I had a paid version of MBAM on my system (Windows XP 2002 SP3), and it seemed to work fine for the year or so that it was installed. However, recently my computer would suddenly slow down to a crawl - for example, it would suddenly take 2 minutes to open a folder when I double-clicked on it. This would happen at seemingly random times, when I wasn't doing anything except reading email via a remote shell account.
I investigated the running processes on my PC and discovered that MBAM was running at 100% of CPU time. I was not doing a scan, or using any other feature of MBAM, at the time. It did run as an ongoing background process to monitor potentially malicious sites trying to gain access, but that has never hogged the CPU.
This made me suspicious, so I uninstalled MBAM, and voila - the PC now runs at a normal speed!
Has this happened to anyone else? It is possible that shortly before this started to happen, I got a popup message alerting me to an update for MBAM, but I don't remember exactly when that was or even whether it was MBAM at all (I get alerts about upgrades for various software and I wasn't keeping track of which ones happened when).
Even though I uninstalled MBAM and the PC is now running normally, is it possible that malware is still active on my PC? I'm not seeing any abnormal behavior at the moment.
And I would like to reinstall a legitimate version of MBAM, but I'm not sure how to protect myself from accessing yet another imposter site.
Thank you! I'm sorry, but I don't remember the version number of MBAM - however, I did install it in early 2012, and since it was a paid version, it must have been the latest version.
