I have been trying to uninstall STOPzilla! for 6 months now. I have been on forums and blogs and have tried lots of different things and i keep getting Error: 316 File.. C:/WINDOWS/installer/szprobase.msi When i go to look for this the file doesn't exist. Its about to drive me crazy.. Anysuggestions...

IT's dumb as a box of hair. It hosed my TCP/IP stack, by recognizing valid registry keys as 'malware',, and removed them, after telling me i'd have to 'pay firts'. And what's this $20 mail-in rebate" nonsense? Horesrace, is what it is. It may not be a "torhjan", per se, but it is badly written, and dangerous. DO NOT USE!!!
  Gyro Gearloose  
I cant get it of my computer either. I have tried everything! My computer has been running really bad since i installed it.
  Shelley  
It is a sneaky virus, I downloaded hijack this, ran the scan selected all things that had the words stopzilla in them, went to add remove programs, removed it, and so far so good. It only took me ten minutes to remove it. It is definately a virus, b/c they put this on your computer to force you to purchase their product to remove what they have put on it to begin with. This does NOT sound legal or right either! Good luck everyone! I tried removing it earlier, and it took away my internet access, now that was a bitch to fix, b/c I didn't know where to look, because I had connection! G L all!

Hi All, I use the stopzilla program as a backup spyware scanner I have been useing it for a couple of years now and find it to be a good program, the only thing is that it uses alot of system resourses which is why I use it as a backup scanner. What I do to disable SZ is go; start run type in (services.msc) a window will pop up scroll down to the SZ listing and double click on it another window will open in the startup box change the drop down box to manual this will stop SZ from starting up when you reboot, you can also disable SZ altogeather. In manual mode you can start SZ when you want

It's malicious. After running several virus scans with other programs and finding nothing, I turned to stopzilla, which found 64 infected files. Really? 64 infected files when 4 other reputable scanners found nothing? And you have to pay for StopZilla to fix anything? It's definitely a scam.
  Dan  
well i don't know if it's due to stopzilla or not but has anyone after installing stopzilla noticed that when i used either google or yahoo didn't matter instead of going to the item the search endine found it would start up another search engeine of some unknown nature and most times would not let you go back it wold literally stay on that search engine page and one else experienced this?

I installed StopZilla to aid the removal of a virus that would not go away. Stopzilla finds the virus and claims it is removed but the several viruses reappear within 24 hours. I have removed the infected drive and connected it via USB to run a corporate version of SOPHOS antivirus. Sophos found more viruses that Stopzilla (no surprise). I am suspicious about the StopZilla anti virus application. Is it malware in disguise?
  Mark J  
Stopzilla is a viral program that acts like an antivirus. It is difficult to remove. The only sure way to start computer in safe mode and restore the PC to before it was installed. Then run a complete virus scan of the ENTIRE computer. If that is not an option a clean install of Windows is the only other way to completly remove it and all traces

stopzilla gets knocked off my PC alot. I cant get restored
  paula camp  
I used pre-Oct 2010 version no problem, but very slow. Post-upgrade I have Internet connection, but website won't open on 3/4 s of my Favorites including AOL, Microsoft, amg Google. Disabling Stopzilla/Uninstalling it made no difference.

Avira continues to detect viral activity; I'm trying to dislodge this piece of shit from my system -- will probably cost me $$$ to clean the fucker out.

Stopzilla is definitely a drain on resources and is prone to "False Positives". I have tested it thoroughly on a "sacrificial" computer, where I was innundated with search engine redirects, trojan detections and other malware types detected BUT ONLY by StopZILLA. I completely purged the Trojan "System Tool" which was in fact previously infecting my computer, yet stopzilla returned detection results for this and other listed malware. Malwarebytes AntiMalware, Avast and other antimalware (reputable) applications gave "all clear". Stopzilla can be removed completely by using Piriform's "CCleaner" uninstall tool. Freeware worth supporting. Since Stopzilla seems to have unscrupulous "Affiliates", and cannot control rogue behaviour for Adware, Browser Hijacks and False positives, it can't be regarded as reliable. The irony is that it is a good detection application but permits its utility to be marred by uncertainty and unwarranted User anxiety. I submitted my views by way of a report to Stopzilla (IS3 inc)

I do not see anything wrong. I have used it for about 6 days and so fay thousand of viruses I had are gone and my pc is 300% faster literally. It is a malware though and only does good to you for the first fourteen days. On the thirteenth day delete SZ by going into programs and features. BEFORE YOU DELETE IT AT LEAST HAVE ANOTHER TRIAL VERSION OF ANTIVIRUS. Because once you delete there will be 600 malware and trojan on your computer. But if you di all i said you computer should be brand new again. Also, if you want to speed up your pc go to speeditupfree.com

It has completely disabled my PC. I deleted it, but i can't get on internet.

It ruined my computer
  Victoria Thompson  
Stopzilla is difficult to remove; it insists on you purchasing it; it has many false positives; it is promoted by various forms of adware and redirect viruses soming that NORMAL antiviruses wouldn't resort to
   
Dangerous virus
  Sandy

(295.95) us cash for a years service. 14hrs, 09 hrs and 12 hrs in three consecutive days i was in terrible shape. my refund was refused and the person from india, i say again india finally refunded 5cents on my credit card 2 days before the end of the 30 day guarantee. i will tell you if you fill out the critique form at the end dont say anything no mr room
  kevin  
I'm sure it is some kind of scam. To remove it, go the start menu then search "system restore" You can restore your system to the date before you download stopzilla
  Hannah  
I have deleted over & over. Every time I go to Google, it reinstalls itself. Google Crome doesnt work anymore. I'm affraid I'll have to delete Google Crome & redown load to get rid of the virus.
  Charles Wolfe  
I'm sure I uninstalled STOPzilla some years ago, but I just found a way to check errors on my PC (xp home sp3) and everyday there are numerous errors attributed to STOPzilla. Now seeking help on this matter.

Best practices for resolving STOPzilla issues

A clean and tidy computer is the key requirement for avoiding problems with STOPzilla. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the STOPzilla.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
