Windows 10环境下R 4.3.1执行update.packages下载二进制包后报错求助

我在Windows 10系统上运行R 4.3.1时，遇到了包更新失败的问题：执行update.packages(ask = FALSE)命令后，二进制包明明已经下载完成，却突然报错导致更新无法继续，具体的报错及追踪信息如下：

trying URL 'https://cran.rstudio.com/bin/windows/contrib/4.3/xfun_0.40.zip'
Content type 'application/zip' length 434230 bytes (424 KB)
downloaded 424 KB

Error in if (any(diff)) { : missing value where TRUE/FALSE needed

traceback()

5: tools::checkMD5sums(pkgname, file.path(tmpDir, pkgname))
4: unpackPkgZip(foundpkgs[okp, 2L], foundpkgs[okp, 1L], lib, libs_only,
lock)
3: .install.winbinary(pkgs = bins, lib = lib, contriburl = contrib.url(repos,
type2), method = method, available = av2, destdir = destdir,
dependencies = NULL, libs_only = libs_only, quiet = quiet,
...)
2: install.packages(update[instlib == l, "Package"], l, repos = repos,
method = method, ..., type = type)
1: update.packages(ask = FALSE)

后来我终于找到了问题的根源：我的杀毒软件BitDefender检测到acepack.dll感染了Gen:Variant.Tedy.278833，直接把这个文件隔离了。我删除了acepack包之后，其他所有包都顺利完成更新了。
