

 

please help..

btw i hope this might help:

First of all, Malwarebytes is not an antivirus, you need an active antivirus.

 

What version of Malwarebytes are you running?

Uninstall the 1.75 and download the 2.0.1 version of Malwarebytes Anti-Malware.

Hopefully this will serve as a reminder not to loan your computer anymore, at least your good one(s) anyway. I see my computers just as my car, they're valuable to me & others doesn't take care of them as I would. Years ago I would loan one, but it seemed like every time, there would be all sorts of popup ads, finally I caught on to what was going on. Using my computer to access adult related sites, one former friend carelessly left some images in the Guest folder.

 

When someone wants a loaner, I graciously offer my old XP notebook, most declines. Can't say I blame them.

Performing full disc images weekly and keeping important data off of the 'C' drive as generated can be the best defence against Malware/Ransomware attacks, as well as a wide range of other issues.
