Thanks to @roger_m I was made aware of a free antimalware (AM) called WiseVector (WV) whose website is HERE. Before installing WV I checked forums at Wilders & MalwareTips and found several comments, all of which were favorable. Now that I have installed it I thought I would share a bit of my experiences with you. First off, WV is NOT a signature based AM. Instead it is based on artificial intelligence (AI) -- the new buzz-word used by several AMs (example: SecureAPlus's APEX). The best way to get an idea of what it does is to visit its website, which I linked in first paragraph. Briefly, however, WV promotes itself as specializing in Advanced & Stealth Threat Detection including, but not limited to, zero-day malware detection. My experiences: MV installs quickly & is very easy on system resources. On my aging laptop it uses 39 100ths of 1 percent CPU from time to time, and takes up 7.31MB RAM, as measured by my computer's SysGauge Monitor app. MV's icon is a rocket -- in my system tray its small icon mostly resembles R2D2 of Star Wars fame. I had MV do what it calls a "Quick Scan" -- it took over 30 minutes! Either its scanner is very slow (I doubt that) OR its non-signature-based scan must have to do a lot of messing around with files in order to discern what they might be up to (that's my guess). Anyhow, for whatever reason, I will henceforth do scans only when there's something good to watch on TV or I'm going outside to mow the lawn. Screenshots? NO! Here is a very interesting fact: WV evidently protects itself from having screenshots made of any page of its GUI. I have 3 apps to take screenshots and, on all 3, the instant the app was clicked to target the screenshot, the GUI quickly disappeared. After the shot was taken, the GUI reappeared. I checked -- all screenshots showed a blank screen -- no visible GUI. Therefore, I will verbally describe the GUI. Main page: offers 3 scan types: Quick, Full, & Custom. There are click-spots to access: Log, Exclusions, Quarantine. It offers a choice of 9 skins. It has a drop down menu with 2 choices: Settings, Check for Updates Settings Page, Basic Tab has check boxes for: Load at startup, Enable Real-Time Protection (has a set-up page for that), Auto Updates. Has a drop down menu for selecting strength of its Heuristics (Low, Normal, High, Aggressive) Settings Page, Advanced Tab has check boxes for: Advanced Detection Settings, Anti-Ransomware Settings, Self-Defense, Memory Inspection, Instruction Tracer That's my take. By the way, the language option on WV's website gives 2 choices: (1) English and (2) guess what. Ergo, the country of WV's origin is fairly easy to figure. I hope some of you folks will give WV a spin & let us all know what you think. I am VERY pleased to have such a (potentially) powerful, non-sig, free, light, user-friendly AM in my arsenal. I am hoping that time will eventually prove that it's worth MUCH more than I paid for it.
