There have been other reports of AVG exposing and collecting personal data.
There have been numerous complaints about issues and conflicts with other security tools.
There have been reports of issues with the computer starting properly on 64-bit Windows sytems. There have been numerous reported problems with computers after using features like PC Analyzer and AVG PC TuneUp which purport to fix registry errors and various optimizing tweaks which make changes to system settings. Bleeping Computer DOES NOT recommend the use of registry cleaners/optimizers for several reasons...read Why you should not use Registry Cleaners and Optimization Tools. The use of cleaning and tuneup utilities installs numerous files, folders and registry entries throughout the operating system making removal of the anti-virus software more difficult.
There have been complaints of AVG Secure Search and AVG Security Toolbar repeatedly being reinstalled after AVG updates itself even though users intentionally choose to remove them. And finally there have been many user complaints about the lack of adequate AVG Customer Support in addressing issues related to the use of their product.
For these reasons, I no longer recommend AVG as a free alternative anti-virus solution.
BTW, you may want to read...
If folks are looking for a free alternative I generally recommend recommend either Sophos Home Free Antivirus or Bitdefender Anti-virus Free Edition if they prefer not to use Windows 10 Defender.
For those who do not mind a paid for product, I generally recommend ESET NOD32 Anti-Virus or Emsisoft Anti-Malware as they leave a small footprint...meaning they are not intrusive and do not utilize a lot of system resources. Kaspersky Anti-virus is also a good choice for the same reason.
For more suggestions see Choosing an Anti-Virus Program which includes more details why Windows Defender Antivirus with Exploit Guard designed protect against ransomware attacks is a very good choice.
Keep in mind that all free Anti-virus programs now come with toolbars or other bundled software except Bitdefender Free, Sophos Home, Microsoft Security Essentials, and Windows 8/10 Defender.
